Williams Comfort Products 11538 38mm Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS 11538 is a 38mm combination wrench with a 12-point box end and an open end, finished in a satin chrome surface. Combination wrenches of this type deliver versatile fastener engagement, letting technicians use the box end for torque-critical turns and the open end for fast spinning in confined spaces. The 12-point geometry increases the number of engagement positions per revolution, reducing the arc needed to reposition the wrench in tight quarters. This tool is used by HVAC technicians, plumbers, and mechanical contractors working on heavy-duty fasteners in commercial and industrial installations.

The 11538 is suited for trade professionals who regularly encounter large metric fasteners on mechanical equipment, structural hardware, and piping assemblies. At 38mm, this wrench addresses the larger fastener sizes common in commercial HVAC equipment, boilers, large-diameter flange hardware, and industrial plumbing connections. The satin finish reduces glare and resists corrosion under typical shop and field conditions.

Installation Notes

This wrench is a hand tool used by licensed HVAC technicians, plumbers, and mechanical contractors. Always confirm fastener size before applying torque to avoid rounding. Power down or isolate mechanical systems before breaking or torquing fasteners on pressurized or energized equipment. Follow applicable codes and equipment manufacturer guidelines for fastener torque requirements.
