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. Sold in pieces or packs of specified number of anchor nuts per pack indicated after the letters "PK" in the product SKU.

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.

NAS 577 Standard specifies the dimensional and material requirements for a specific type of self-locking nut, which is designed with a built-in locking mechanism to resist loosening under vibration or other dynamic loads, unlike a standard, non-locking nuts which rely solely on the friction between the threads of the nut and bolt, and the clamping force generated by tightening, to prevent loosening.  

Barrel nuts are used in different fastening applications as an alternative to traditional nuts. Due to their their aesthetically pleasing finish, barrel nuts are particularly common in furniture as connectors but also in aerospace manufacturing in aircraft landing gear and other components. Since their original form as a round bar stock with a transverse tapped hole their design has undergone many refinements with the elimination of material not contributing to their performance, the addition of a thread-locking option or a floating nut element to compensate for hole misalignment and so on. 

Today NAS 577 Standard barrel nuts are produced by different manufacurers, such as HOWMET AEROSPACE (formerly ARCONIC) PAOLO ASTORI, or PCC SHUR-LOK. They are used in various aerospace and industrial applications requiring a secure and reliable, high strength fastening with resistance to fatigue failure.
