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
