Stainless Lock (split) and Flat Washers
Lock washers are surprisingly effective at stopping
screws from vibrating loose.
Buying tip: The washer size should match the first number in the
screw size. As an example, a #4 washer will fit a 4-40 Socket Head and a #4 Sheet Metal Screw, etc.
After entering the number of packages that you want for each item,
