Williams 1502MRMHW Torque Wrench 3/8 Inch Hex Drive

Product Description

The WILLIAMS 1502MRMHW is an interchangeable-head torque wrench with a 3/8 inch hex drive, built for precision fastening in trade and industrial applications. It delivers a torque range of 20 to 150 inch-pounds (2.8 to 15.3 Nm), with a scale graduation of 0.12 inch-pounds for fine adjustment. The overall length of 10.15 inches provides a practical reach for confined spaces. This wrench meets or exceeds ASME and ISO 6789 standards, making it appropriate for use in mechanical, HVAC, plumbing, and electrical service work where documented torque compliance is required.

The 1502MRMHW is suited for residential and commercial service environments where consistent torque application is critical. The interchangeable head design allows technicians to swap drive configurations without changing the torque body, reducing tool inventory. Typical applications include fastening panel hardware, equipment mounting bolts, and connection fittings where low to moderate torque values must be controlled and verified. Licensed technicians and skilled tradespeople in multiple disciplines will find this range appropriate for small-fastener work on mechanical equipment.
