M27 SS Washer - 25 Nos

Stainless steel flat washers per ISO 7089 / DIN 125 Form A are thin circular discs with a central hole used to distribute clamping load, protect mating surfaces, and span oversized holes. Available in A2 and A4 grades with 200 HV or 300 HV hardness classes.

Dimension #

• All dimensions in mm, tolerance +/- 0.01 mm. Additional dimensions available on request.

Benefits #

Flat washers address several common bolted joint problems. They distribute clamping force over a larger bearing area, reducing contact pressure that can damage soft materials such as aluminium, timber, or plastic. The washer provides a smooth, hardened bearing surface for nut or bolt head rotation during tightening, preventing surface scoring and galling. In assemblies with oversized or slotted holes, flat washers bridge the gap to maintain proper load transfer. Stainless steel A2 and A4 construction eliminates coating degradation and provides consistent corrosion resistance throughout the washer thickness. For sensitive surfaces in architectural and food-grade applications, the smooth stainless finish prevents contamination and supports cleaning protocols.

Common Applications #

Stainless steel flat washers are used in nearly every bolted joint requiring load distribution or surface protection.
