Flange Bolt Hex Head (Unserrated) M20 x 50mm in Bright Zinc Plate 8.8 - DIN 6921

The DIN 6721 flange bolt is a hexagon headed bolt or screw incorporating a flange, negating the need for a washer. Flange bolts are a more attractive alternative to their DIN 931 and DIN 933 hex driven counterparts. Typically used where The flange offers protection for the bolted component where the driving tool may otherwise scratch its surface. Generally manufactured with a full thread, though occasionally some stock may include a partially threaded shank. This variant is plain, unserrated under the head. ISO 4162 and EN 1665 are similar standards but with some dimensional differences.
