Capping washers distribute pressure
to a wider surface area on the cap.
They are 1-1/4"x 2" Aluminum
(not shown)
5/16" thick, and relieved in the center.

Allowing pressure near the edges first,
giving you a better glue joint!

Basic flat or fender washers, only put
pressure near the base of the screw.
