Socket adapter Proxxon 3/8" to 1/4" (PR23564)

The Proxxon socket adapter 3/8" to 1/4" (PR23564) is a compact adapter designed to allow 1/4-inch sockets and accessories to be driven by 3/8-inch drive tools. Constructed to transfer torque reliably between different drive sizes, this adapter provides a straightforward solution when a larger ratchet or drive tool must be used with smaller sockets. It is intended for workshop environments, automotive repair, and general maintenance where cross-size compatibility is required.

Advantages

The adapter is compact and easy to fit, enabling quick conversion between drive sizes without additional tools. Machined engagement surfaces provide secure seating and efficient torque transfer while minimizing play. Its durable construction resists wear from repeated use and maintains fit accuracy over time. The slim profile helps access confined spaces where larger adapters might obstruct operation.

Suitable for

• Using 1/4" sockets with 3/8" ratchets or drive tools
• Automotive repair tasks requiring small sockets and higher-torque tools
• General workshop maintenance and equipment assembly
• Situations where a compact adapter is needed for tight spaces

Key specifications

• Input drive: 3/8 inch square drive
• Output drive: 1/4 inch square drive
• Material: hardened steel construction for durability
• Finish: corrosion-resistant surface treatment
• Form factor: compact, low-profile adapter design

How to use

Fit the 3/8" square end of the adapter into the 3/8" drive tool or ratchet until it clicks or seats firmly. Attach the required 1/4" socket or accessory onto the 1/4" square end until it is fully seated. Apply torque within the normal operating range of the socket and drive tool. Remove by pulling the socket off the adapter and disengaging the adapter from the drive tool. Inspect seating and condition before use to ensure safe operation.

Usage recommendations

Use the adapter only within the torque limits of the smaller socket and the drive tool, avoid excessive impact loading, and keep contact surfaces clean to preserve fit and prevent wear. Store in a dry place and inspect regularly for signs of rounding or damage before critical tasks.
