Ko-ken 4214M 1/2 Sq. Dr. Stud puller set 6mm-14mm 5 pieces

The Ko-ken 4214M is a 1/2 inch square drive stud puller set designed for removing and installing threaded studs in sizes ranging from 6 mm to 14 mm, making it suitable for automotive, mechanical, and maintenance applications. The set includes five pullers covering commonly used sizes—6, 8, 10, 12, and 14 mm—allowing flexibility across different fastening requirements. Each tool is designed with an internal gripping mechanism that tightens around the stud as torque is applied, enabling controlled removal without causing significant damage to the threads, which is useful when the stud needs to be reused. The body features a hexagonal design that helps distribute load during operation and reduces stress on internal components such as rollers and cages, supporting smoother engagement during use. With a 1/2 inch square drive, the set is compatible with commonly used ratchets, breaker bars, and extensions, allowing easy integration into standard toolkits. The tools can be used in confined or recessed areas where direct gripping methods may not be effective. The set is typically supplied in a metal case that helps keep the components organized and protected during storage or transport. It can be used for repair, disassembly, and maintenance work where stud bolts need to be removed efficiently while maintaining thread condition.
