Osculati DIN 6798 serrated lock washers are manufactured from AISI 316 stainless steel and feature a toothed profile designed to increase resistance to loosening in suitable threaded fastening assemblies. The serrations help grip the contact surfaces beneath compatible bolt heads or nuts, providing an additional locking effect compared with conventional flat washers. Their stainless steel construction offers corrosion resistance for appropriate marine, outdoor and mechanical applications. Available in six nominal sizes from M4 to M12, these washers are supplied in boxes containing 50, 100 or 200 pieces, depending on the selected size.

Osculati AISI 316 Stainless Steel Serrated Lock Washers DIN 6798

Osculati DIN 6798 serrated lock washers are manufactured from AISI 316 stainless steel and designed to provide additional resistance to loosening in compatible threaded fastening connections. They feature a circular profile with serrated teeth around the outer edge, as illustrated in the supplier catalogue.

The serrated construction is intended to increase grip between the washer and the adjoining fastening surfaces. When compressed beneath a bolt head or nut, the teeth help resist relative rotation and reduce the tendency of the connection to loosen under suitable operating conditions.

Unlike conventional flat washers, which are primarily used to distribute clamping forces, serrated lock washers are designed to contribute a mechanical locking effect. Their effectiveness depends on the contact materials, surface condition, applied preload and installation requirements.

AISI 316 stainless steel provides corrosion resistance for suitable marine, outdoor and general mechanical applications. These washers can be used with compatible bolts, machine screws and nuts in equipment fittings, mounting brackets and other assemblies requiring additional resistance to loosening.

The range includes six nominal fastening sizes from M4 to M12. Each version is identified by an individual Osculati part number and supplied in a specified box quantity.
