Socket Bit Hex 1/2" H5 x 55 mm Proxxon PR23476

Proxxon PR23476 is a 1/2" drive hex socket bit with H5 size and 55 mm length, intended for use with 1/2" ratchets and torque tools. The tool is engineered to provide precise engagement with H5 hex fasteners while offering extended reach compared with standard-length bits. Its straight hex profile and measured length make it appropriate for tasks requiring accurate torque application and access into recessed or partially obstructed fastener locations.

Advantages

This hex socket bit delivers accurate fitment to H5 hex fasteners, reducing rounding and slip. The 55 mm length increases working reach, allowing access to deeper or recessed bolts without additional extensions. Built for compatibility with 1/2" drive tool interfaces, it supports the transfer of controlled torque from ratchets and torque wrenches. The tool’s geometry ensures reliable engagement and predictable force transmission during tightening and loosening operations.

Suitable for

• Mechanical assembly and disassembly where H5 hex fasteners are used
• Automotive repair tasks requiring extended reach into tight engine or chassis areas
• Maintenance and service work on equipment with recessed or hard-to-access hex bolts
• Controlled torque applications with 1/2" torque wrenches and ratchets

Key specifications

• Drive size: 1/2" compatible
• Hex size: H5 (hexagonal internal profile sized for H5 fasteners)
• Overall length: 55 mm usable length for extended reach
• Profile: internal hex socket designed for precise engagement
• Intended use: manual ratchet and torque tool operation

How to use

Attach the hex socket bit securely to a compatible 1/2" drive ratchet or torque wrench. Align the internal hex profile with the H5 fastener, ensuring full seating before applying force. For tightening, apply torque progressively and monitor the applied value when using a torque wrench; for loosening, apply steady controlled force to avoid rounding the fastener. Remove the bit after use and inspect the engagement surfaces for wear or deformation before subsequent operations.

Usage recommendations

Use the socket bit with properly rated 1/2" drive torque tools and ratchets. Avoid excessive impact loads if the bit is not specified for impact use. Keep contact surfaces clean and ensure correct seating to minimize wear and prevent damage to hex fasteners.
