2-7/16" 12-point striking wrench
The Gray Tools 66878 is a 2-7/16 inch 12-point striking face box wrench with a 45 degree offset head. Forged from premium tool steel, it features a corrosion resistant black oxide finish and precision broached jaws for a secure fit. A large striking block provides maximum safety and surface contact during impact use. It meets ANSI standards for hand tools.
Verify fastener size and clearance
Before ordering, confirm the fastener requires a 2-7/16 inch 12-point opening and that the 45 degree offset head can access the bolt location. Ensure adequate swing room exists for a striking wrench and that a hammer or mallet is available for impact applications. Check that the black oxide finish suits the working environment.
Heavy-duty impact tightening and loosening
This wrench fits into maintenance and construction kits where high torque on large fasteners is needed without powered equipment. The offset head clears obstructions around the bolt, while the striking block transfers hammer blows directly to the fastener. The robust steel construction withstands repeated impact, freeing the user from hydraulic or pneumatic tools in remote or confined areas.
