Aircraft General Standards (AGS) were issued by the Directorate of Technical Development of the Air Ministry from the 1920’s and persist till today through substitutions to British Standards and AGS revisions. They relate to fasteners  such as bolts, nuts, rivets, fork joints, taper pins, common to all types of aircraft. AGS fasteners are made in a range of sizes and different materials. In their identification system AGS parts are listed in sequential number, eg AGS 500, AGS 501 even though the number does not generally group common parts together nor does it follow a specific chronological order. Special parts made for specific aircraft have no marking to indicate size or material, but are marked with a part number.

Anchor nuts (aka nut plates) are designed for blind mounted applications where it is impractical to use hex nuts. Stiffnuts, in particular, feature a very high friction between the threads of the nut and the bolt so that the nut may be considered self-locking. Several types of stiffnuts have been designed for use on aircraft. AGS 2007 series relates to double lug anchor locking nuts (aka thick stiffnuts) while  those in AGS 2008 and 2009 series relate to thin and countersunk stiffnuts.

AGS 2007 series anchor nuts are offered as nyloc (*) (with nylon-insert) or all-metal style. They can be furnished in different materials (aluminum, cadmium plated steel or corrosion resistant steel (CRES). Available with BA or BSF (**) threads as NEW OLD STOCK (NOS) items in limited quantities from  stocks of our co-operating suppliers as special order non refundable and non-returnable items. Please refer to the supplied documentation or contact us.

(*) Nyloc nut (aka nylon-insert lock nut, polymer-insert lock nut, or elastic stop nut) is a kind of locknut with a nylon collar that increases friction on the screw thread.

(**) British Association (BA) Threads. small sized screw threads still used in some precision instruments, such as optics and moving-coil meters, relays as well as modelling applications. Recommended by the British Standards Institution for use instead of the smaller British Standard Whitworth (BSW) and British Standard Fine (BSF) thread screws (those below 1⁄4 inch).

British Standard Fine (BSF) Threads. Screw thread form, used as a fine-pitch alternative to British Standard Whitworth (BSW) threads. Common applications include British machine tool industry and cars. Superseded by the American UNF threads and later Metric standards.

Machine screws are one of the more widely used products among dozens of standard fastener types. They can be either coarse-threaded or fine-threaded, and are usually available with a wide range of head types. Usually stronger than many other screw types, they are used for fastening metal parts and panels securely together in a range of construction and other applications including aerospace, machinery, vehicles, engines, tool assemblies, electronic devices, and large-scale industrial equipment. 

Sourced from quality producers,  machine screws are offered as part of our own branded (AVIATIONEU NEW ERA) product lines conforming to aerospace/military or industrial standards/specifications.  They come in different sizes, head types, materials and thread gradings. Countersunk screws allow the head of the screw to sit flush with or below the surface of the surrounding material. They may also be used to remove the burr left from a drilling or tapping operation thereby improving the finish of the product and removing any hazardous sharp edges.

AVIATIONEU NEW ERA MS35206 and MS35207 series of machine (non structural) screws are mil spec pan head cross recessed (Phillips) screws, manufactured from carbon steel and are cadmium plated to specification QQ-P-416, Type 2, Class 3.

SAE AISI(*) 1018 (G10180**) (separately presented) & 1020 (G10200**) mild/low carbon steel grades are are iron alloys with basically identical composition. Please refer to the supplied documentation for the comparison of SAE AISI 1018/1020 steel properties and additional information provided at the Product Description section. Technical data of supplied materials should be used ONLY FOR REFERENCE, NOT FOR DESIGN, and any decisions on their use remain entirely at the buyer discretion.

SAE AISI 1020 steel, aka C1020 steel in cold worked condition, is one of the most commonly used plain carbon steels. It is a low hardness and tensile strength carbon steel alloy with Brinell hardness ranging between  119 - 235 and tensile strength between 410 - 790 MPa. It features high machinability, high strength, high ductility and good weldability by most welding processes supporting its use in all industrial sectors. Due to its low carbon content, it is resistant to induction hardening or flame hardening but carburization or carbon nitriding can be applied to achieve a hardness value of more than  Rc65.  Normally used in turned and polished or cold drawn conditions.

Sourced from quality producers, SAE AISI 1020 steel tubes are offered as part of our own branded (AVIATIONEU NEW ERA) product lines. They can be furnished Normalized, Annealed or in other conditions, in different specifications, different shapes (cross sections), round, square, rectangular, etc. and dimensions in inches or millimeters (depending on the supplier) to meet project requirements. In the case of Metric round tubes, they are cold drawn seamless tubes available in different outer diameters and wall thicknesses in mm and pre cut or cut to order lengths in meters or centimeters. Those in inch system  are offered as DOM (Drawn Over a Mandrel***), with outer diameters and wall thicknesses in inches and lenghts in inches or feet.  Although they are welded tubes, the weld line becomes nearly undetectable during the manufacturing process and they are often referred to as seamless. Appearing prices for pre cut tubes are per piece in indicated dimensions.

(***) A process applied to tubing after its initial construction, allowing more exact ID/OD dimensions, a smoother finish, and a better alignment of the crystal lattice structure. 

Anchor nuts (aka nutplates or anchor plates) are terms used interchangeably and relate to stamped sheet metal fasteners with an internally threaded tube and a plate with two clearance holes for rivets. Initially designed and still extensively used in aerospace applications, they are today also used in automotive, motorsports, and other industries in blind mounted panel applications where hex nuts cannot be used or an attached nut is required for ease of maintenance. They can be Fixed or Floating, the latter being easier to install due to their built-in nut (threaded hole) able to "float" slightly thus providing a convenient connection point for threaded rods, such as bolts, from the backside. In the case of Fixed anchor nuts, the built-in nut is static (i.e. without the capability to “float”) and the threaded bolt must be positioned perfectly over the hole. Self-locking anchor nuts are those with a built-in locking mechanism preventing them from loosening over time from vibrations.

Anchor nuts are offered in Imperial (in.) and Metric thread sizes, in different materials (e.g. Carbon Steel, Steel alloys, CRES), finishes such as Cadmium or Cadmium Free Zinc Nickel platings (compliant to EU Regulations) with or without dry film lubrication. They come in various styles/configurations (e.g. with one or two lugs, full size or miniatures, countersunk, corner, right-angled bodies, etc.). They conform to different U.S., European and international standards such as the US Military MS and NASM, German DIN LN, French AFNOR NF, British BS, ISO and others.

Depending on the selected nutplate, aerospace anchor nuts are produced by different manufacurers, such as HOWMET AEROSPACE (formerly ARCONIC) or PAOLO ASTORI, and others, and offered as respective OEM parts or as parts of our own labelled (AVIATIONEU NEW ERA) product lines in the case of those used in industrial applications.

Grade 410 is a basic general-purpose hardenable martensitic stainless steel alloy for highly stressed requirements, providing good corrosion resistance. Martensitic stainless steels are fabricated using techniques requiring final heat treatment. These grades are less resistant to corrosion when compared to those of austenitic. Their operating temperatures are often affected by their loss of strength at high temperatures, due to over-tempering and loss of ductility at sub-zero temperatures. Quenching and tempering can harden grade 410 steels while their corrosion resistance can be further enhanced by hardening, tempering and polishing. 

410 is a very common grade used in many industries such as aerospace, power generation, and general industry. Generally used for applications requiring mild corrosion, heat resistance and high strength and ductility. Indicative examples include steam / gas turbine blades and buckets, bushings, valve components, fasteners, nuclear reactor control rod mechanisms, petrochemical equipment and machine parts.

National Aerospace Standards (NAS) are voluntary standards developed and maintained by committees and working groups of subject matter experts from member companies of the U.S. Aerospace Industries Association (AIA).

These standards have served as the foundation for the development of aircraft, spacecraft, watercraft, ground vehicles, machinery, and electronics.

NAS parts are most well-known for state-of-the-art, high-strength, precision fasteners, electrical connectors, splices and terminations, rod end bearings, and many other types of hardware and components. The NA prefix relates to metric standards. 

NAS 1022 Series Hex Self-Locking Machine Nuts form part of NAS high-strength, precision fasteners. These low height and strength hexagon machine nuts are sourced from quality manufacturers and offered in different materials and finishes as part of our own labelled (AVIATIONEU NEW ERA) product lines in different thread sizes and dimensions in inches. Those from 450 deg. low strength steel are designated by the letter "A" after NAS1022. Similarly, the letter "C" designates nuts from corrosion resisting steel passivated while the letter "N" refers to steel cad plated nuts.

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.

Note: Depending on availability,these parts part may be supplied without or with Dry-Film Lubricant indicated by letter "L" in the SKU.
