Williams Tools JHWWS1171BSC 11-pc Combination Wrench Set

Product Description

The WILLIAMS TOOLS JHWWS1171BSC is an 11-piece combination wrench set designed for professional-grade fastener work in mechanical, industrial, and trade service environments. The set spans 3/8 inch through 1 inch in SAE sizing across 11 wrenches. Each wrench features a 12-point SuperCombo box end with a SuperTorque opening design that places wrenching forces on the flat surfaces of the fastener rather than the corners. This approach reduces the risk of rounding or deforming hex fasteners under high torque. The open end incorporates specially designed grooves that direct wrench force away from fastener corners. Licensed tradespeople and industrial mechanics working on structural fasteners, machinery, and mechanical assemblies will find this set directly applicable to demanding service work.

This wrench set is suited for residential and commercial mechanical service, industrial maintenance, and equipment installation where SAE fasteners in the 3/8 inch to 1 inch range are common. The identical box and open end openings provide consistent sizing without switching tools. The set meets or exceeds aerospace specification AS 954 for 12-point fasteners as defined by AS 870, making it appropriate for precision torque applications. It is also compatible with standard 6-point hex fasteners, offering an advantage over conventional box end wrenches in terms of both flexibility and economy across common trade applications.

Installation Notes

This wrench set is a hand tool intended for use by mechanics, tradespeople, and service technicians working on mechanical fasteners. No power source or lockout procedure is required for the tools themselves, but always follow applicable lockout/tagout procedures on the equipment being serviced. Select the correctly sized wrench for each fastener to avoid damage to the tool or fastener. Do not use extension bars or cheater pipes on combination wrench handles beyond their intended design.
