Stanley Proto torque multipliers are designed to deliver high mechanical advantages to ensure that the threaded fasteners are properly tightened. These multipliers feature a single-stage planetary gear system offering effective multiplication ratios up to 6:33:1 to transfer the largest torque in the most compact and accurate setups. They come in a maximum rated input of 200 ft lb (271 Nm) and a maximum rated output of 1200 ft lb (1626 Nm). Choose from a wide range of these Proto torque multipliers, available in standard +/- 5% of reading torque accuracy, on Raptor Supplies.
Torque wrenches require high manual force for fastening / loosening tight nuts & bolts, so they have long handles to provide the required leverage. That is the reason why torque wrenches are not suitable for tight spaces. Torque multipliers can deliver high torque with a minimum manual force and have small handles for use in confined spaces.
These tools have different gear ratios. Selected models have the gear ratio set at 1:13.6.
These torque multipliers have an accuracy rating of +/-5 percent.
