Socket bit 1/2" 15 mm long — Proxxon PR23360

Proxxon PR23360 is a 1/2" hexagonal long socket bit with an internal width of 15 mm, designed to fit compatible 1/2" drives. The extended length allows easier access to recessed fasteners and bolts in automotive, workshop and maintenance environments where standard sockets may not reach. Constructed for torque transmission with a conventional hex shape, the socket bit is intended for use where a 15 mm interface and additional reach are required.

Advantages

The long 15 mm socket provides improved reach compared with standard-length sockets, enabling work on fasteners located in narrow recesses or behind obstructions. Its 1/2" drive interface ensures compatibility with a wide range of ratchets, extensions and torque tools, while the hexagonal interior delivers reliable contact with 15 mm fastener heads to reduce slipping and rounding. The design balances access and torque transfer for routine mechanical and maintenance tasks.

Suitable for (tasks / use cases)

• Automotive repair and maintenance — wheel nuts, engine bay bolts in recessed positions
• General workshop use — assembly, disassembly and maintenance of machinery
• HVAC and appliance service where fasteners are set back from the work surface
• Construction and installation tasks that require added reach with a 15 mm socket

Key specifications

• Drive size: 1/2" compatible
• Internal width: 15 mm
• Style: hexagonal (6-point) interior
• Form factor: long / extended length socket bit
• Intended use: access to recessed or hard-to-reach fasteners

How to use

Select a compatible 1/2" drive ratchet, breaker bar or extension and attach the Proxxon 15 mm long socket bit securely to the drive. Position the hex socket over the 15 mm fastener head, ensuring full seating before applying torque. Turn the drive tool slowly at first to confirm correct engagement, then apply steady torque appropriate to the fastener and application. Use extensions or universal joints as needed to reach awkward angles, and avoid excessive force that could damage fasteners or the socket.

Usage recommendations

Inspect the socket for wear or rounding before use, and match torque settings to fastener specifications. Store the socket in a dry tool case to prevent corrosion and use the long socket only where extra reach is required to avoid unnecessary leverage on fasteners.
