Screwdriver Bit Proline Key Gala 3/4 50mm 5188502 – 50 mm length, 3/4 key profile

Proline Key Gala 3/4 50mm (model 5188502) is a 50 mm screwdriver bit with a 3/4 key profile, made from chrome-vanadium steel and heat-treated to achieve the required hardness and durability. The bit exceeds DIN 3124 and PN-ISO 1711 strength requirements and features specially profiled edges between the working faces — the PRO-DRIVE system — to reduce excessive point loading and protect screw heads and flat edges from wear.

Advantages

The Proline Gala bit offers hardened chrome-vanadium construction for increased strength and long service life, compliance with DIN 3124 and PN-ISO 1711 standards, and a PRO-DRIVE profile that improves contact with fasteners and reduces slippage and damage to screw heads. Its 50 mm length provides convenient reach in confined spaces while remaining compatible with common hand and power drivers.

Suitable for

• Assembly of components with 3/4 key profile fasteners
• Maintenance and repair tasks where a compact 50 mm bit is required
• Use with hand drivers and compatible power driver chucks

For power drivers, use controlled speeds and torque settings to avoid stripping or over-torquing the screw head.

Usage recommendations

Store the bit in a dry place to prevent corrosion and inspect the tip before use; replace the bit if the working faces show significant wear or rounding to ensure reliable engagement and to protect fastener heads.
