Proline Key Gala 3/4 46mm 5188465 screwdriver bit set — 46 mm length, 3/4 drive

Proline Key Gala 3/4 46 mm (model 5188465) is a 46 mm long screwdriver bit designed for use with 3/4 drive tools. The bits are made from chromium-vanadium steel and undergo precise hardening and tempering to achieve the required hardness and durability. The tool meets and exceeds durability requirements of DIN 3124 and PN-ISO 1711 and is intended for reliable torque transfer in fastening applications.

Advantages

The Proline Key Gala bits feature specially profiled edges between the working faces — the PRO-DRIVE system — which reduces concentrated point loads on screw heads and helps protect against rounding and excessive wear. Chromium-vanadium construction and controlled heat treatment provide consistent hardness, improved wear resistance and long service life when used within specified operating conditions.

Suitable for

• General fastening tasks with a 3/4 drive interface
