Hex Washer Head Flange Bolt: This is a one-piece hex-washer head bolt with a flat bearing surface, made of high-alloy steel, face bolt, but with a thick flange bearing surface side. The flange provides more strength than a standard bolt and eliminates the need for a lock washer or lock nut. For use on truck frames with Grade 8 Flange Top Lock Nuts. The length of a hex bolt is determined by measuring from under the head of the bolt to the base of the threads.
