3 Pcs 40CR Sliding Wrench Breaker Bar 1/2" Drive 10" Long, Grey

This drive sliding wrench is forged from 40CR alloy steel, offering high tensile strength, high hardness, excellent toughness, superior wear resistance and deformation resistance. Heat treatment can increase hardness and strength, thereby improving durability and wear resistance, and enabling high-torque applications;Phosphating surface treatment can provide rust prevention and oil retention properties to enhance lubrication retention and wear resistance. Spring-loaded detent ball securely holds the socket in place, preventing it from falling. Sliding the straight bar to one side of the T-bar increases leverage, thereby applying greater torque to the fastener. The movable square drive head in the wrench can be used with sockets of various sizes. The T-shaped handle is ergonomically designed for easy operation and a comfortable grip. The extension breaker bar socket hand tool is suitable for automotive repair, machinery maintenance, DIY crafts, home maintenance, and industrial assembly.
