Williams 1501MRMHW Preset Hex Drive Torque Wrench

Product Description

The WILLIAMS 1501MRMHW is a preset-style torque wrench with a 1/4 inch hex drive, designed for fastening applications that require consistent, repeatable torque output. It delivers a torque range of 20 to 150 in/lb (2.8 to 15.3 Nm), making it well-suited for light- to medium-duty assembly and service work. The preset mechanism eliminates the need for the technician to set torque manually on each use, reducing the risk of over- or under-torquing fasteners. At 10.15 inches overall length and 1.46 pounds, it is compact enough for use in tight spaces common in HVAC, plumbing, and electrical service environments. Licensed technicians and experienced tradespeople are the primary users of this tool.

This torque wrench is appropriate for residential and light commercial service applications where 1/4 inch hex fasteners must be driven to a defined torque specification. Common use cases include equipment assembly, panel fastening, and component replacement tasks encountered by HVAC technicians, plumbers, and electricians. The preset design is especially practical in high-volume service environments where the same torque value is applied repeatedly across multiple fasteners or units.

Key Features

• Preset torque design delivers consistent output without manual adjustment between uses
• Torque range of 20 to 150 in/lb (2.8 to 15.3 Nm) covers a broad range of light- to medium-duty fastening tasks
• 1/4 inch hex drive compatible with standard hex-drive sockets and bits
• 10.15 inch overall length suits use in confined spaces
• Meets or exceeds ASME and ISO 6789 torque tool standards

Compatibility

Designed for use with standard 1/4 inch hex drive accessories and compatible with fastening applications requiring a torque output within the 20 to 150 in/lb range.

Installation Notes

This tool is intended for use by qualified tradespeople familiar with torque specifications for the fasteners being driven. Always verify that the fastener torque requirement falls within the 20 to 150 in/lb operating range before use. Do not apply force beyond the preset value, and do not use the tool as a breaker bar or for loosening fasteners. Store the wrench at its lowest torque setting when not in use to preserve the internal spring calibration.
