M8-1.25 hex flange bolts in 18-8 stainless steel to DIN 6921. A hex flange bolt — also called a frame bolt — carries an integral flange under the head that spreads the clamp load across a wider bearing area, exactly as a separate washer would, so the joint needs one fewer part to handle and install. The flange face is smooth rather than serrated, which suits finished or soft surfaces you do not want marked. Common in machine frames, brackets, automotive assembly and general equipment build. Fully threaded. 4 lengths (16mm to 40mm). Sold in production-volume bulk packs.
