OTC 4554 Stinger 1/2" Drive Torque Angle Gauge - OTC Tools and Equipment

The OTC 4554 Stinger Torque Angle Gauge is an essential tool for professional technicians and mechanics working with modern automotive engines. Designed for precision, this 1/2" drive gauge accurately measures the angle of rotation after pre-torque, a critical step for fasteners that require specific torque-angle tightening sequences, commonly known as torque-to-yield (TTY) fasteners. Its robust construction ensures reliable performance in demanding shop environments.

Key Features

• Accurate Angle Measurement: Features a clear 360° scale, precisely marked in 2° increments, with intervals at 10° and 30° for enhanced readability.
• Easy Reset Mechanism: The tool housing can be easily turned to zero the gauge, allowing for quick setup between applications.
• Universal Compatibility: Equipped with standard 1/2" male and female square drives, making it compatible with most common ratchets, breakers bars, and torque wrenches.
• Professional Grade: Built by OTC Tools and Equipment, ensuring the durability and precision required for professional automotive and industrial service.

Applications

This OTC 4554 Stinger Torque Angle Gauge is indispensable when servicing many late-model engines that utilize torque-to-yield (TTY) fasteners. These fasteners are designed to stretch permanently once a specific torque and angle are applied, making a torque angle gauge critical for achieving correct clamping force and preventing engine damage or component failure. Common applications include cylinder head bolts, connecting rod bolts, and main bearing cap bolts on a wide range of vehicles where manufacturers specify angle-tightening procedures.
