Williams Comfort Products JHW8720 Box End Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW8720 is a 12-point offset box end wrench with a 1/4 x 5/16 inch opening, built for professional tradespeople who need reliable torque in confined spaces. The SUPERTORQUE box opening design applies wrenching force to the flat surfaces behind the fastener points rather than the corners, allowing higher torque without rounding or deforming hex fasteners. The 60-degree offset box end provides added knuckle clearance and bolt clearance in tight working areas. Size markings are stamped clearly on the handle ends for fast identification on the job.

This wrench is suited for HVAC, plumbing, electrical, and general mechanical service work where fasteners are seated in restricted or awkward locations. The offset design makes it practical for use in equipment panels, behind pipe runs, and inside cabinet enclosures where a straight wrench cannot get adequate swing. It is sold individually and is appropriate for both service technicians and installation crews who work with 1/4 inch and 5/16 inch hex fasteners regularly.
