Socket Extension 1/4" 50 mm Proxxon PR23707

The Proxxon Socket Extension 1/4" 50 mm (PR23707) is a compact extension bar designed to increase the reach of 1/4" drive sockets. Made for use with hand ratchets, torque wrenches and other compatible 1/4" drive tools, this 50 mm extension helps access recessed or hard-to-reach fasteners in automotive, machinery maintenance and assembly work. The design emphasizes a precise fit between drive and socket to ensure reliable torque transfer and reduced play.

Advantages

The extension provides a practical increase in reach without significantly increasing leverage or changing the handling characteristics of the ratchet. Its 1/4" drive interface ensures compatibility with a wide range of sockets and tools commonly used in precision and light-duty applications. The 50 mm length is a balance between access and control, allowing work in tighter spaces while maintaining a secure connection and consistent torque transmission.

Suitable for

• Accessing recessed bolts and nuts in automotive engines and assemblies
• Maintenance and repair of small machinery and equipment
• Assembly tasks requiring precise fit and limited clearance
• Use with hand ratchets, torque wrenches and other 1/4" drive tools

Key specifications

• Drive size: 1/4" (6.35 mm)
• Length: 50 mm
• Material: tool steel (chrome-finish or corrosion-resistant coating typical for hand tools)
• Connection type: square drive to accept 1/4" sockets and tools
• Intended use: hand-operated torque and ratchet applications

How to use

Select a matching 1/4" socket and attach it to the extension by pushing the socket onto the square drive until it seats. Attach the extension to a compatible 1/4" hand ratchet, torque wrench or driver. Use steady, controlled force appropriate for the fastener and tool; avoid impact or excessive torque beyond the tool's rated capacity. When finished, detach the socket and store the extension with other hand tools to prevent loss or damage.

Usage recommendations

Use the extension primarily for hand-operated tasks and avoid applying power-tool impact loads. For torque-critical applications, verify the torque settings using a calibrated torque wrench and consider the effect of extension length on torque readings. Keep the extension clean and lightly lubricated at the square joint to maintain secure engagement and prevent corrosion.
