Reviews

Used in conjunction with machine screws to attach panels to my race car. You can do this to finish with a flush attachment. Size allow for more surface are to hold panel secure. Machine head screw fits great in the recess of the washer. My racing buddies are taking notice.

Essential airplane item. Buy them by the dozen and apply liberally where screws go into fiberglass or where holes are worn out. Look and quality are great.

Hard to find CSK Stainless washers at a reasonable price and a quick delivery. Would recommend.

I wanted to keep the hardware that will attach my propeller spinner, as flush to the surface of the spinner as possible. These do the job nicely when you use a countersink and flat heat screws.

I used these washers to better secure a large fiberglass spinner. I had to use the... SS MACHINE SCREW AN507C1032R10 which have slightly larger diameter than the ID of the washer. Drilling out the washer to accommodate the screw made a perfect fit.
