The square, external wrenching head found on a square head bolt offers a large bearing area for positive gripping. At one time, square head bolts (aka square bolts) were the industry standard before being replaced by hex head bolts. Now, they are commonly chosen for aesthetic reasons to create a rustic look in new buildings or to match existing fasteners in an old building.

Our square head bolts are available in plain, zinc, and hot dipped galvanized – which offers the most corrosion-resistance for harsh environments.
