Overview
Countersunk washers give a flat-head screw a proper conical seat to pull against, which is exactly what you want when that screw passes through a composite or soft aluminum part. These Tekno RC M3 washers are machined from aluminum and left in a natural finish, and they arrive as a bag of ten.
Used under M3 flat-head hardware, they spread the clamping load over a wider area and keep the screw head from burying itself into the part beneath it. That means a more consistent clamp, cleaner looking hardware and less wear on the components you are bolting together.
