5/16"-18 Grade 5 Serrated Hex Flange Bolt

Serrated Hex Washer Head Flange Bolt:  This is an un-slotted hex-washer face bolt, but with a thicker flange and serrations on the bearing surface side.  Flange bolts are used in applications where loosening is possible due to stresses such as vibration.  The serrations grip to the bearing surface so more torque is needed to loosen them than to tighten the bolt.  The flange also provides more strength than a standard bolt and eliminates the need for a lock washer or locknut.  The length of a hex bolt is determined by measuring from under the head of the bolt to the base of the threads.
