Description
A torque wrench can drift out of tolerance with no visible sign. The Snap-on TCR175 torque comparator gives a team a quick way to catch that between lab visits. It handles loads up to 175 ft-lb, which covers most 3/8″ and many 1/2″ click wrenches.

Why check wrenches in-house
Outside calibration happens once or twice a year at most plants. Meanwhile, a dropped wrench or a heavy month on the line can shift its setting. So a short check on the TCR175 at the start of a shift or week shows problems early. As a result, the team can pull a suspect tool before it puts bad torque into a product.
Who gets the most from the Snap-on TCR175 torque comparator
- Automotive and two-wheeler lines with many small click wrenches.
- Electronics and appliance plants with a 3/8″ wrench at each station.
- Tool cribs that issue wrenches to maintenance crews.
- QA teams that audit supplier tools.
Matching it to your wrench list
A 175 ft-lb maximum suits wrenches such as the 10-75 ft-lb QD2R75A and the 20-100 ft-lb QD2100A. For heavier tools, pair it with a higher-range unit such as the TCR600, which reaches 600 ft-lb.
A simple check routine
Pick two check points for each wrench, for example 40% and 80% of full scale. Load the wrench slowly on the TCR175 until it clicks, and then read the comparator. If the result falls outside your plant’s limit, tag the wrench and send it to a lab. Otherwise, log the reading and return the tool to service.
Placement and care
Bolt the comparator to a solid bench, because a flexing mount upsets the reading. Also keep it clean and away from forklifts and carts. The TCR175 needs its own traceable check too, so book it with an accredited lab on a fixed cycle.
