AN315 (REV. 10) (NOTICE 2)., AIR FORCE-NAVY AERONAUTICAL STANDARD: Nut, Plain, Castellated, Airframe (23 SEP 2002) [S/S BY NASM315]., AN315 REV. 10, dated 29 DECEMBER 1972, is hereby canceled and superseded by NASM315. The Part Identification Number (PIN) for AN315 REV. 10 and the part number for NASM315 are identical. The part numbers have not been changed.

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. They are offered as OEM parts under their respective brands or under our own labelled (AVIATIONEU NEW ERA) product lines intended as cost-effective alternatives to the respective OEM products. Listed in accordance with their standard of compliance, Fixed and Floating nutplates come in different materials (such as steel or CRES & finishes),  in single/double lug configurations and Metric ISO οr Unified thread sizes. There is currently no U.S. Military Standard (MS) specification for Metric nutplates.Depending on the selected product and availability, nutplates can be supplied with a dry film lube specified by the letter "L" in the respective part number. Those with countersunk rivet holes are specified by the letter "K" at the end of the part number.

Sourced from quality manufacturers, AVIATIONEU NEW ERA MS21071/MS21072 series nutplates are fixed self-locking, low height one-lug, reduced rivet spacing miniature anchor nuts. Those included in MS21071 series are manufactured from cadmium plated carbon steel while the MS21072 nutplates are produced from corrosion resistant steel (CRES). They are available in different Unified thread sizes, with plain or countersunk rivet holes on each side and come with or without a dry film lube. Sold in pieces but also in packs where the specified number of nuts per pack is indicated after the letters "PK" in the product reference number (SKU). Appearing prices are always for the units of measurement used each time. Matching rivets are sold separately.

For additional information please refer to the supplied documentation or contact us.

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).

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.

Certification Details:

AN316 (REV. 11)., AIR FORCE-NAVY AERONAUTICAL STANDARD: Nut, Jam, Hexagon (25 Feb 1991). Superseded by NASM316. The Part Identification Number (PIN) for AN316 and the part number for NASM316 are identical. The part numbers have not been changed.

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.

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. They are offered as OEM parts under their respective brands or under our own labelled (AVIATIONEU NEW ERA) product lines intended as cost-effective alternatives to the respective OEM products. Listed in accordance with their standard of compliance, Fixed and Floating nutplates come in different materials (such as steel or CRES & finishes),  in single/double lug configurations and Metric ISO οr Unified thread sizes. There is currently no U.S. Military Standard (MS) specification for Metric nutplates. Depending on the selected product and availability, nutplates can be supplied with a dry film lube specified by the letter "L" in the respective part number. Those with countersunk rivet holes are specified by the letter "K" at the end of the part number.

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.
