DIN 462 Roofing Lock Washer with Internal Lug

The DIN 462 roofing lock washer with internal lug is designed for use together with the DIN 1804 slotted nut, as well as with other threaded fasteners. Its main application is fastening roofing materials. The product is made of alloy steel with a zinc-plated coating, austenitic alloys, copper, and brass. It is shaped as a ring with a small lug on its inner surface for engagement with the recess in the head of the main fastener.

The lug in the design of the DIN 462 washer allows it to function as a locking element. It engages firmly with the head of the threaded fastener or nut, preventing it from loosening even under strong dynamic loads.

The corrosion-resistant coating allows the fastener to be used in conditions of high humidity and aggressive environments. This is important during construction and installation work, in particular when building a roof.
