Overview
These Tekno RC flat washers have an M4 bore and a 9mm outside diameter in a plain, unfinished look. They are the washer you reach for whenever an M4 screw needs a wider, flatter surface to pull against than the part itself can provide.
Sitting under a screw head, a washer this size spreads the clamping load out instead of concentrating it in a small ring. That keeps composite parts from being crushed or marked, and it makes the clamping force you apply far more consistent from one build to the next. Sold as a bag of ten.
