    DIAMOND ENGINEERING Polished 5/16" x 1.00" Stainless Steel Flange Washer System
    • This system cleans up the stamped flat edge and stepped look of standard flat washers when used with Race Proof 12 Point flange bolt
    • Every washer is specifically engineered for each size bolt with several key design features
    • 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
    • To achieve a highly reflective finish a large radius is machined on the edge of each washer - a radius will "shine" and reflect more light than a square edge
    • Finally each washer is polished, by hand, to a perfect mirror finish
    • Washers are available for the entire range of bolt sizes from 1/4" through 7/16" in a variety of diameters; conveniently packaged two or four to a pack with 7/16" x 1.062" washers also packaged in a 5-pack for belt sprocket applications
    • Made in the U.S.A.

    DIAMOND ENGINEERING Polished 3/8" x .812" Stainless Steel Flange Washer System, 4-Pack
    • This system cleans up the stamped flat edge and stepped look of standard flat washers when used with Race Proof 12 Point flange bolt
    • Every washer is specifically engineered for each size bolt with several key design features
    • 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
    • To achieve a highly reflective finish a large radius is machined on the edge of each washer - a radius will "shine" and reflect more light than a square edge
    • Finally each washer is polished, by hand, to a perfect mirror finish
    • Washers are available for the entire range of bolt sizes from 1/4" through 7/16" in a variety of diameters; conveniently packaged two or four to a pack with 7/16" x 1.062" washers also packaged in a 5-pack for belt sprocket applications
    • Made in the U.S.A.
