SQUARE HEAD MACHINE BOLTS
Square Head Bolts are similar to Hex Cap screws but have a 4-sided square head instead of a 6-sided hexagonal head. They are commonly referred to as both bolts and screws and are designed to be driven with a wrench. Square Head Bolts are partially threaded with a shoulder beneath the head.
