Portland Bolt manufactures custom square bend hook bolts from 1/2 to 1-1/2″ diameter to virtually any ASTM specification. Hook bolts are provided either plain finish or hot-dip galvanized. Stainless steel hook bolts are also manufactured. All operations, including the galvanizing process, are performed in-house.

Hook bolts can be either square or round bend. See our bending capabilities page for more information about how bent bolts are made and what kinds of bent bolts we can provide.

Square hook bolts are typically dimensioned as follows:
