Williams JHW1228SC Combination Wrench 7/8 Inch 12 Point

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1228SC is a combination wrench with a 7/8 inch opening, featuring a SUPERCOMBO open end and a SUPERTORQUE 12-point box end. The wrench measures 12.5 inches in overall length and weighs 0.957 pounds. It carries a high-polish chrome finish and meets ANSI B107.6 and SAE AS 954 aerospace specifications for 12-point fasteners. Licensed trade professionals and industrial maintenance technicians rely on this tool for precision fastener work where torque control and fastener preservation are critical requirements.

This wrench suits a wide range of applications in HVAC, plumbing, electrical, and general mechanical service. The SUPERCOMBO open end directs wrench force away from fastener corners to reduce rounding on worn or tight hardware. The SUPERTORQUE box end applies wrenching force to the flat surfaces behind fastener points rather than on the corners themselves, making it effective on both standard 6-point and 12-point hex fasteners in tight or high-torque service environments.

Key Features

• SUPERCOMBO open end uses specially designed grooves to direct force away from fastener corners
• SUPERTORQUE 12-point box end contacts flat surfaces behind fastener points, reducing deformation risk
• Box and open end openings are identical at 7/8 inch, reducing tool changeovers
• Meets or exceeds aerospace specification SAE AS 954 and ANSI B107.6
• Compatible with all common 6-point hex fasteners with performance advantage over conventional box end wrenches
• High-polish chrome finish for corrosion resistance and durability

Compatibility

Designed as an OEM-style replacement and standard service wrench for 7/8 inch 12-point and 6-point hex fasteners across residential and commercial trade applications.

Installation Notes

This combination wrench is a hand tool intended for use by qualified trade professionals in mechanical, HVAC, plumbing, and electrical service. Always select the correct opening size before applying torque to avoid fastener damage. Ensure the wrench is fully seated on the fastener before applying force. Inspect the tool for cracks or wear before use and do not use extension bars on the handle unless the tool is rated for such use.
