The Neilsen Torque Setting Angular Gauge is an essential precision tool for automotive mechanics and DIY enthusiasts who perform critical engine work, such as cylinder head installation or rod bolt tightening. This gauge allows users to achieve exact torque-to-yield specifications by measuring rotation in degrees rather than just torque force, ensuring bolts are stretched within manufacturers' tolerances. While it provides high-level accuracy for mechanical assemblies, users must be aware that it requires a stable mounting point and careful alignment to ensure consistent readings.

No, this specific model is designed for 1/2 inch drive tools. You would need a 1/2 to 3/8 inch adapter to use it with smaller wrenches.
Angular gauges are specifically intended for torque-to-yield engine bolts. Standard wheel lug nuts are typically tightened by torque alone, not by angle.
The gauge is calibrated at the factory. Ensure the housing remains free of grit to maintain smooth rotation and accuracy.
The arm is designed for physical bracing against an engine surface; it does not rely on magnetic attachment.
Simply reset the gauge to zero once a full rotation is reached and continue until the total required angle is satisfied.
Ensure the tension arm is securely braced against a static engine component to prevent movement during the tightening sequence.
Clean the lens surface with a degreaser and use a high-lumen work light to ensure the 2-degree increments are clearly visible.
To set up the gauge, attach the female end to your 1/2 inch drive torque wrench and the male end to the socket. Place the unit onto the bolt head and rotate the outer housing of the gauge until the needle rests at zero. Ensure the reference rod is braced against a solid, non-moving part of the engine to prevent it from slipping during rotation. After use, wipe the tool clean with a dry cloth to remove any oil or grease, and store it in a cool, dry place away from magnetic fields to keep the internal calibration accurate.
