PETOL I-beam designed STRIKING WRENCHES feature greater handle strength and the clearance in overall head diameter this is necessary when working with flange connections. 

The large smooth striking surface reduces the hazard of glancing blows and lessens the change of a rope slipping from the handle when maintaining tension on the wrench.

All PETOL Striking Wrenches are forged from alloy steel and properly heat-treated to guarantee specific Rockwell hardness for strength and maximum tool life. 

The Gearench part number, stud size, and PETOL trademark are clearly marked on the handle of each wrench.
