DIAMOND ENGINEERING Washer Flange 5/16×1.00 DE5376HP

This system cleans up the stamped flat edge and stepped look of standard flat washers when used with Race Proof 12 Point flange bolt, A precision counterbored hole is CNC-machined for the bolt to sit down inside of the washer – when the bolt is installed in the washer the two flanges meet for an almost seamless look, All washers also feature a tight tolerance hole with an i.d. chamfer to clear the large under-head radius on Race Proof bolts, Made in the U.S.A.
