Choose the Correct Fit
Match the 1/2 in input to your hand-tool drive and the 3/8 in output to the socket. Confirm both directions before ordering.
A drive adapter changes the connection size; it does not establish a higher torque rating for the connected tools. Work within their limits.
Installation & Care
Fully seat the adapter and socket before applying force. Keep the assembly straight and check that the socket remains securely retained.
Clean the drive faces and inspect for rounding, cracking or plating damage. Do not use this hand-tool adapter in impact service without an explicit rating.
