Williams Tools JHWWS1171SCA 11-pc Combination Wrench Set

Product Description

The WILLIAMS TOOLS JHWWS1171SCA is an 11-piece 12-point SuperCombo combination wrench set covering sizes 3/8 inch through 1 inch in chrome finish. The set features two distinct engineered end designs working together: the SuperCombo open end uses machined grooves to redirect wrenching force away from fastener corners, and the SuperTorque box end applies force to the flat surfaces behind the points rather than the corners themselves. This geometry allows higher torque application without rounding or deforming hex fastener points. The set meets aerospace specification AS 954 for 12-point fasteners as defined by AS 870, making it suitable for precision torque-to-tension applications. Technicians across mechanical, industrial, and facility maintenance trades rely on sets like this for both standard and precision fastener work.

This wrench set is built for professional use in environments where fastener integrity matters, including industrial maintenance, aerospace-adjacent mechanical work, and heavy equipment service. Because the box and open end openings are identical in size on each wrench, technicians can flip between ends without changing tools mid-task. The set also functions on all common 6-point hex fasteners, providing an advantage over conventional box end wrenches in terms of flexibility and reduced fastener damage risk across a broad range of applications.

Key Features

• 11 wrenches included: 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7/8, 15/16, and 1 inch
• SuperCombo open end directs wrenching force away from fastener corners via engineered grooves
• SuperTorque 12-point box end contacts flat surfaces behind points, reducing rounding and deformation under high torque
• Meets or exceeds aerospace specification AS 954 for 12-point fasteners as defined by AS 870
• Compatible with all common 6-point hex fasteners, not limited to 12-point applications
• Box end and open end openings are identical sizes on each wrench for reversible use

Compatibility

Designed as a general-purpose combination wrench set suitable for use on standard SAE hex fasteners ranging from 3/8 inch to 1 inch across industrial, mechanical, and maintenance applications.

Installation Notes

This set is intended for use by qualified mechanical, industrial, or maintenance technicians familiar with hand tool safety and fastener torque practices. Always select the correct wrench size for the fastener before applying force to avoid tool or fastener damage. Inspect wrench openings for wear or deformation before each use, and do not use extension bars or cheater pipes on combination wrenches not rated for such use. Follow applicable industry or facility safety codes when performing torque-critical fastener work.
