Ko-ken 6100M-18 3/4 Sq. Dr. Stud Puller 18mm 36mm Hex Length 100mm
A stud puller is a specialized tool used for removing or installing threaded studs from engine blocks, machinery, or other mechanical components. It works by gripping the stud securely, allowing for the application of torque to either extract the stud from its seated position or install it without damaging the threads. The tool typically has a cam or collet mechanism that tightens around the stud as torque is applied, ensuring a firm grip.
