Shims for Lengthening Screw Shoulders
Spin these shims onto screw threads to extend the shoulder length.
Stainless steel shims are more corrosion resistant than spring steel shims. 316 stainless steel shims have the best corrosion resistance of our stainless steel shims.
Spring steel shims are harder and hold their shape better than stainless steel shims.
