Taper washers are machined or pressed with a sloped face to seat square against the tapered flange of a channel, I-beam or joist, so the bolt is loaded axially rather than being bent across the flange angle.
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.
