Socket key 1/2" 6-point 15 mm Proline 9017739

Socket key 1/2" 6-point 15 mm Proline 9017739 is a 1/2" drive, 6-point socket designed for tightening and loosening 15 mm hex fasteners. It is intended for use with 1/2" ratchets and torque tools and offers a precise fit on nuts and bolts commonly found in automotive, maintenance and assembly tasks.

Advantages

The socket is manufactured from chrome-vanadium steel and undergoes precise hardening and tempering processes to ensure required hardness and durability. Its strength characteristics exceed DIN 3124 and PN-ISO 1711 standards. A specially profiled edge between the contact faces — the PRO-DRIVE system — reduces concentrated point loading and helps protect fastener heads and flat edges from excessive wear.

Suitable for

• Automotive repair and maintenance
• Mechanical assembly and disassembly
• Workshop and industrial maintenance tasks

How to use

Fit the 1/2" drive socket onto a compatible ratchet or torque tool, place the 6-point opening fully onto the 15 mm fastener, and apply torque in the required direction to tighten or loosen. Ensure correct seating of the socket on the fastener before applying high torque to avoid slippage. Use appropriate torque settings when required by manufacturer specifications.

Usage recommendations

For longer tool life and optimal protection of fasteners, keep the socket clean and dry, avoid impact use beyond specified limits, and store in a dry toolbox. Replace the socket if edges become rounded or damaged.
