Precision torque for small fasteners

This CDI micrometer torque wrench covers a 20 to 150 in-lb range with a 1/4 inch drive. It suits technicians who tighten small bolts on engines, electronics or aerospace assemblies where precise inch-pound values are specified. The dual-scale micrometer sleeve shows both inch-pound and Newton-metre readings for quick reference.

Simple setup with audible feedback

Pull the locking ring, turn the handle until the desired value aligns with the index line, then release the ring to lock the setting. The ratchet head clicks audibly when the preset torque is reached in either clockwise or counter-clockwise direction. Over-tightening past the click or using the wrench as a breaker bar are the most common errors that damage the internal mechanism.

Consistent repeatability during extended use

The micrometer design maintains its calibrated accuracy across many consecutive fastenings without the drift seen in beam-type tools. A tether hole in the handle allows a safety lanyard for elevated work. The wrench is not suited for high-torque applications beyond 150 in-lb or for impact-driven sockets.

Questions about this item

How do I verify the 1501MRPH is clicking at the correct 150 in-lb setting after setup?

Set the micrometer sleeve to 150 in-lb, attach a calibrated torque tester, and apply force clockwise until the wrench clicks; the tester should read within the tool's stated accuracy tolerance.

What comes in the box with the 1501MRPH and what must I purchase separately?

The wrench itself is supplied; sockets, extensions, and a calibration certificate are not included and must be bought separately.

Which torque range version should I choose for jobs needing 20 to 150 in-lb?

The 1501MRPH covers exactly 20 to 150 in-lb with 1 in-lb increments, so select this model when your specifications fall inside that window.
