A castellated nut, also referred to as a castle nut or slotted nut, is a nut with slots (notches) cut into one end. Although castellated nuts are frequently referred to as slotted nuts, there are slight differences. Castellated nuts are formed with a round section at the top where the slots are located. Slotted nuts do not have this rounded modification. The flat sides of slotted nuts extend fully from the top to the bottom of the nut. Both castellated and slotted nuts are designed to use a pin (usually a split pin) that fits through the slots and through a hole in the screw to which the nut is attached. This pin prevents the nut from turning and loosening. Compared with slotted nuts, castellated nuts allow the cotter pin to be confined closer to the margins of the nut itself, providing added secureness.

MS14144 Series nuts are slotted hexagon style lightweight castellated self locking nuts manufactured from steel and cadmium plated. They are offered as part of our own labelled (AVIATIONEU NEW ERA) product lines in different sizes with right-hand thread direction and a dry film lubricant as applicable, specified by the letter "L" in the part number.

O-rings (also termed as Preformed Packings) offer effective sealing over wide ranges of pressure, temperature, and movement, with the advantage of sealing pressure in both directions and reducing friction and wear on moving parts. The selection of a specific O-ring is based on a variety of factors, including fluid media resistance, temperature range, hardness, durability, gland size, static or dynamic application, etc. The use of O-rings as gaskets or static seals permits metal-to-metal contact and allows almost unlimited pressures under extreme vibration. All O-rings should be lubricated before installation and constant lubrication should be provided for running seals to avoid excessive wear. Sharp edges, threads, and cross-drilled ports over or through which rings must be installed should be avoided.

An extensive selection of O-rings can be supplied as part of OEM brands or sourced from quality manufacturers and offered as part of our own (AVIATIONEU NEW ERA) product lines. They are made from different materials such as Nitrile/Buna-N (NBR), Butadiene (Synthetic) Rubber (BR), Flurocarbon (Viton®) rubber  and others. Conform to various Military, Aeronautical & other Standards. They come in different  Metric or Imperial (inch) sizes (internal/outer diameters and thicknesses (cross-sections) , and hardnesses to suit application needs. 

Those of Military Standard MS28775 are synthetic rubber (Butadiene Rubber (BR))o-rings replacing respective o-rings of AN6227 and AN6230 series. Respective parts of MS28775 are superseded by those of SAE AS28775. Sourced from quality manufactuurers they are supplied in competitively priced packs in different internal/outer diameters and cross-sections (thicknesses) in inches. MS28775 O-rings meet Spec. MIL-P- 5510A and are suitable for MIL-H-560B type hydraulic fluid oil in Type I systems @ -65°F to 275°F. AN6227 standard o-rings (packing) and AN6230 o-rings (gasket)are manufactured to Spec. MIL-P 25732 for use in hydraulic systems using MIL-0-5606 hydraulic oils. For sizing information on MS28775 rubber o-rings and their correlation to AN6227 and AN6230 please consult the sizing table available in the Attachment section.Other offered O-rings are separately listed.For brief presentations of our offered packings please consult the Product Description Section or contact us for further information.

The German DIN 3771 standard refers to all O-rings as sealing elements for fluid technology and identifies O-Ring sizes by their Inner Diameter (ID) &Cross Section (C/S). This standard has essentially been incorporated into the international standard ISO 3601 which sets the globally relevant O-ring dimensions and uniform rules for installation spaces and the properties of the O-rings. It defines metric O-rings according to the same dimension chart as DIN 3771 while it has been extended to include O-rings in imperial dimensions. ISO 3601 also goes beyond the German standard in the area of materials containing material requirements for O-rings that far exceed those of DIN 3771.

Elastomer materials suitable for certain sealing situations are referred to by their abbreviation according to DIN ISO 1629 and include: 

Nitrile/Buna-N (NBR), presently the seal industry’s most widely used elastometer, Ethylene-Propylene (EPM/EPDM) used extensively for outdoor, weather-resistant uses and water applications, 

Silicone (MQ, PMQ, VMQ, PVMQ) especially resistant to high, dry heat in primarily static applications, 

Neoprene® (Chloroprene) (CR) developed as oil-resistant substitute for natural rubber with resistance to ammonia and Freon® and therefore a superior sealing material for the refrigeration industry, 

Fluorocarbon compounds (FPM / Viton®) / (Fluorel®) (FKM) combining high-temperature toughness with wide chemical agent compatibility, and 

Fluorosilicone (FVMQ) combining the good high and low temperature stability of silicones with the fuel, oil and solvent resistance of fluorocarbons.

ISO 3601 / DIN 3771 standard O-rings are offered as part of our own (AVIATIONEU NEW ERA) product lines. Sourced from quality manufactuurers they are supplied in competitively priced packs in different materials, sizes, and hardnesses as specified by a two-digit Shore A durometer number,ranging from 20 (soft) to 90 (hard), depending on the type of elastomer.

For additional information please consult the Product Description section or contact us.

Flurocarbon rubber compounds (also known as FPM, FKM, or trade names Viton®, Fluorel®, Technoflon®, Dai-El® ) combine high-temperature toughness with wide chemical agent compatibility,  and feature excellent resistance to petroleum products and solvents and good high-temperature compression set characteristics. The designations FPM, FKM and Viton® very often cause confusion although they all relate to one single base material. FPM is the international abbreviation according to DIN/ISO, FKM is the short form for the fluoroelastomer category according to the American standard ASTM while Viton® is the registered trade mark of DuPont Performance Elastomers.

M83248 series Flurocarbon rubber o-rings feature an extremely high fuel and heat resistance and they ideally suited for aircraft fuel system applications. These o-rings feature a high temperature resistance, excellent resistance to acids, fuels, mineral and vegetable oils and greases, aliphatic, aromatic and chlorinated hydrocarbons, non-flammable hydraulic fluids (HFD) and many organic solvents and chemicals, low swelling in ASTM oil No. 1, and IRM 902 and IRM 903, excellent resistance to aging and ozone as well as low gas permeability and low compression set.

Flurocarbon rubber o-rings are often used in place of those made by Nitrile rubber (NBR) also known as Buna-N, presently the seal industry’s most widely used elastometer. When it comes to selecting Buna (NBR) vs. Flurocarbon (Viton®)  for sealing applications, the selected material should be selected on the basis of the intended application. Viton and Buna are two durable, elastomer materials and they are both commonly used in sealing applications for O-rings and gaskets. 

M83248 series Flurocarbon rubber o-rings are offered as part of our own (AVIATIONEU NEW ERA) product lines. Sourced from quality manufactuurers they are supplied in competitively priced packs in different sizes.

For additional information Flurocarbon amd Nitrile/Buna-N materials please consult the Product Description section or contact us.

Preformed packings are basically a type of O-ring providing effective sealing over wide ranges of pressure, temperature, and movement, with the advantage of sealing pressure in both directions and reducing friction and wear on moving parts. They are used to prevent leaks and improve aircraft performance. The packings are formed prior to shipping and they are supplied ready to use. Compared to form-in-place gaskets, they offer easy installation without sacrifising performance. Typically made of a slightly flexible material that can be compressed to create a better seal.

The selection of a specific O-ring is based on a variety of factors, including fluid media resistance, temperature range, hardness, durability, gland size, static or dynamic application, etc. 

An extensive selection of preformed packings to choose from can be supplied as part of OEM brands or sourced from quality manufacturers and offered as part of our own (AVIATIONEU NEW ERA) product lines.

Close tolerance bolts, designed with a greater emphasis on measurement accuracy than other types of bolts, are commonly used in the aerospace manufacturing industry. They are threaded fasteners with a shank and head and a tolerance of just +0.000, -0.0005 inch as an acceptable range of variance. The shank is threaded, thus allowing them to be driven into a threaded hole. They intend to eliminate problems appearing when using traditional bolts which have a greater acceptable range of variance. Close tolerance bolts have closer shank tolerances than that of traditional bolts and fit more securely in threaded holes. For some fastening applications, traditional bolts may suffice. For sensitive fastening applications in which precision is required, close tolerance bolts are typically used. When selecting close tolerance instead of traditional bolts the drive type should be considered. Most close tolerance bolts have a recess within their head that supports a specific bit, such as a Phillips head bit. Regarding their threading, all close tolerance bolts, as well as traditional bolts, have threading. But the way in which the threading is designed may vary. Some bolts have more threading on their shank than others, and some bolts have finer threading than others.

Close tolerance bolts are offered in different materials with high-carbon steel being a common material used in their construction. 

Army & Navy (AN) close tolerance bolts are offered as part of our own labelled (AVIATIONEU NEW ERA) lines of fasteners. They are sourced from quality manufacturers and structured in different series (AN 173/174/175/176/178/180).

For example, a 90° elbow fitting with a flared tube 3/8 in. size connection corresponds to PN AS1034D0606 when made from Aluminum Alloy or AS1034W0606 when made from 7075-T73 Aluminum Alloy replacing respective AN821-6D 90° elbow fitting from Anodized Aluminum Alloy with a 37 deg flared tube 3/8 in. connection, and a  UNJF / Class 3A thread of 9/16-18 in. size. AN821 fittings of tube outer diameters  3/4 in. (size 12) and above come with UNJ / Class 3A threads.

Depending on their Part Number they are sold in pieces but also in packs a with specified number of fittings indicated after the letters "PK" in the product reference number (SKU).

Note: In SAE AS standards for new designs, aluminum fittings with material code letter D in their Part or Identifying Number (PIN) are replaced by those with material code letter W for Aluminum Alloy 7075-T73 providing a higher tensile strength. In addition CRES fittings with material code letter S can be used for replacement parts. For new designs use of CRES fittings with material code letter R is recommended for applications requiring higher temperature.

The fitting composition is designated by a code letter in the part number of the fitting (No code letter for Steel, “D” for Aluminum Alloy, “J” for 304 Stainless Steel (CRES), “K” for 316 Stainless Steel or “T” for Titanium Alloy. Depending on their Part Number they are sold in pieces but mostly in packs a with specified number of fittings indicated after the letters "PK" in the product reference number (SKU).

AN823 45° Flared Tube & Pipe Thread Elbow Fittings are superseded by those of Military Standard MS20823 and these are superseded in turn by SAE-AS5196 standard. These fittings are  offered as part of AVIATIONEU NEW ERA product lines in steel or aluminum in different tube outer diameters and thread sizes in inches. Aluminum fittings are designated by the letter "D" after the suffix number.

Restraint systems are today widely used in aerospace, defense, transportation, automotive, construction and many other industries. Attached to an anchorage device by means of a suitable lanyard they are used as personal protective equipment to prevent persons from falling or safely holding them at a specific position. Safety seatbelts and shoulder harnesses are considered primary restraint systems because of their vital role in their users' safety. Those used on general aviation or civil aircraft include different types such as traditional 2-Point or 3-Point restraints which protect air, flight crews and passengers.3-Point restraints are used on modern automobiles while 4-Point restraints are encountered on racing vechicles.

Current listing includes a range of complete assemblies of safety seatbelts and shoulder harnesses, individual components and their mounting hardware. They are suitable for use in many non-certifed aircraft applications like ultra-lights or experimental aircraft, on cars or trucks, racing vehicles and many other applications. Sourced from quality suppliers they are offered in different materials, types and colors depending on the offered product. Cargo tie-down products are also included in this listing. For certified aircraft restraint systems please refer to our respective listings.

Screws, bolts and nuts are standard fastening hardware widely used in a range of applications. 

Internal wrenching (also known as Allen) fasteners are threaded fasteners. Screws and bolts have a drive recess within the head allowing the insertion of an internal wrench for their installation or removal. Allen socket set screws are blind (headless) fasteners with an internal hex drive offered in different styles (regular cap screw and flat and button type) while Allen nuts are cylindrical nuts internally threaded on one side with an Allen socket on the other. These fasteners are produced by different manufacturers and come in different styles, inch or Metric sizes, materials, finishes,  and coarse or fine threadings. They are offered as OEM parts or parts of AVIATIONEU NEW ERA product lines. Sold in pieces or packs of specified number of pieces per pack as designated by the number after the letters "PK" in the product reference code (SKU). 

Internal wrenching fasteners for aerospace applications are designed and intended for use in aircraft construction and repair and conform to Military or Aerospace Standards. Aerospace Industries Association Standard NASM 20004 through 20024 internal wrenching bolts supersede respective part numbers of MS 20004 through 20024 which in turn have superseeded those of older National Aerospace Standard NAS NAS 144 to 158 series. Fabricated from 160-180 ksi high-strength steel they are intended for use in both tension and shear applications. 

Socket screws for aerospace and military uses come in different sizes and meet aerospace/military standards including AN565 (superseded by NASM565), NAS1081, MS18063, MS18064, MS51021, MS51023, MS51029, MS51031, MS51038, MS51045, MS51963, MS51964, MS51965, MS51966. Those of AN565 (NASM565) standard are headless hex and fluted socket set screws while their MS51963 standard counterparts are cup point hex socket set screws.  Both are made of high-quality steel and they are designed to deliver maximum holding pressure Typically used to bind parts onto shafts. Available in cup or cone point styles, in different thread sizes and lengths in inches.
