Tightening threaded joints to a set value is what Crossmaster torque wrenches are made for. They give maintenance and assembly teams a repeatable pull, so joints are neither left loose nor overtightened to the point of damaging threads, fasteners or the parts around them. Workshops and plants in automotive, metalworking, agriculture, energy and general industrial assembly rely on this kind of tool for both production work and quality checks.
The range covers ratchet heads with 24 or 72 teeth and a torque angle gauge, listed as a protractor. A 72-tooth head needs a smaller swing to engage the next tooth, which helps where access is restricted. The 24-tooth version is the choice when high torque is the priority. Codes 9936105, 9936107, 9936112, 9936113, 9936120, 9936121 and 9936126 cover different capacities and drives: 1/4, 3/8, 1/2 and 3/4. Code 9980502 is the angle gauge, with a 1/2 drive. Every code stands for one drive and range combination.
Typical jobs include machinery, engines, transmissions, structures and process equipment. In automotive and heavy vehicle shops, that means cylinder heads, wheels, injectors and suspension parts. Plant maintenance uses them on flanges, pumps, compressors and assembly lines. In agriculture, they come out for seeders, harvesters and tractors, where a joint tightened to the wrong value tends to fail early.
Selection starts with the torque you need: the setting should sit on the scale, ideally around the middle third. The drive has to match the socket or accessory in use, and the tooth count follows the space you have and the torque involved. The angle gauge is for joints specified as torque plus angle. On the job, keep calibration checks on schedule, use the tool for tightening only and never for loosening, and return it to its case with the spring released.
If you are matching a tool from another line, compare torque range, drive type and accuracy. Designations differ between makers, but a 1/2" wrench of similar range can stand in for another as long as the specifications line up. Send the code you have, even from another brand, or an unidentified part, and we will point you to the compatible option. MR Industrial Accessories LLC supplies the Crossmaster line and helps you settle on the right model for the application.

Frequently asked questions
- What changes between a 24-tooth and a 72-tooth torque wrench?
- The tooth count sets the smallest swing of the ratchet head. A 72-tooth head engages sooner, so it works better where there is little room to move the handle. A 24-tooth head is built for high torque. Which one fits depends on the job and the space around the fastener.
- How do I pick the torque range?
- Match the wrench to the value you will apply, and aim to work around the middle third of the scale. Too low a setting on a large wrench costs accuracy; too high a setting puts strain on the tool. Tell us the value and we will suggest the model.
- When is a torque angle gauge used?
- It is a degree protractor that mounts on the wrench for joints specified as torque plus angle, such as cylinder heads and other critical connections. You apply the initial torque first, then turn the fastener a set number of degrees. Code 9980502 has a 1/2 drive.
