โ What is the difference between a 3/4 flange bolt and a standard hex bolt?
A 3/4 flange bolt has an integrated flange under the head that distributes the load like a washer, eliminating the need for a separate washer. It provides better clamp force and reduces assembly time. Our 3 300 flange bolts are designed to meet ASTM A325 and A490 specs.
