Screwdriver Bit Proline Key Gala 1/2 T45 9040843, 1/2" square drive, Torx T45

Proline Key Gala 1/2 T45 (model 9040843) is a screwdriver bit made from CR‑V S2 steel for use with a 1/2" square drive and Torx T45 fasteners. It is designed to provide a precise fit for Torx T45 screws and withstand higher torque during assembly, maintenance and repair tasks. The 55 mm length allows access to recessed fasteners when used with compatible sockets, adapters or impact-capable drivers.

Advantages

The bit is manufactured from CR‑V S2 steel for durability and resistance to wear. Its exact Torx T45 profile reduces cam‑out and improves torque transfer. The 1/2" square end ensures secure attachment to sockets or adapters, and the 55 mm length offers reach for recessed screws. The design is suitable for use with impact drivers when matched with appropriate holders.

Suitable for

• Assembly of furniture and equipment requiring Torx T45

How to use

Insert the 1/2" square end of the bit into a compatible socket, adapter or bit holder. Engage the Torx T45 tip fully into the screw head to ensure a secure fit before applying torque. For power tools, use an impact‑rated holder and set the driver to the appropriate torque to avoid over‑tightening. After use, inspect the bit for wear and store it in a dry place.

Usage recommendations

Use with impact‑rated holders when applying high torque, avoid side loading, and replace the bit if the Torx profile shows rounding to maintain fit and safety.
