The Yato Adaptor converts a 3/4‑inch female drive to a 1/2‑inch male drive, allowing the use of 1/2″ sockets or tools with a larger 3/4″ drive handle or wrench. Made from hardened chrome‑molybdenum (CrMo / CrV) steel with a corrosion‑resistant finish, it’s built to withstand high torque and tough workshop conditions. Its precise square‑drive machining and spring‑loaded detent ensure secure socket retention and reliable torque transfer, helping prevent slippage or accidental socket release under load. This adaptor is especially useful when you want to use a single ratchet, breaker bar, or torque wrench with sockets of different drive sizes — reducing the need to carry multiple tools in different drive sizes. It’s a compact, durable, and convenient accessory for workshops, automotive repair, and general mechanical tasks where flexibility and socket‑drive compatibility matter.
