Anchor nuts (aka nut plates or anchor plates) are stamped sheet metal fasteners used in blind mounted panel applications, where hex nuts cannot be used or an attached nut is required for ease of maintenance. They are usually riveted to a workpiece and have an internally threaded tube and a plate with two clearance holes for rivets. These terms are used interchangeably to describe the respective fasteners.
Sourced from quality manufacturers,anchor nuts are offered either as part of AVIATIONEU NEW ERA product portfolio or as OEM products . They come in Fixed or Floating types, different materials & finishes (*), single/double lug versions, Metric (M3 - M12) οr Unified thread sizes (**) and meet military or industrial specifications (***). Genrally sold in pieces but packs are also used. In the case of packs, the specified number of anchor nuts per pack is indicated after the letters "PK" in our product reference number (SKU). Appearing prices are always for the units of measurement used each time.
(*) INCONEL alloy, CRES A-286 alloy, C1050 heat treated carbon steel or other steel alloys depending on the supplier.
INCONEL is a registered trademark of Special Metals Corporation for a family of austenitic nickel-chromium-based superalloys. They belong to the family of austenitic nickel-chromium-based superalloys, oxidation-corrosion-resistant materials well suited for service in extreme environments subjected to pressure and heat.
CRES A-286 alloy is iron-nickel-chromium based austenitic iron based material with additions of molybdenum and titanium known for its good strength and oxidation resistance especially at temperatures up to 1300°F (700°C). It is used in various components, such as aircraft and industrial gas turbines due to is high strength and superior fabrication. Alloy A286 characteristics include good machinability and oxidation resistance up to 800°C, very high corrosion resistance, high mechanical properties and strengths well retained up to 700°C and others.
(**) Metric ISO thread (M ) standard in Europe. Designated by the letter M followed by the value of the nominal diameter (the max thread diameter) and the pitch separated by the sign “x”, both expressed in millimetres. Unified form thread designations, such as UNC (unified coarse) or UNF (unified fine), have a fixed number of threads per inch with the thread major diameter preceding the designation (e.g. 9/16”UNC or 9/16”UNF). UNC is the most commonly used for general purpose applications but UNF threads have a slightly higher breaking load capacity than the UNC.
(***) There is currently no military specification for Metric nut plates.
