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 common in ships engineering 
						plants: 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, thus giving precise torque. Striking wrenches 
						also provide shock and high force used to release large 
						and/or stuck nuts and bolts; and when space does not 
						allow room for a large wrench. Slugging wrenches were 
						primarily keep in the Repair Station Five the 
						Englineering Repair Station for emergency repairs to the 
						ships engineering plant.  |
