Please refer to the Product Description Section for an indicative list of available packs.

Self-locking nuts (aka lock nuts) are widely used in applications in which motion or vibration can cause fasteners to become loose. Lock nuts conforming to DIN 980 stanard are all metal prevailing torque, hexagonal nuts and they  are available in two types, DIN 980 V-type (DIN980/V) with a distorted thread and DIN 980 M-type ((DIN980/M) with an embedded metal locking plate.

In DIN 980 V-type distorted thread nuts, certain teeth of the nut thread are deformed through die stamping resulting in the inner diameter of the nut thread being slightly smaller than the outer diameter of the bolt thread. Therefore, the friction force between the threads after the nut is tightened is far greater than that of the common thread, which can play an effective role in preventing loosing. 

In DIN 980 M-type nuts, the nut is embedded with a metal locking plate after heat treatment. The inner diameter of the metal plate is slightly smaller than the outer diameter of the bolt thread. After the nut is tightened, the metal plate blocks the bolt thread, thus preventing loosening.

DIN 980 lock nuts must be tightened with tools (such as ratchet spanner) during installation. Although they can be can be used repeatedly, frequent disassemblies and installations are not recommended as the locking torque of the nut will decrease significantly.

Depending on the producer, DIN 980 lock nuts are manufactured in different metric thread sizes (M3 ~ M39) from carbon steel in various strength classes (such as  4, 6, 8, 10 and 12) or stainless steel in grades 70 and  80. They are offered in various finishes such as plain, black, zinc/yellow plated, H.D.G, and chrome plated.

Both DIN980/V and DIN980/M lock nuts are offered as part of our own (AVIATIONEU NEW ERA) product lines. Sourced from quality manufactuurers they are competitively priced and can be supplied in carbon steel or stainless steel, in different grades, metric thread sizes  and finishes .

For additional information please consult the supplied documentation.

Notes:

Different metric thread sizes are designated by the letter "M" indicating the nut's clearance diameter in mm.

Nut thread pitch indicates the distance between threads measured along the length of the nut expressed in mm.

In the case of stainless steel lock nuts, the stainless steel grades are denoted with codes such as A2 or A4 and dash numbers indicating the minimum tensile strength to be met by the material. For example, A2-70 relates to a lock nut made from 304 stainless steel with a minimum tensile strength of 700N/mm² (MPa).

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. They are used in blind mounted panel applications in aerospace and other industrial sectors where hex nuts cannot be used or an attached nut is required for ease of maintenance. 

Anchor nuts can be Fixed or Floating, the latter being easier to use 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 rod 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. They are extensively used in aerospace, automotive, and construction industries.

Depending on their intended application, nutplates conform to different military, aerospace, ISO or other industrial standards such as the German DIN, U.S. (ASME & ASTM, IFI, ANSI), British BS, Japanese JIS and others.

A nylon-insert lock nut (also referred to as elastic stop nut, nut with a non-metallic insert  or nyloc nut) is a type of locknut with a nylon collar that increases friction on the screw thread. Nyloc nuts are widely used in products and structures subject to dynamic loads where motion or vibration can cause fasteners to become loose. Their design prevents the connection from loosening without the need for additional lock washers.The nylon insert is situated at the top of the nut and when tightened locks against the thread. The insert deforms elastically over the threads as tightening pressure is applied. The insert locks the nut against the screw as a result of friction, caused by the radial compressive force resulting from the deformation of the nylon. Nyloc nuts retain their locking ability up to 250 °F.

Metric hexagonal nylon-insert self-locking nuts are high anti vibration and anti loose fastening parts conforming to DIN 982 and DIN 985 standards. Different metric thread sizes are designated by the letter "M" indicating the nut's clearance diameter in mm. The main difference between DIN 982 & DIN 985 is the height of the nuts for same thread diameter. DIN 982 lock nuts (often termed as “P” Type) are taller than DIN 985 (aka “T” Type) ones. Lower profile  DIN 985 are used in places where height is limited, while standard height DIN 982 nuts are used in connections where increased strength and fixation are required. In addition, the size range of DIN 985 nuts is wider than that of DIN 982. DIN 985 Nylon self-locking nuts can be used in various mechanical and electrical products with temperature from – 50 ℃ to 100 ℃. Due to their significantly higher anti vibration and anti loose performance than other anti loose devices, their application ranges from  tanks, mining, agricultural, textile &  various kinds of machinery to automobiles and aerospace.

Both DIN 982 and DIN 985 lock nuts are offered as part of our own (AVIATIONEU NEW ERA) product lines. Sourced from quality manufacturers they are competitively priced and can be supplied in different materials (Steel, Brass, Carbon Steel, Alloy Steel & Stainless Steel), grades (Class 5, 6, 8 or 10), metric thread diameters (typically M3/3 mm to M30/30 mm or up to 48 mm for DIN 985 nuts), thread pitches and finishes (natural, electro zinc-plated, chrome plated, black oxide and others). Sold in pieces or packs with number of pieces per pack indicated after "PK" designation in product SKU.

Notes:

Nut thread pitch indicates the distance between threads measured along the length of the nut expressed in mm.

In the case of stainless steel lock nuts, the stainless steel grades are denoted with codes such as A2 or A4 and dash numbers indicating the minimum tensile strength to be met by the material. For example, A2-70 relates to a nylon-insert lock nut made from 304 stainless steel with a minimum tensile strength of 700N/mm² (MPa).

Steel Nut Specifications:

Material - 4130 Alloy Steel Per AMS-S-6758

Finish - Cad Type II, Class 2 Per AMS-QQ-P-416

Heat Treat- 150 KSI Min Per AMS2759

Hardness - 34-38 HRC

Thread Series & Class: UNJF 3B (Unified National Fine thread series with external thread controlled root radius)

Note: UNJ, UNJC, UNJF and UNJEF thread series are almost identical to the respective UN, UNC, UNF, and UNEF threads except that the external J thread has a much larger root radius than the standard UN threads and inspection must be performed on this element. The Special UNJ threads are designated by the nomenclature UNJS. J screw threads feature a root radius which improves the tensile stress area of the fastener and helps to reduce the stress concentration factor in the thread thus making the thread stronger. Additionally, the requirement for high strength is achieved with 3A and 3B classes of fit. All pitch diameters and tolerances are based on the Unified Inch Standard.

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 1791 and 1792 Series fasteners are Floating Self-Locking Nut Plates(*) with variable counterbore replacement nut elements and as supplied in one-lug (NAS 1792) or two-Lug (NAS 1791) configurations. Both form part of NAS high-strength, precision fasteners. They are offered in alloy/carbon steel or corrosion resistant (CRES) materials, in different finishes, thread sizes and dimensions in inches. They can be used in applications with 450°F maximum temperature requirement while those from silver plated A286 Stainless Steel can withstand temperatures up to 800°F.

Sourced from quality manufacturers they are offered as OEM parts of their respective manufacturers or as parts of the respective Standard under our own labelled (AVIATIONEU NEW ERA) product lines. Sold in pieces or packs with specified number of anchor nuts per pack as indicated by the number after the letters "PK" in the product reference number (SKU).

For additional information please consult the supplied documentation or contact us.

(*) Also termed as plate nuts, anchor nuts or anchor plates. Appearing lengths in NAS 1791 nut pllates are distance between centers of mounting holes.

HI-SHEAR Fasteners are patented fasteners of HI-SHEAR CORPORATION (Patent Holder), subsidiary of LISI AEROSPACE, a manufacturer of advanced aerospace fasteners and installation equipment used in space, military and commercial vehicles. Depending on the fastener, they are made by quality fastener manufacturers (licensees) in different  countries including but not limited to LISI AEROSPACE companies, HOWMET ALCOA / SIMMONDS / FAIRCHILD, PCC  SPS, and others. 

HI-SHEAR nuts and collars are designed to fit with their related HI-LOK™/HI-TIGUE™ and HI-LITE™ pins  (separately presented) forming the respective fastener system. HI-LOK™ nuts and collars are designed to fit HI-LOK™ & HI-TIGUE™ pins. HI-LITE™ nuts and collars are designed to fit HI-LITE™, PULL-IN™, PULL-STEM™ & TAPER HI-LITE™ pins.

With a wide range of shapes, materials and coatings, they are suited for most of structural assemblies and are commonly used in the aerospace industry in tension and shear applications. Collars’ wrenching element is designed to break-away at a controlled preload. It has been tested over time and has proven its reliability when installed with non-torque-controlled tools. Main features of nuts and collars include:

- controlled preload

- wide variety of materials and coatings for installation in all structures

- suitable for shear or tension applications, with captive washer, self-aligning or self-sealing options

- limited access installation, using conventional tooling

- designed with a counterbore to fit nominal and oversized pins

- nuts allow customized torque and preload & low height design for low access areas

AN315/NASM315 Series hex plain nuts are manufactured from steel and cadmium plated per QQ-P-416A, Type II, Class 3, corrosion resistance steel or aluminum alloys. The AN315 nuts have been superseded by NASM315 Series. Similar to common nuts  but with a rugged construction they are designed and built with aviation grade materials and to specific aviation design specifications. They can carry the same high tension load as the AN310 castle nuts and require an auxiliary locking device such as a check nut or lock washer. 

Sourced from quality producers, the AN315/NASM315 Series hex plain nuts are offered as part of AVIATIONEU NEW ERA product lines in different thicknesses and thread sizes in inches. The following letters are used to designate specific types of airframe nuts:

"C" before dash number for corrosion resistance steel nuts

"D" before dash number for aluminum-alloy nuts

"L" after dash number for left-hand thread

"R" after dash number for right-hand thread
