Key Features

• Counter-Weighted Design: Internally counter-weighted to balance torque forces, minimize off-axis load, and enhance stability, ensuring more direct energy transfer to the fastener and reducing side thrust during loosening.
• Precision 21mm Hex: Accurately machined 21mm hex opening provides a secure, non-slip fit on crankshaft pulley or damper bolts, reducing the risk of rounding.
• 1/2-inch Drive Compatibility: Designed for seamless integration with professional 1/2-inch square drive tools, including impact wrenches and torque wrenches, for versatile and reliable use.
• Professional-Grade Durability: Constructed from hardened steel with a protective black coating, offering robust performance and extended tool life in challenging workshop environments.
• Optimized Length (89mm OAL): With an 89mm overall length, this socket provides essential reach into confined engine compartments while maintaining the structural integrity required for high-torque applications.

Applications

This CRANK BOLT SOCKET is an essential tool for professional engine maintenance and repair tasks. It is primarily used for the efficient and secure installation and removal of high-torque crankshaft pulley and damper bolts. Applicable to a wide range of vehicles, it addresses 21mm hex crank pulley/damper bolts found on many GM, Ford, Chrysler, Dodge, Jeep, and Mazda engines. Its robust design makes it particularly effective for breaking loose stubborn crank bolts that are resistant to standard tools, especially when removing tightly torqued harmonic balancer or pulley bolts on engines using 21 mm crank bolt patterns. It also applies to certain Toyota and Honda vehicles.
