Description of the hex flange screw

    The Hex head flange bolts are flanged hex head bolts or screws and are a similar addition to DIN 931 and DIN 933. They are a more attractive alternative and do not require a washer, because the area under the bolt head is wider and creates a larger area for even distribution of pressure. Manufactured in accordance with DIN 6721, manufactured in full thread, a small amount may be partially threaded
