Socket Key 1/4" 13 mm Proline 9017654 for 1/4" Drive Sockets

Proline Socket Key 1/4" 13 mm (model 9017654) is a 13 mm socket designed for use with 1/4" drive ratchets and handles. Manufactured from chrome-vanadium steel and subjected to controlled hardening and tempering, this socket delivers the hardness and durability required for repeated mechanical use. The socket conforms to and exceeds the strength requirements of DIN 3124 and PN-ISO 1711 and is compact for working in confined spaces.

Advantages

The 13 mm socket features specially profiled edges between the contact faces — the PRO-DRIVE system — to reduce concentrated point loads on fastener heads and limit wear on flat edges. Its chrome-vanadium construction and heat treatment give reliable resistance to mechanical stress while maintaining compatibility with standard 1/4" drive accessories.
