Williams Comfort Products JHW1198BBL Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1198BBL is a combination wrench with a 2.875 inch opening, featuring both an open end and a box end on a single tool. The open end uses a SUPERCOMBO design with machined grooves that shift wrenching force away from fastener corners, reducing the risk of rounding. The box end uses a SUPERTORQUE 12-point profile that contacts the flat surfaces behind the fastener points rather than the corners themselves, allowing higher torque application without deforming the fastener. The satin-chrome finish provides corrosion resistance and clean appearance. This wrench is intended for use by maintenance technicians, industrial tradespeople, and mechanical contractors working on heavy equipment and structural fasteners.

This combination wrench is suited for industrial, commercial, and heavy-duty maintenance applications where fastener integrity is critical. The 2.875 inch opening accommodates large hex fasteners commonly found in heavy mechanical assemblies, structural connections, and equipment frames. Both the open end and box end openings are identical in size, making either end interchangeable for the same fastener without switching tools. The SUPERTORQUE box end meets aerospace specification AS 954 for 12-point fasteners as defined by AS 870, making it appropriate for precision torque applications where accurate torque-to-tension relationships are required.

Installation Notes

This wrench is installed and operated by hand without power tools. Before applying torque to any fastener, ensure the correct end and proper seating of the wrench on the fastener to prevent slippage. Follow applicable equipment service specifications and torque requirements for the fastener being serviced. Inspect the wrench for cracks or wear before each use and do not use extension bars or cheater pipes on combination wrenches unless specifically rated for such use.
