Hex Head Cap Screws Plated

Hex head cap screws are manufactured to dimensional standards of ASME B18.2.1 and to various material and mechanical standards of ASTM and SAE. The length of a cap screw is measured from under the head to the extreme end of the screw. The standard thread length is two times the diameter plus 1/4" up to 6" length and two times the diameter plus 1/2" for screws longer than 6". Shorter length screws are fully threaded. Product standards require the manufacturer's head marking to appear on the top of all hex cap screws 1/4" diameter and larger.
