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.

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 MS21055/MS21056 series nutplates are fixed self-locking, low height corner nut plates. MS21055 series nutplates are manufactured from cadmium plated carbon steel while those in MS21056 series 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.

They are offered as OEM parts or parts falling under our own labelled (AVIATIONEU NEW ERA) product lines in different materials, finishes, thread sizes and dimensions in inches. Please refer to the supplied documentation.

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 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 MS21069/MS21070 series nutplates are fixed self-locking, two-lug, reduced rivet spacing low height miniature anchor nuts.  MS21069 series nutplates are made from cadmium plated steel while those of MS21070 series from corrosion resistant steel (CRES). They come in different Unified Thread sizes with plain or countersunk rivet holes on each side,  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.
