DIN6921 Hexagon Flange Bolts stainless steel

Overview

A flange bolt is different from a standard bolt. Unlike other bolts, it features a broad surface area beneath the head to render a smooth distribution of securing pressure. This wide space acts as a washer, thereby eliminating the requirement to look for an additional spare for application of such bolts.
