A plate nut, also known as a nut plate, anchor nut or anchor plate, is a stamped sheet metal nut that is usually riveted to a workpiece. These terms are used interchangeably throughout product presentations to describe respective products.
Anchor nuts have a long tube that is internally threaded and a plate with two clearance holes for rivets. They are self-locking nuts resisting loosening under vibrations and torque. They offered in fixed, floating, miniature and countersunk body, versions and one-lug, two-lug, short-lug, corner or right angle body configurations. Unlike fixed anchor nuts, their floating counterparts have a built-in nut that can move slightly to align with the threaded rod. This floating version provides flexibility when installing the bolt or screw.
Anchor nuts in Metric system for aerospace applications are available in different metric sizes, materials and finishes. Those of DIN LN29673 Series relate to self locking one-lug anchor nuts offered by different manufacturers such as HOWMET AEROSPACE (ARCONIC) or PAOLO ASTORI. Sold mostly in pieces but also in packs where the number of anchor nuts per pack is indicated after the letters "PK" in the product SKU.
