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

The Lisle 28100 1/2" Drive Torque Angle Meter is an essential professional-grade instrument for precise fastener tightening in demanding automotive and industrial applications. This specialized Lisle torque angle gauge ensures accurate torque-plus-angle tightening, crucial for meeting OEM specifications on modern engines and components and preventing premature 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: Engineered for quick setup with standard 1/2" drive ratchets, torque wrenches, and breaker bars, integrating smoothly into existing toolsets.
• 0–360° Clear Angle Scale: Features a large, easy-to-read dial, enabling precise angle turns required for critical fasteners such as cylinder head, main cap, and connecting rod bolts.
• Locking Holding Arm: An adjustable arm braces securely against the engine or chassis, preventing unintended gauge rotation and ensuring stable, repeatable readings.
• Professional Durability: Constructed to withstand daily use in professional settings, offering resistance to common shop fluids, solvents, and impacts.

Applications

The Lisle 28100 is valuable 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 tool 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. This tool is also identified as the 28100/12 in various catalogs, providing the correct solution for demanding fastening requirements.
