Williams 2502MRMHW Preset Torque Wrench 3/8 in Hex Drive

Product Description

The WILLIAMS 2502MRMHW is a preset torque wrench with a 3/8 inch hex drive, designed for precision fastening applications where repeatable torque output is critical. Preset wrenches deliver a fixed torque value without user adjustment, reducing the risk of over- or under-torquing fasteners in controlled assembly and service work. This model covers a torque range of 30.0 to 250.0 inch-pounds (4.0 to 27.7 Nm), making it well suited for light to medium fastening tasks. The overall length measures 11.25 inches and the unit weighs 1.4 pounds. It meets or exceeds ASME and ISO 6789 standards for torque tool performance and calibration.

This torque wrench is used in mechanical service environments where consistent fastener torque is required across multiple identical fastening points. Typical applications include HVAC equipment assembly, refrigeration component service, electrical enclosure hardware, and plumbing fixture installations where manufacturer-specified torque values must be maintained. The hex drive configuration suits arbor-mounted or direct-drive fastener work, with an arbor diameter of 0.425 inches. Licensed HVAC technicians, plumbers, and mechanical contractors working on torque-sensitive assemblies will find this tool appropriate for both field service and shop use.

Key Features

• Preset torque configuration eliminates user adjustment and reduces operator error
• Torque range of 30.0 to 250.0 inch-pounds (4.0 to 27.7 Nm) for light to medium fastening
• 3/8 inch hex drive with 0.425 inch arbor diameter
• Meets or exceeds ASME torque tool standards and ISO 6789 calibration standards
• Compact 11.25 inch overall length at 1.4 pounds for easy handling in tight service spaces

Compatibility

Designed for use with 3/8 inch hex drive fastener applications requiring a preset torque output within the 30.0 to 250.0 inch-pound range.

Installation Notes

This tool is operated by qualified mechanical trades including HVAC technicians, plumbers, and industrial mechanics. Before use, confirm the preset torque value is appropriate for the fastener specification in the equipment service manual. Do not attempt to adjust or override the preset mechanism, as this will compromise calibration. Periodic recalibration per ISO 6789 procedures is recommended to maintain accuracy over the tool service life.
