What is the Difference Between a Bolt and Screw ?

If you are buying bulk bolts it is useful to know what a bolt is … so let’s have a lesson in fasteners and understand the difference between a bolt and a screw. The answer is simple, a bolt is designed to be tightened by a nut and a screw is designed to be tightened by rotating the head. Bolts and screws can sometimes be difficult to tell apart, for instance common “hex head bolts” are truly “hex head cap screws”.  The difference is that hex head cap screws feature a raised “washer face” beneath the head which prevents the hex corners from contacting the mating part as the head is rotated.
