Hex Socket Bit 1/2" Proxxon PR23478 H7 x 55 mm

Proxxon Hex Socket Bit 1/2" PR23478 H7 x 55 mm is a medium-length hex (Allen) socket bit designed for use with 1/2" drive ratchets, torque wrenches and socket handles. The bit provides a secure H7 hex interface for fastening and disassembly tasks in workshop, automotive and equipment maintenance environments. Its 55 mm length offers a balance between access into recessed fasteners and controlled torque transmission for routine mechanical work.

Advantages

The hex socket bit combines a standard 1/2" drive connection with a precise H7 hex profile to ensure reliable engagement with hex fasteners. Its medium length improves reach without sacrificing control, and the hardened driving end resists wear under repeated use. The tool is compatible with common workshop torque tools and socket accessories, supporting consistent torque application and safe removal of hex bolts and screws.

Suitable for

• Mechanical assembly and disassembly of machinery and equipment
• Automotive repair tasks requiring medium-reach hex access
• Workshop and maintenance operations using 1/2" drive tools
• Servicing industrial components with H7 hex fasteners

Key specifications

• Drive size: 1/2" compatible drive
• Hex size: H7
• Overall length: 55 mm
• Type: Hex (Allen) socket bit
• Application: Medium-length bit for access to recessed fasteners

How to use

Fit the hex socket bit into a compatible 1/2" drive ratchet, torque wrench or socket handle until it seats securely. Align the H7 hex profile with the corresponding fastener and apply steady torque while maintaining axial alignment to avoid rounding the hex. For torque-sensitive applications, use a calibrated torque wrench and apply the manufacturer-recommended torque values. After use, clean the bit of debris and store it in a protective holder to prevent damage.

Usage recommendations

Use the bit only with tools rated for 1/2" drive connections and avoid excessive impact loading unless the bit and driving tool are specifically rated for impact use. Regularly inspect the hex profile for wear and replace the bit if rounding or significant deformation is observed to ensure safe and reliable operation.
