Where this product is used

Ko-Ken socket adaptors and reducers convert between drive sizes, allowing sockets of one drive to be used with a ratchet, torque wrench, or impact tool of a different drive size.

• Converting between socket drive sizes to use existing sockets with different ratchet or power tool drives
• Extending the range of a socket set by adapting 3/8" sockets to a 1/2" drive ratchet or vice versa
• Workshop flexibility where multiple drive sizes are used and cross-drive socket compatibility is needed

Key specifications

Selecting the right option

Select by the female drive size (the socket side) and male drive size (the ratchet or tool side). Adaptors are used when a socket is not available in the required drive — confirm the adaptor does not reduce the torque capacity below what the application requires. Do not use standard adaptors on impact tools unless impact-rated.
