What is the difference between an allen bolt and a hex bolt?
An allen bolt (socket head cap screw) has a round head tightened with an allen key from inside. A hex bolt has a six-sided head tightened with a spanner from outside. Allen bolts suit tight spaces and machinery; hex bolts suit general and structural work.
