At Baseline Bolt, we manufacture custom square bend hook bolts of diameter 1/2 to 1-1/2″ to generally fulfill any ASTM specification. These bolts come in both plain finish and hot-dip galvanized finish. We also manufacture stainless steel hook bolts. All our operations are done in-house.


Square hook bolts are typically dimensioned as follows:

Diameter (D) x Length (L) x Hook width (C) x Hook length (A) x Thread (T)
