Williams Comfort Products JHW1242B Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1242B is a 1 5/16 inch combination wrench designed for high-torque fastening work in industrial and professional trade environments. It features a SUPERTORQUE box end and a SUPERCOMBO open end, both engineered to apply wrenching force to the flat surfaces of hex fasteners rather than the corners. This reduces rounding and deformation on hex points, making it a reliable choice for mechanics, millwrights, and maintenance technicians who work with critical fasteners. The box and open end openings are identical in size, providing consistent fit across both ends of the wrench.

This combination wrench is suited for industrial maintenance, mechanical assembly, and precision fastener applications where torque accuracy matters. The SUPERTORQUE box end meets aerospace specification AS 954 for 12-point fasteners as defined by AS 870, making it appropriate for applications requiring a precise torque-to-tension relationship. The SUPERCOMBO open end works on all common 6-point hex fasteners and offers a practical advantage over conventional open-end designs in tight or repetitive-use scenarios. The industrial black finish adds corrosion resistance for shop and field use.

Key Features

• SUPERTORQUE box end applies force to flat fastener surfaces, not corners, reducing rounding and deformation
• SUPERCOMBO open end uses specially designed grooves to redirect wrench force away from fastener corners
• Meets aerospace specification AS 954 for 12-point fasteners as defined by AS 870
• Compatible with all common 6-point hex fasteners, offering flexibility over standard box end wrenches
• Box and open end openings are identical at 1 5/16 inches for consistent fitment on both ends
• Industrial black finish; conforms to ANSI B107.6 and SAE AS 954

Compatibility

Designed for use with standard 6-point and 12-point hex fasteners with a 1 5/16 inch opening, suitable for industrial maintenance and mechanical assembly applications.

Installation Notes

This wrench is installed and used by mechanics, millwrights, and general maintenance technicians. Always ensure the wrench opening is fully seated on the fastener before applying torque. Power down and de-energize any equipment before servicing fastened assemblies on electrical or mechanical systems. Do not use extension bars or cheater pipes to increase leverage beyond the tool's rated capacity.
