DIN LN 29679 / LN 29693...
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 offered as part of ΟΕΜ manufacturers (such as PAOLO ASTORI) or our own labelled (AVIATIONEU NEW ERA) product lines in different metric sizes, materials and finishes. Those of DIN LN29679 Series relate to self locking floating two-lug low profile anchor nuts made from 25CrMo4 Alloy Structural Steel and can withstand temparatures up to 235 °C. Their counterparts in DIN LN29693 (*) Series are made from Incoloy Alloy® A-286 (also known as A286 Alloy Stainless Steel, a nickel and iron-based, austenitic superalloy) and can be used for temperatures up to 425 °C. Both are 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.
(*)LN 29693:2015-05 Standard for Aerospace - Nuts, plate, self-locking, floating, two lugs, for temperatures up to 425 °C is inactive for new design.
