Chinese Anchor nuts (also known as nutplates or anchor plates) are terms used interchangeably and relate to stamped sheet metal fasteners 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. Usually riveted to a workpiece they have an internally threaded tube and a plate with two clearance holes for rivets. 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. After placing a floating anchor nut in the correct place, rivets can be driven through the holes so that it stays in place. A threaded rod can then be inserted into the floating anchor nut even if this is slightly off-center. The built-in nut will move around slightly, making it easier to connect the threaded rod to a floating anchor nut. 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.

Anchor nuts are offered as OEM or our own brand(HAOSHENG YFN FASTENER) product lines. Sourced from quality manufacturers, HAOSHENG YFN FASTENER nutplates are intended as cost-effective alternatives to respective parts of OEM brands. They include an extensive range of  Fixed and Floating nutplates manufactured from different materials (such as steel or CRES & finishes) in accordance with military or industrial specifications and offered 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.

On the basis of 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 are 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 respective product presentation, the supplied documentation or contact us.

1、 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.

2、 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.

3、 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.
