1/4" Hex Dr. Adaptor 1/4 Square Pin type

Featuring a traditional pin retention system, this adaptor provides reliable socket engagement through a hardened steel retaining pin that locks sockets securely in place. The pin mechanism offers positive retention with a satisfying click, ensuring your sockets stay firmly attached during operation while allowing quick, deliberate socket changes when needed. Ideal for controlled work environments where precision matters most. The 1/4" hexagonal input shank is machined to exacting specifications, ensuring zero-wobble engagement with impact drivers, power drills, and quick-change chuck systems. Ko-ken's proprietary surface finish enhances retention force and maximizes torque transmission efficiency, reducing wear on both the adaptor and your power tools.
