CDI 1501MRPH 1/4-Inch Drive Adjustable Micrometer Torque Wrench, Torque Range 20 to 150-In.lbs

The Williams 1/4″ Drive 150 Inch-Pound Dual Scale Micro-Adjustable Torque Wrench with Comfort Grip is a precision torque wrench built for controlled tightening in low-torque applications, combining reliable performance with user comfort. It features a dual torque scale in both inch-pounds and Newton-meters, allowing you to set torque anywhere from approximately 20 to 150 in-lb (2.8 to 15.3 Nm), with easy-to-read laser-etched graduations and a positive “click” feedback when the preset torque is reached. The tool is equipped with an ergonomic comfort-grip handle that’s designed to reduce hand fatigue and improve grip compared to all-metal handles, while the internal micrometer-adjustable mechanism provides smooth, precise torque setting. A spring-loaded positive lock ring keeps the torque setting secure during use, and most versions include quick-release socket retention features for efficient socket changes. The wrench meets or exceeds industry standards such as ASME and ISO 6789 and is individually serialized with a calibration certificate traceable to NIST, making it suitable for automotive service, industrial maintenance, machinery assembly, and other tasks where accurate, repeatable torque is critical.
