OTC 4554 1/2-Drive Torque Angle Gauge
OTC 4554 is a torque-angle gauge with 1/2-inch male and female square drives. Its 360-degree scale is marked in 2-degree increments, with additional 10- and 30-degree intervals described. It measures fastener rotation for a specified torque-plus-angle procedure; the dial is an angular scale rather than a torque scale.

Product questions and answers
Does it display ft-lb or Nm torque?
No. The specified dial measures rotation angle, not tightening torque.
Does a 2-degree graduation guarantee ±2-degree accuracy?
No. Graduation spacing and accuracy are different specifications; no tolerance is supplied.
Does torque-angle use automatically allow reusing a bolt?
No. Follow the assembly manufacturer's fastener replacement requirements.
