Combined Drive 40mm Stainless Steel Machine Screws , Serrated Hex Flange Bolt
1. Description:
Flange screws and hex serrated flange bolts are available in two styles and a wide range of sizes and lengths.
A flange screw with a serrated hex washer is an un-slotted hex head screw style with a unified thread pitch, and a flange that has serrations on the bearing surface side. These screws are designed for use in applications where vibrations can loosen fasteners. The serrations grip the bearing surface so that significantly more torque is needed to loosen the screw than it does to tighten it. The flange provides more strength than a standard machine screw and eliminates the need for a lockwasher or locknut in certain applications.
