Proto J6232 Torque Multiplier 3200 Ft-lb 1 Inch Drive

Product Description

The PROTO J6232 is a two-stage torque wrench multiplier designed for high-torque fastening applications where standard torque wrenches cannot generate sufficient output. It accepts a 1 inch square drive and delivers a maximum output of 3,200 ft-lb through a 20:1 two-stage gear system with an effective multiplier ratio of 1:18.5. At 22.57 pounds, the J6232 is built for heavy industrial service and is typically installed by journeyman mechanics, millwrights, and industrial maintenance technicians working on large-diameter fasteners in structural, pipeline, and heavy equipment applications.

The J6232 is suited for applications requiring controlled, repeatable high-torque output without the need for hydraulic or pneumatic equipment. Common use cases include flange bolt tightening on large piping assemblies, structural bolting on industrial frames, and equipment installation where bolt torque specifications exceed the practical range of direct-drive torque wrenches. The two-stage gear system allows a technician to apply manageable input force while achieving output torque values that comply with ASME and manufacturer fastener specifications.

Key Features

• 1 inch square output drive accommodates large-format sockets and drive accessories
• 3,200 ft-lb maximum output torque for heavy industrial fastening
• 20:1 two-stage gear ratio with 1:18.5 effective multiplier ratio reduces required input effort significantly
• Two-stage gear system provides smooth, consistent torque transfer
• Compact multiplier design eliminates the need for hydraulic torque equipment in many applications

Compatibility

Designed as an OEM-style replacement or direct-use torque multiplier for industrial and mechanical applications requiring 1 inch drive tooling and output torque up to 3,200 ft-lb.

Installation Notes

Installation and use of torque multipliers should be performed by qualified mechanics or maintenance technicians familiar with high-torque fastening procedures. Before use, ensure the reaction arm is properly seated against a fixed structure to prevent rotation and tool kickback. Verify the input torque wrench calibration and confirm that the target fastener torque specification accounts for the multiplier ratio. Follow applicable ASME B18 or equipment manufacturer torque specifications when determining input wrench settings.
