M22 Square Taper Washer for I-Sections in A2 Stainless Steel - DIN 435
Square taper washers for use with tapered flange I-section beams to EN 10024. This washer has a taper angle of 14% which corresponds to the angle or taper on the I-section's flange.
The groove is on the underside and indicates the thick end of the taper. Placed on the I section, they will create a level surface for the bolt head or nut to be fixed against. Square
taper washers will also distribute the load evenly around the fixing point and reduce the risk of the joint loosening.
