Square Head Bolts are similar to Hex Cap screws but have a 4 sided square head instead of a 6 sided hexagonal head. The square head enables an easier wrench grip for tightening and a larger bearing area for gripping. 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. Hot Dip Galvanized fasteners are extremely corrosion resistant and often used in long lasting, outdoor applications.
