Screwdriver bit FELO TX40 25 mm — Torx bit for power and manual drivers

FELO TX40 25 mm screwdriver bit is engineered for reliable engagement with Torx (TX40) fasteners. With a 25 mm working length and a standard 1/4" hex shank, this bit fits most manual and powered drivers as well as bit holders. It is intended for assembly, maintenance and repair tasks where precise torque transfer and repeatable seating into the screw recess are required.

Advantages

This Torx bit provides accurate fit and reduced cam-out thanks to its precisely formed tip. The 25 mm length balances access and control, making it suitable for recessed screws and confined spaces while maintaining stable contact during high-torque applications. Compatibility with 1/4" hex chucks and bit holders ensures straightforward interchangeability between hand drivers and power tools. The bit is manufactured to resist wear during repeated use, preserving drive geometry for consistent performance.

Suitable for

• Assembly of electronic and mechanical components using TX40 fasteners
• Maintenance and repair work on machinery, appliances and furniture
• Automotive and industrial applications requiring Torx TX40 drive
• Use with cordless and corded drivers, ratchets and bit holders

Key specifications

• Drive type: Torx TX40
• Length: 25 mm working length
• Shank: 1/4" hex compatible
• Applicable tools: manual screwdrivers, bit holders, power drivers
• Material and finish: engineered for wear resistance and precise tip geometry

How to use

Insert the 1/4" hex shank into the driver chuck or bit holder until it seats securely. Align the TX40 tip with the Torx screw recess, apply light axial pressure and engage the driver at low speed to ensure correct seating. Increase torque gradually when using power drivers to avoid stripping the screw head. After use, store the bit in a protective case or bit rack to preserve tip geometry and prevent corrosion.

Usage recommendations

For best results, match the bit to clean, undamaged Torx screw heads and use a driver with adjustable torque when working with sensitive materials. Inspect the tip regularly for signs of wear and replace the bit if the tip shows rounding or deformation to maintain secure engagement and prevent fastener damage.
