1/2" Drive Torque Angle Meter for Precision Fastening - Lisle

The Lisle 28100 1/2" Drive Torque Angle Meter is a professional-grade instrument engineered for precise fastener tightening in demanding automotive and industrial applications. This specialized Lisle torque angle gauge ensures accurate torque-plus-angle tightening, a critical requirement for meeting OEM specifications on modern engines and preventing premature component failure. It integrates seamlessly with any 1/2" drive torque wrench or breaker bar, providing the exact angular measurements needed for torque-to-yield fasteners.

Key Features

• 1/2" Drive Compatibility: Designed for quick integration with standard 1/2" drive ratchets, torque wrenches, and breaker bars, fitting smoothly into existing professional toolsets.
• 0–360° Clear Angle Scale: Features a large, high-contrast dial for precise angle turns, essential for critical fasteners such as cylinder head, main cap, and connecting rod bolts.
• Locking Holding Arm: An adjustable arm securely braces against the engine block or chassis, preventing unintended gauge rotation and ensuring stable, repeatable readings during operation.
• Professional Durability: Constructed to withstand the rigors of daily professional use, offering resistance to common shop fluids, solvents, and impacts, ensuring longevity in demanding environments.

Applications

The Lisle 28100 1/2" Drive Torque Angle Meter is indispensable for professional automotive shops, fleet maintenance operations, and engine rebuild facilities. It is particularly suited for late-model engines that specify torque-plus-angle tightening, including cylinder head bolts on passenger cars and light trucks. Technicians will find this Lisle torque angle meter invaluable for connecting rod and main bearing cap bolts during engine rebuilds, as well as for suspension, subframe, and other chassis fasteners requiring an angle turn after initial torque.
