Williams Tools JHWWS1170SCA 7 Pc Combo Wrench Set

Product Description

The WILLIAMS TOOLS JHWWS1170SCA is a 7-piece 12-point SuperCombo combination wrench set covering sizes 3/8 inch through 3/4 inch in a chrome finish. The set pairs a SuperCombo open end with a SuperTorque box end on each wrench. The open end features specially designed grooves that redirect wrenching force away from fastener corners, reducing the risk of rounding. The box end applies torque to the flat surfaces behind the fastener points rather than the corners, allowing higher torque without deforming the fastener. Both box and open end openings are identical in size on each wrench. Licensed trades and industrial mechanics reach for this set when fastener access or torque demands exceed what a standard combination wrench delivers.

This set is suited for mechanical and industrial applications where both 6-point and 12-point fasteners are encountered. The 12-point box end meets aerospace specification AS 954 for 12-point fasteners as defined by AS 870, providing an accurate torque-to-tension relationship for precision work. The set is also compatible with common 6-point hex fasteners, offering a measurable advantage over conventional box end wrenches for technicians who want a single set that handles a broad range of fastener types on the bench or in the field.

Installation Notes

Select the correct wrench size before applying torque to avoid fastener damage. Always ensure the wrench is fully seated on the fastener before loading. Follow applicable industry torque specifications for the fastener and joint type. De-energize or depressurize any system before breaking loose fasteners on live mechanical assemblies.
