The WILLIAMS COMFORT PRODUCTS TM-393 is a torque multiplier rated to 3200 foot-pounds of output torque. Torque multipliers use a planetary gear reduction system to allow a technician to apply high torque values to fasteners without requiring a large input force. This tool is used in heavy mechanical assembly, equipment maintenance, and industrial service work where standard ratchets and breaker bars cannot generate sufficient torque. At 22.375 pounds, the TM-393 is a substantial unit built for demanding trade applications. Licensed mechanics, industrial maintenance technicians, and heavy equipment service professionals are the primary users.
The TM-393 is suited for applications requiring precise, high-torque fastener installation or removal. Typical use cases include flange bolting, large-diameter pipe fittings, equipment mounting hardware, and structural fastener service in industrial and commercial settings. The tool is sold as a single unit and is appropriate wherever controlled, high-torque output is needed without access to hydraulic or pneumatic torque equipment.
Designed for use in industrial, commercial, and heavy mechanical service applications requiring torque output up to 3200 foot-pounds. Consult the drive size and reaction arm specifications to confirm fitment with your fastener size and work envelope before installation.
Installation and operation of a torque multiplier of this capacity should be performed by qualified mechanical or industrial service technicians familiar with high-torque fastener procedures. Ensure all reaction arms are properly engaged against a fixed surface before applying input torque to prevent tool movement or fastener damage. Consult applicable equipment service manuals and any relevant industry torque specifications before use. Always wear appropriate personal protective equipment when operating high-torque hand tools.
