Williams Comfort Products JHW1220SC Combination Wrench 5/8 in

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1220SC is a 5/8 inch combination wrench built for trade professionals who need reliable torque performance on hex fasteners. The box end uses a SUPERTORQUE design that applies wrenching force to the flat surfaces behind fastener points rather than the corners, reducing the risk of rounding or deforming the fastener. The open end features a SUPERCOMBO design with grooves that redirect force away from fastener corners as well. Both openings share the same 5/8 inch size. Overall length is 9.5 inches. A high-polish chrome finish resists corrosion and simplifies cleanup in the field.

The JHW1220SC suits residential and commercial maintenance, mechanical contracting, HVAC service, plumbing, and general trade applications where fastener integrity matters. The identical box and open end sizing gives techs a single tool for two wrenching methods without switching. The SUPERTORQUE box end meets or exceeds aerospace specification AS 954 for 12-point fasteners as defined by AS 870, making it appropriate for precision torque applications and general hex fastener work alike. The wrench is sold individually.
