Its short 42 mm length allows better reach into tight engine bays or machinery housings without excessive leverage. Manufactured by a professional tools brand, it is made to withstand regular workshop use and fits common 3/8" sockets and ratchets for straightforward compatibility.

Suitable for

• Automotive repair and maintenance in confined engine or chassis areas
• General mechanical assembly and disassembly tasks
• Maintenance of household appliances and small machinery

Key specifications

• Drive size: 3/8"
• Overall length: 42 mm
• Quantity: 1 piece
• Function: adapter/short extension for sockets

How to use

Select a compatible 3/8" socket and press it onto the square drive of the adapter until it locks. Insert the adapter's square end into the ratchet, extension bar, or handle and ensure the detent ball or locking feature engages if present. Use the assembled tool to apply torque as required, taking care not to exceed the recommended torque ratings for the socket and fastener type. Remove the adapter by pulling the socket off and disengaging it from the drive tool when the job is complete.

Usage recommendations

Use the adapter as part of a matched 3/8" tool set and avoid impact or pneumatic tools unless the adapter is specified for such use. Keep the adapter clean and apply light lubrication to moving detent parts if resistance appears. Inspect regularly for wear or deformation and replace if any damage is found.
