X-4 TOOL Perf-A-Torq™ PRECISION TORQUE LIMITERS

X-4 Tool Perf-A-Torq precision torque limiters convert any standard ratchet or socket drive tool to a torque limiting wrench.

Perf-A-Torq™ precision torque limiters can be attached to any standard drive tool to provide the ultimate in torque control. Once the torque limit is set, The X-4 Tool Perf-A-Torq Torque Limiter prevents the applied force from exceeding the setting. When the preset torque value is reached the torque limiter releases with an audible ‘click’. Perf-A-Torq torque limiters may also be used in automated applications at speeds lower than 300RPM. Please note that Perf-A-Torq limiters are NOT recommended for use with impact type driving tools.

X-4 Tool Perf-A-Torq Torque Limiters are available in four standard sizes for use with 3/8" and 1/2" standard square drive tools, Perf-A-Torq limiters combine compactness and a unique resettable torque limit design to maintain precise torque control and accurate repeatability in any application where precision control is a necessity.
