Williams Comfort Products JHW1199B Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1199B is a combination wrench with a 3 3/8 inch opening, designed for professional fastener work in demanding trade and industrial environments. It features both a SUPERCOMBO open end and a SUPERTORQUE box end on the same tool, with both openings sized identically. The SUPERTORQUE box end applies wrenching force to the flat surfaces of hex fasteners rather than the corners, allowing higher torque without rounding or deforming fastener points. The SUPERCOMBO open end uses specially designed grooves to direct force away from fastener corners as well. The satin-chrome finish resists corrosion and reduces glare. This wrench meets ANSI B107.6 and SAE AS 954 specifications.

The JHW1199B is suited for mechanical, industrial, and heavy-trade applications where fastener integrity and torque accuracy matter. It works on all common 6-point hex fasteners and meets aerospace specification AS 954 for 12-point fasteners as defined by AS 870, making it a reliable choice for precision torque applications. Electricians, pipefitters, millwrights, and general mechanical contractors will find this wrench useful on the bench or in the field where larger fasteners are common.

Key Features

• SUPERTORQUE box end applies force to flat fastener surfaces, not corners, reducing rounding and deformation under high torque
• SUPERCOMBO open end uses directional grooves to keep wrenching force off fastener corners
• Box and open end openings are the same size for consistent fitment on both sides
• Meets ANSI B107.6 and SAE AS 954 specifications, including aerospace-grade requirements for 12-point fasteners
• Compatible with all common 6-point hex fasteners with performance advantages over standard box end wrenches
• Satin-chrome finish for corrosion resistance and reduced surface glare

Compatibility

Designed for use on all common 6-point hex fasteners and 12-point fasteners meeting AS 870 definitions. Both the box end and open end share a 3 3/8 inch opening for interchangeable use across fastener types.

Installation Notes

This wrench is installed by hand and requires no power tools or specialty equipment. Before use on fasteners in pressurized or energized systems, follow all applicable lockout/tagout procedures and relevant code requirements including NFPA 70E for electrical work or OSHA 1910.147 for general industry. Do not use extension bars or cheater pipes on this wrench to exceed its rated capacity. Inspect the wrench for cracks or deformation before each use.
