Socket Key 1/2" 6-point 13 mm Proline 9017715 for hex fasteners

Socket key 1/2" 6-point 13 mm Proline 9017715 is a 6-point socket designed for tightening and loosening hex fasteners. Made from chrome-vanadium steel and subjected to precise hardening and tempering, this socket delivers the required hardness and durability. The tool meets and exceeds strength requirements of DIN 3124 and PN-ISO 1711 and is intended for use with compatible 1/2" drives to transfer torque reliably to bolts and nuts.

Advantages

The Proline 9017715 socket features specially profiled edges between the working faces — the PRO-DRIVE system — which reduces excessive point loads and protects bolt heads and flat edges from premature deformation. Its chrome-vanadium construction and controlled heat treatment ensure long service life and consistent performance under workshop and automotive conditions.

How to use

Select a compatible 1/2" drive ratchet or breaker bar, attach the 13 mm 6-point socket securely to the drive, place it on the hex fastener and apply torque in the required direction to tighten or loosen. Ensure the socket fully seats on the fastener before applying high torque to avoid slippage and potential damage. Use proper extension or universal joint adapters when access is restricted.

Usage recommendations

For best results, inspect the socket and fastener for wear or rounded edges before use. Avoid applying impact tools unless the socket and fastener are rated for such use; store the socket in a dry place to prevent corrosion.
