Performance Tool M205 Torque Angle Gauge, 360 Degree, 1/2 Drive

The Performance Tool M205 Torque Angle Gauge is a manual angle-measuring tool designed to work with 1/2? drive tools (like ratchets or breaker bars) to measure how far you rotate a fastener after applying torque. Rather than measuring torque in weight-units (like ft-lbs), it tells you how many degrees you’ve turned a bolt or nut during tightening — useful when specs call for an angle rather than a simple torque value.

Many modern engines and assemblies require not just a torque number, but a torque-plus-angle specification — especially for torque-to-yield (TTY) fasteners and critical engine bolts (like head bolts).

• 360 Degree angle scale in 2 degree increments
• Adjustable arm has 2 different lengths for flexibility of use
• For use with 1/2" drive tools
• Sold as each

The Performance Tool M205 Torque Angle Gauge is especially useful for:

• Automotive engine assembly & repair
• Head bolts, connecting rods, and other fasteners with torque-angle specs
• Critical industrial or mechanical assemblies
• Where precise rotation after torque matters
• DIY and professional mechanics
• Works during rebuilds, maintenance, or assembly jobs requiring consistent clamp force

Measure rotational angle accurately: The gauge has a 360° scale, marked in 2° increments, so you can follow a specified degree of rotation exactly after initial torquing.

Use with standard 1/2? drive tools: It attaches between your ratchet/breaker bar and socket, letting you read the angle as you turn — no electronics or batteries required.

Adjustable arm for fit & access: The pivoting arm adjusts to two lengths to clear engine parts or tight spaces and stay in view while tightening.
