Hex washer head bolts with external machine screw threads, a circular flange, and a smooth (non-serrated) bearing surface, DIN 6921 Hex Flange Bolts are hex washer head bolts with external machine screw threads, a circular flange, and a smooth (non-serrated) bearing surface; the flange flares to a diameter that is larger than the hex top section. The integrated head flange distributes clamping force across a broader surface, allowing use with uneven, misaligned, and oversized holes. Flange bolts are frequently used in conjunction with flange nuts. There are steel grades 8.8 and 10.9, as well as stainless steel, available. Zinc plating and plain finishes (no surface treatment to prevent rust) are prevalent for steel. Thread tolerance is 6g for plain finish steel and stainless steel, and 6h for plated steel; right-hand threads are standard.
