This is a specialized thick / short / stocky wrench with a block end to the handle specifically designed for use with a hammer enabling one to impart great force. Used commonly with large fasteners - especially a nut and stud which both have index marks: the nut is screwed hand-tight then further tightened with the striking wrench a known number of index marks calculated from the elasticity of the bolt or stud giving precise torque. Striking wrenches also provide shock and high force used to release large and / or stuck nuts and bolts where space does not allow room for a large wrench.
