When you’re designing bolted joints, always use a washer under the head of the bolt to prevent galling between the bolt head and the material you’re bolting down. Get psyched: McMaster sells the washers you want as “Spring Steel Shims for Shortening Screw Shoulders.”

Use regularly for Grade 2 hex cap screws and high strength alloy steel for Grade 5 and 8 hex cap screws. Tooth lock washers—internal, external, internal-external, and countersunk external—create a ratchet action by biting into the nut or screw head and the surface it contacts

Length is measured from the point at which the head sits flat with the surface, to the tip of the threads. Hex, pan, truss, button, socket cap, and round head screws are measured from right under the head to the end of the threads.
