Socket 18 mm 12-point 1/2" Proxxon PR23311

Proxxon 18 mm 12-point socket with 1/2" drive (model PR23311) is a compact hand tool accessory engineered for fastening and loosening 18 mm metric nuts and bolts. The 12-point internal profile offers improved alignment on fastener heads and permits engagement at multiple angles, making it easier to operate in confined or awkward spaces. Compatible with standard 1/2" drive ratchets, extensions and breaker bars, this socket is intended as a durable workshop component for general mechanical and automotive maintenance tasks.

Advantages

The 12-point design reduces the need for precise alignment, speeding up repetitive operations and enabling access where a 6-point socket might be difficult to position. The 18 mm size matches common metric fasteners used on engines, chassis and machinery. Built to fit 1/2" drive tools, the socket provides secure attachment to ratchets and extension bars for effective torque transfer. The compact length allows work in tight spaces while maintaining reliable engagement on bolt heads.

Suitable for

• Automotive repair: wheel nuts, engine and suspension components
• Mechanical and industrial maintenance: machinery bolts and fasteners
• Workshop tasks: assembly, disassembly and general servicing with 1/2" drive tools
• Use with ratchets, breaker bars and torque adapters

Key specifications

• Socket size: 18 mm
• Internal profile: 12-point
• Drive connection: 1/2" (square drive)
• Intended fastener type: metric nuts and bolts
• Typical use: manual torque application with ratchet or breaker bar

How to use

Select the 18 mm 12-point socket when the fastener head matches the size and when multiple engagement angles are beneficial. Attach the socket securely to a compatible 1/2" drive ratchet, extension or breaker bar. Place the socket squarely over the fastener head and apply steady torque, taking care to maintain alignment. For removal of rusted or seized fasteners, use controlled force and, if needed, increase leverage with a breaker bar or use penetrating lubricant before attempting high torque.

Usage recommendations

Inspect the socket and drive tool before use for damage or wear. Use the socket only with hand tools rated for the required torque; avoid impact tools unless the socket is specifically rated for impact use. Store the socket in a protective case or organizer to prevent corrosion and preserve the 12-point profile for accurate engagement.
