Angle rotation gauge HOGERT HT8G421, 360° range, 1/2" square drive

HOGERT HT8G421 is an angle rotation gauge for measuring and setting rotational angles across a full 360° range. The tool features a 1/2" square drive for direct connection to compatible ratchets, torque wrenches or extension adapters. It is designed for mechanical assembly, maintenance and calibration tasks where accurate angular positioning and repeatable angle measurements are required. Constructed from chrome-vanadium alloy steel, the gauge is intended for workshop and industrial use where a simple, mechanical solution for angle-based tightening is needed.

Advantages

The HOGERT HT8G421 provides a continuous 360° measurement scale and a direct 1/2" drive connection, enabling quick integration with common torque tools and socket sets. Its chrome-vanadium construction offers wear resistance and durability for repeated use. With a specified accuracy of 2° the gauge supports reliable, repeatable angle-based tightening procedures without electronics or batteries.

Suitable for

• Final tightening of bolts and nuts using measured rotation angle
• Cases where tightening must be controlled by angle after applying a torque
• Automotive assembly and maintenance tasks
• Industrial machinery adjustment and calibration
• Workshop and field service operations requiring portable angle measurement

Key specifications

• Measurement range: 360°
• Drive size: 1/2" square drive (compatible with 1/2" sockets and ratchets)
• Material: chrome-vanadium alloy steel (CrV)
• Accuracy: ±2°
• Construction: mechanical, non-electronic gauge
• Quantity in set: 2 pieces

How to use

Attach the HT8G421 to a compatible 1/2" ratchet or torque wrench and set the reference zero position on the dial or index point. Apply the specified preload torque if required, then rotate the fastener by the required number of degrees indicated on the gauge. Observe the dial while turning to reach the target angle. For repeatable results, maintain a steady turning speed and ensure the drive connection remains fully engaged during rotation.

Usage recommendations

Use the gauge in combination with a correctly calibrated torque wrench when procedures require both torque and angle control. Periodically inspect the drive connection and dial for wear, and avoid side loads or impacts that could affect accuracy. Store the tool in a dry environment to prevent corrosion.
