Williams Comfort Products JHW1210SC Combination Wrench 5/16 in

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1210SC is a combination wrench built for precision fastener work in demanding trade environments. It features a 5/16-inch opening on both the box end and open end, with an overall length of 5.75 inches and a weight of 0.084 pounds. The SUPERTORQUE box end applies wrenching force to the flat surfaces behind hex points rather than the corners, reducing the risk of rounding or deforming fasteners. The SUPERCOMBO open end uses specially designed grooves to redirect force away from fastener corners as well. Finished in high-polish chrome, this wrench meets ANSI B107.6 and SAE AS 954 specifications.

This wrench is suited for residential and commercial mechanical, HVAC, plumbing, and general trade applications where fastener integrity matters. The matching 5/16-inch box and open end openings provide versatility in tight or open access situations. It is appropriate for use on all common 6-point hex fasteners and on 12-point fasteners meeting AS 870 specifications, making it a practical choice for both precision torque applications and everyday service work.

Key Features

• SUPERTORQUE box end contacts flat surfaces behind hex points, not corners, to reduce fastener deformation under high torque
• SUPERCOMBO open end grooves direct wrench force away from fastener corners for added grip security
• Box and open end openings are identical at 5/16 inch for consistent sizing across both ends
• Meets ANSI B107.6 and SAE AS 954 aerospace specification for 12-point fasteners

• High-polish chrome finish for corrosion resistance and durability

Compatibility
