1/2" Sq. Dr. Extension Bar Pin type
Ko-ken extension bars represent precision engineering excellence designed to deliver extended reach capability and dependable performance across demanding professional fastening applications. This 1/2 inch square drive pin type extension bar features a substantial 300mm length, providing essential access to deeply recessed fasteners in engine compartments, transmission housings, differential assemblies, and machinery enclosures where direct ratchet engagement cannot be achieved. The traditional pin retention system provides reliable socket engagement through a hardened steel retaining pin that locks sockets securely in place, ensuring your sockets remain firmly attached during operation while allowing quick, deliberate socket changes when required. This proven retention mechanism delivers positive locking with an audible click, ideal for controlled professional environments where secure socket attachment and consistent tool performance are essential.
