Williams 2503MFRMHW Micrometer Torque Wrench 1/2 in Hex

Product Description

The WILLIAMS 2503MFRMHW is a micrometer-style torque wrench built around a 1/2 inch hex drive with a torque range of 30 to 250 ft/lb (47 to 322 Nm). The micrometer mechanism allows repeatable, click-style torque setting without the need for a separate gauge or visual confirmation mid-fastening. At 24.4 inches overall length and 4.7 pounds, it is sized for production and service work where consistent fastener torque is critical. The tool meets or exceeds ASME and ISO 6789 standards, making it acceptable for documented service procedures where calibration traceability is required.

This torque wrench is well suited for mechanical and HVAC service applications involving larger fastener assemblies — compressor mounting bolts, flange hardware, equipment bases, and structural bracketing. The 30 to 250 ft/lb range covers the mid-to-heavy torque work encountered in commercial and residential mechanical installations. It is appropriate for use by HVAC technicians, plumbers, pipefitters, and general mechanical tradespeople who need documented torque compliance on critical joints.

Key Features

• Micrometer-style adjustment for repeatable torque settings without visual estimation
• Torque range: 30 to 250 ft/lb (47 to 322 Nm) covers mid-to-heavy fastening work
• 1/2 inch hex drive accepts standard 1/2 inch drive sockets and adapters
• Meets or exceeds ASME standards and ISO 6789 calibration standards
• 24.4 inch overall length provides leverage for higher-torque fasteners

Compatibility

Designed as a general-purpose 1/2 inch hex drive micrometer torque wrench compatible with standard 1/2 inch drive sockets and accessories across mechanical trade applications.

Installation Notes

This tool is used by licensed HVAC technicians, plumbers, pipefitters, and mechanical contractors. Store the wrench at or near its minimum torque setting after use to preserve the internal spring mechanism. Verify calibration periodically per applicable service documentation or job-site quality requirements. Do not use the wrench as a breaker bar or apply torque beyond the maximum rated value.
