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.
...always worked great: never had a problem with these.
Received quickly, shipped at a reasonable price with USPS first class, item is as described.
needed tool box item
Excellent quality with a nice finish
Excellent time tested company. Great price, Great product, fast shipping.
Its a dimpled washer what can I say, it fits and spreads the load, works great with fiberglass fairings where you dont want to much load in one direction that might crack the fiberglass. The product is exactly what is says it is and set up for 100 degree flush bolts.
Yes, these have a shiny stainless steel appearance.
The #6 washer is a A3236-SS-012.
