The breaker bar is equipped with a spring-loaded ball that locks securely into the socket and allows for quick removal. 【High Quality & Durability】The torque wrench handle is made of aluminum alloy, treated with black phosphating, provides a comfortable grip and is non-slip, and the head is made of Cr-Mo steel for higher strength. The main body of the 1/2” breaker bar is made of Cr-V steel, rust-resistant, making it highly durable, and its head is made of Cr-Mo steel, which can withstand greater torque. 【Easy Operation】Simply pull down the lock knob and hold it until the torque setting is complete. Release your hand, and the lock knob will automatically rebound to lock in the value. The laser-printed N·m scale on the handle ensures that the range scale is clear and easy to identify. 【Versatile Use】The set includes a ratchet torque wench and a breaker bar for demolition (lever force).
