Adapter socket drive Proxxon 1/4" (6.35 mm) female to 3/8" (9.5 mm) male PR23782

Proxxon PR23782 is a compact metal drive adapter that converts a 1/4" (6.35 mm) female square socket into a 3/8" (9.5 mm) male square drive. Designed to provide cross-compatibility between socket sizes, this adapter allows users to operate 3/8" sockets and accessories with hand tools, ratchets or drivers that have a 1/4" drive. Its solid construction suits repeated use in mechanical, automotive and general maintenance tasks where space is limited or when carrying a single driver is preferred.

Advantages

The adapter offers a straightforward solution for matching different socket drive sizes without the need to change tools. Made from durable metal, it provides a reliable connection between 1/4" drive tools and 3/8" sockets while keeping overall size compact for accessibility in tight spaces. Its simple design minimizes play between drive and socket, supporting efficient torque transfer for common fastening tasks.

Suitable for

• Automotive repair and light vehicle maintenance
• Mechanical assembly and disassembly tasks
• General workshop and household maintenance
• Field service work where tool versatility and compactness are needed

Key specifications

• Input drive: 1/4" (6.35 mm) female square
• Output drive: 3/8" (9.5 mm) male square
• Material: metal construction for durability
• Compact form factor for access in confined spaces
• Intended use: manual hand tools and ratchets

How to use

Insert the 1/4" male end of your ratchet or driver into the adapter's 1/4" female opening until it seats securely. Attach the 3/8" socket or accessory onto the adapter's 3/8" male square drive and ensure it engages properly before applying torque. Use the adapter for manual turning applications; avoid applying impact tool forces unless the adapter's suitability for impact use is explicitly indicated by the tool manufacturer.

Usage recommendations

Check compatibility of sockets and tools before use and inspect the adapter for wear or damage periodically. Use appropriate torque for the socket size and application to prevent slipping or rounding of fasteners. Store the adapter in a dry environment to reduce corrosion risk.
