Socket wrench Proline 1/2" 6-point 19 mm model 9017777

Proline 1/2" 6-point 19 mm socket wrench (model 9017777) is a durable hand tool for fastening and loosening hexagonal nuts and bolts. Designed with a 1/2" drive, it fits standard ratchets and torque wrenches used in automotive, workshop and maintenance applications. The socket is manufactured from chrome-vanadium steel and undergoes precise hardening and tempering to ensure the required hardness and long service life.

Advantages

The 6-point design provides secure engagement with fastener heads to reduce rounding. Chrome-vanadium construction and controlled heat treatment exceed DIN 3124 and PN-ISO 1711 strength requirements. Edges between contact faces are specially profiled with the PRO-DRIVE system to reduce concentrated stress on fastener corners and protect bolt heads and flat surfaces from excessive wear.

Suitable for

• Automotive repair and maintenance
• General workshop and mechanical tasks
• Assembly and repair where a reliable 19 mm socket is required

How to use

Select the 19 mm socket and attach it to a compatible 1/2" ratchet or torque wrench. Place the socket fully onto the nut or bolt head, ensuring correct seating on the fastener flats, then apply turning force in the required direction. For torque-controlled operations, use a calibrated torque wrench and follow the specified torque values for the application.

Usage recommendations

Inspect the fastener and socket faces for damage before use, keep the socket clean and lightly lubricated if needed, and avoid excessive impact loads. Use the appropriate torque settings and a properly sized 6-point socket to minimize fastener rounding and extend tool life.
