Osculati AISI 316 Stainless Steel Flat Washers DIN 125 / UNI 6592

Osculati flat washers are manufactured from AISI 316 stainless steel and are listed according to DIN 125 / UNI 6592. These washers feature a flat, circular design with a central hole for use with compatible metric bolts, machine screws and threaded fasteners.

Installed beneath a bolt head or nut, a flat washer helps distribute the clamping force over a larger bearing area. This can help reduce localized pressure on the mounting surface and provide a suitable contact surface for the fastening assembly.

Unlike spring washers or self-locking nuts, standard DIN 125 flat washers do not incorporate a dedicated locking mechanism. They are intended primarily for load distribution and spacing in compatible mechanical connections.

AISI 316 stainless steel provides corrosion resistance for suitable marine, outdoor and general mechanical applications. These washers can be used with compatible deck fittings, mounting brackets, equipment components and other threaded assemblies.

The range includes seven nominal fastening sizes from M3 to M12. Each variant is identified by an individual Osculati part number and supplied in a box containing a specified number of washers.
