Standard and Metric Flange Bolt Sizes

Flange bolts are widely available in a variety of sizes, materials and finishes.  They may be supplied with a smooth washer face, or one with serrations on the underside which grip into the mated surface, thereby reducing the need for a lockwasher or other locking element to prevent loosening.

Automotive Flange Bolts & Other Industry Applications

Flange Bolts are used extensively in the automotive industry, industrial machinery, plumbing, and in a variety of diverse applications.  In the fastener industry, their unslotted hex head has a built-in washer flange underneath which serves to broaden the bearing surface to the mated material.  This not only offers a smooth distribution of pressure, but also reduces the potential of damage to the material surface itself.
