Socket 3/8" Proxxon PR23538 6-point, 11 mm long

Proxxon PR23538 is a 6-point, 11 mm socket with a 3/8" drive in a long configuration. Engineered for manual and ratchet operation, this socket offers a precise fit on hex fasteners and improved torque transfer through its 6-point design. The extended length facilitates access to recessed or hard-to-reach bolts and nuts, making it appropriate for workshop and automotive applications where greater reach is required.

Advantages

The 6-point geometry reduces rounding of fastener corners and concentrates contact on flats for secure engagement. A long body increases reach while maintaining strength for typical hand-tool torque levels. The 3/8" drive is compatible with a wide range of ratchets, extensions and adapters used in mechanical and maintenance work. Durable construction and precise internal tolerances provide consistent performance and repeatable fit on 11 mm hex fasteners.

Suitable for

• Accessing recessed bolts and nuts in engines and machinery
• General mechanical and maintenance work
• Automotive repairs and component assembly
• Workshop tasks requiring a longer socket reach

Key specifications

• Drive size: 3/8"
• Socket type: 6-point (hex)
• Nominal size: 11 mm
• Configuration: long socket for extended reach
• Intended use: hand and ratchet operation

How to use

Select a compatible 3/8" ratchet or extension and attach the socket securely to the drive. Position the 11 mm socket squarely on the hex fastener to ensure full contact across the flats, then apply steady, controlled torque. For tight spaces, use the long profile to reach recessed fasteners; if additional leverage is required, add an appropriate extension or use a breaker bar rated for the drive size. Avoid using impact tools unless the socket is specifically rated for impact use.

Usage recommendations

Inspect the socket and fastener for damage before use and keep mating surfaces clean to preserve fit accuracy. Use the socket with tools matched to the 3/8" drive and observe manufacturer torque limits for the fastener material. Store sockets in a protective tray or rail to prevent corrosion and to maintain internal tolerances.
