Plain washers spread the bearing load of the nut or bolt head over a larger area, protecting the surface and preventing the fastener from pulling into softer material. Supplied to DIN 125, DIN 9021 and ASTM dimensions.
Supplied in bulk to distributors, importers and hardware brands worldwide, including private-label packaging in the customer's own branding. Non-standard sizes and made-to-drawing variants are produced to order, with a material test certificate on every consignment.
