Type B washers also feature outside diameters that are narrow, regular or wide. If you only have one flat washer per bolt, and if the material next to the bolt head is sufficiently hard to resist deformation, then the one flat washer should be on the nut side. These washers can either have a plain finish or can be hot dipped galvanized. threaded washer Gewindescheibe {f} thrust washer Anlaufscheibe {f}tech. This extra strong safety washer has a greater thickness for higher pre-tensioning loads. 0 They are typically designed to spread the loan and protect the respective surface from damage. The most common type of washer, with two flat surfaces: Round or square: Used to distribute force/stress of a nut or bolt and reduces friction and heat during installation of threaded fastener: Sealing: Made of relatively soft materials: Round: Forms a seal around a bolt or fastener and sometimes bonds to metallic washers: Slotted Spring lock washer for screws with cylindrical heads37200 • Spring lock washers acc.
