Socket Key Proline 9033357 1/2" Extended 13 mm

Proline Socket Key 9033357 is an extended 13 mm 1/2" drive socket designed to reach fasteners located in recessed or confined spaces. Made from chrome-vanadium steel and subjected to controlled hardening and tempering, this socket delivers the hardness and durability required for repeated workshop and field use. The tool meets and exceeds the durability requirements of DIN 3124 and PN-ISO 1711 for impact and wear resistance.

Advantages

The socket's chrome-vanadium construction and heat treatment ensure long service life and resistance to wear. Its extended design improves access to deep-set nuts and bolts while the PRO-DRIVE specially profiled contact surfaces reduce point loading on fastener heads, helping to prevent damage and rounding. The 1/2" drive provides compatibility with standard ratchets and impact tools.

Suitable for

• Automotive repair and maintenance
• Assembly and installation in machinery and equipment
• Maintenance work in confined or recessed areas
• Workshop and professional hand tool use

How to use

Select a compatible 1/2" ratchet or drive tool, place the 13 mm socket over the fastener head, and apply turning force in the required direction to tighten or loosen the fastener. Use steady, controlled torque and ensure the socket is fully seated on the fastener before applying force. For impact applications, confirm tool compatibility with impact sockets and use appropriate safety precautions.

Usage recommendations

Inspect the socket regularly for wear or deformation and replace it if the contact surfaces become rounded or damaged. Store in a dry place to minimise corrosion and use appropriate sockets for impact tools when performing high-torque operations.
