Williams Comfort Products JHW1178AB Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1178AB is a combination wrench with a 1 9/16 inch opening designed for heavy-duty fastening work in industrial and mechanical applications. It features a SUPERTORQUE 12-point box end and a SUPERCOMBO open end, both ground to the same opening size. The box end applies wrenching force to the flat surfaces of hex fasteners rather than the corners, reducing the risk of rounding or deforming fastener points. The open end uses specially designed grooves to redirect force away from corners as well. This wrench carries an industrial black finish and meets ANSI B107.6 and SAE AS 954 specifications.

This wrench is suited for industrial maintenance, assembly, and repair environments where precise torque application is required. The 12-point box end meets aerospace specification AS 954, making it appropriate for precision fastening tasks. The identical box and open end openings provide consistent sizing across both ends, which simplifies tool selection during service work. Mechanics, millwrights, and industrial technicians working with large hex fasteners will find this tool appropriate for high-torque applications where fastener integrity must be preserved.

Key Features

• SUPERTORQUE 12-point box end contacts flat fastener surfaces, not corners, reducing rounding risk under high torque
• SUPERCOMBO open end uses grooved geometry to redirect wrenching force away from fastener corners
• Box and open end openings are the same size at 1 9/16 inches for consistent fitment
• Meets or exceeds aerospace specification SAE AS 954 for 12-point fasteners as defined by AS 870
• Complies with ANSI B107.6 federal specification
• Industrial black finish for corrosion resistance in shop and field environments

Compatibility

Designed for use on standard 6-point and 12-point hex fasteners with a 1 9/16 inch across-flats dimension. Compatible with common hex fastener types found in industrial, mechanical, and aerospace assembly applications.

Installation Notes

This wrench is a hand tool intended for use by mechanics, millwrights, and industrial technicians. Ensure the correct opening size is matched to the fastener before applying torque to avoid slippage. Do not use extension bars or cheater pipes on combination wrenches, as this can exceed rated tool capacity and damage fasteners. Follow applicable torque specifications for the fastener and joint type being serviced.
