Williams JHW1230MSC Combination Wrench 30 Mm 12-point

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1230MSC is a 30 MM combination wrench built for professional tradespeople who need reliable torque performance on hex fasteners. The 12-point box end uses a SUPERTORQUE design that contacts the flat surfaces of the fastener rather than the corners, reducing the risk of rounding or deforming fastener points under high-torque conditions. The open end incorporates SUPERCOMBO grooves that redirect wrenching force away from fastener corners as well. A high-polish chrome finish rounds out the construction. This wrench weighs 2.297 pounds and measures 16.7 inches in length.

This combination wrench is suited for HVAC, plumbing, electrical, and general mechanical service work where 30 MM hex fasteners are common. The 12-point box end provides twice the ratcheting positions of a standard 6-point box end, making it useful in confined spaces where swing arc is limited. The open end handles quick fastener engagement when access allows. It is sold individually and is appropriate for both residential and commercial service applications.
