Williams 1002MFRMHW Micrometer Torque Wrench 3/8 in Hex Drive

Product Description

The WILLIAMS 1002MFRMHW is a micrometer-style torque wrench with a 3/8 inch hex drive, designed for precise fastener torque application in mechanical, HVAC, plumbing, and general trade service work. It delivers a torque range of 10 to 100 ft/lb (16.9 to 132.2 Nm), making it suitable for a wide range of assembly and service tasks. The wrench measures 16 inches in overall length and meets or exceeds ASME and ISO 6789 standards for torque tool accuracy. Licensed technicians and journeyman-level tradespeople rely on tools at this specification level for repeatable, code-compliant fastening on equipment installations and service calls.

This torque wrench is used across residential and commercial trade applications wherever controlled fastener torque is required. Common scenarios include equipment mounting, flange bolting, pipe fitting assembly, and electrical enclosure work. The 3/8 inch hex drive accepts standard 3/8 inch drive sockets, making it compatible with commonly available socket sets in trade tool kits. The 10 to 100 ft/lb range covers the majority of fastener sizes encountered in HVAC equipment installation, plumbing fixture work, and light structural assembly.

Installation Notes

This tool is used by licensed HVAC technicians, plumbers, electricians, and mechanical contractors for equipment installation and service work. Always set the torque value before applying the wrench and release the adjustment to minimum torque after use to preserve the internal spring calibration. Follow the fastener manufacturer torque specifications and applicable code requirements for the work being performed. Periodic recalibration per ISO 6789 intervals is recommended to maintain accuracy.
