Socket bit hex 1/2" Proxxon H12 x 55 mm, model PR23481

Proxxon Socket bit hex 1/2" H12 x 55 mm is a single-piece hex socket accessory designed for use with 1/2" drive tools. It features a 12 mm hex profile and a 55 mm overall length, providing a compact yet accessible reach for fastening and loosening hex bolts and screws in workshop, maintenance, and mechanical repair environments.

Advantages

The socket bit is manufactured to fit standard 1/2" drive tools and deliver a secure connection between tool and fastener. Its 12 mm hex profile ensures accurate engagement with hex heads, reducing rounding and slippage. The 55 mm length balances access to recessed fasteners with the control offered by a short extension. Material and machining provide a durable contact surface suitable for repeated professional and DIY use.

Suitable for

• Workshop assembly and disassembly of machinery and equipment
• Automotive and bicycle maintenance where 12 mm hex fasteners are used
• General mechanical repairs and installations requiring a 1/2" drive
• Use with torque-controlled tools in maintenance tasks

Key specifications

• Drive connection: 1/2" drive
• Hex size: 12 mm
• Overall length: 55 mm
• Type: hex (hexagon) socket bit
• Compatibility: designed for standard 1/2" sockets and extensions

How to use

Attach the socket bit to a compatible 1/2" drive ratchet, breaker bar, or torque wrench until it seats securely. Position the hex end onto the fastener head, ensuring full engagement before applying torque. For tight or stuck fasteners, apply steady, controlled force and avoid sudden impacts that could damage the bit or fastener. After use, inspect the hex profile for wear and store the bit in a dry, organized tool set to maintain fit and function.

Usage recommendations

Use the socket bit with tools rated for the required torque and avoid exceeding recommended torque limits for the fastener material. Select the correct 12 mm fit to prevent rounding. Clean and lightly lubricate fasteners if corrosion is present before applying high torque.
