Brass nuts for mounting of aircraft instruments from the front of the panel.
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.

Nuts are extensively used in a wide range of aerospace and industrial applications. Self-locking nuts are those containing a locking feature as an integral part.
Hexagon self-locking nuts of both low (thin pattern) and regular height (pattern) used in aerospace and defense applications comform to different Standards and they are designed for use in high temp installations (up to 250°F or 1200°F for those from silver-plated stainless steel). Low height self-locking nuts complied with Army & Navy AN 364 superseded by Mil Standard MS 20364 which was in turn superseded by the newer Mil Standard MS 21083. Similarly, Army & Navy AN 365 Standard relating to regular height nuts was superseded by Mil Standard MS 20365 and this in turn by MS21044. Furthermore, MS Standards have been replaced by NASM National Aerospace Standards with their part identification numbers remaining the same. For example, nuts with PNs MS21083 and NASM21083 are identical.
Regular height NASM/MS 21044 self-locking nuts and their low-height NASM/MS 21083 counterparts replace the superseeded MS 20365 / AN 365 & MS 20364 / AN 364 for respective materials and sizes but their older Standard part numbers (although cancelled) are still commonly used in the market. Sourced from quality manufacturers, these nuts are offered as part of own labelled (AVIATIONEU NEW ERA) product lines in different materials and finishes (e.g. cadmium plated alloy steel, corrosion resistant steel passivated,copper cadmium plated, aluminum alloy anodized), and different dimensions and thread sizes in inches.

Titanium fasteners are best known for their strength, lightweight, and corrosion resistance. They feature an excellent strength to weight ratio and significant mechanical properties but perhaps their most notable attribute is their superior corrosion resistance to salt water / seawater operating conditions. Titanium fasteners are used in aerospace, automotive and motorsports but also in many other industries including chlor alkali, marine, off-shore oil & gas, desalination, medical, and pulp and paper. They come in different types (like bolts, screws and nuts), sizes, titanium grades and standards/specifications (e.g. ANSI/ASME, DIN/ISO, ASTM, ASME, MIL specifications etc.) to meet application requirements. Compared to respective fasteners made of steel and aluminum, as a rule of thumb, titanium fasteners are about half the weight of their steel counterparts while aluminum fasteners are about half the weight of titanium ones.
Sourced from quality producers, a wide range of titanium fasteners are offered as part of AVIATIONEU NEW ERA product lines (please refer to the individual product presentations).
AVIATIONEU NEW ERA Titanium nuts are available in both inch and metric systems. Their typicals uses include aerospace, marine, motorsports and many other applications.

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.

The NAS1423/NAS509 series hexagon nuts fall into the jam (aka check or thin) nut category. Jam nuts are a style of nut that features a low profile, typically half the height of standard nuts and diagonal drilled holes. Their minimal thickness allows them to fit in tight spaces where ordinary nuts might not fit. NAS1423 series jam nuts are manufactured from 4130/4340 cadmium plated steel alloy or unplated A 286 stainless steel (designated by the letter "C" in the part number). NAS509 series jam nuts NAS1423 series jam nuts are manufactured from 4130/4340 cadmium plated steel alloy or corrosion resistant steel passivated (designated by the letter "C" in the part number).
Sourced from quality producers, the NAS1423/NAS509 Series check nuts are offered as part of our own label (AVIATIONEU NEW ERA) product lines with Right or Left Hand threads in different sizes in inches. Letters "R" and "L" in the end of the product reference number (SKU) indicate a Right or Left Hand thread respectively. Sold in pieces or packs of specified nuts per pack indicated after the letters "PK" in the product reference number (SKU).

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.
