FELO Torx bit TX40 73 mm (FL03640710) - replacement screwdriver bit, hardened steel

FELO Torx bit TX40, 73 mm (replacement screwdriver bit) is a single Torx bit designed for secure engagement with TX40 fasteners. The 73 mm length gives extra reach for recessed or hard-to-access screws, while the hardened steel construction ensures durability and consistent torque transfer during assembly, maintenance and repair tasks. This bit is compatible with standard bit holders and screwdriver handles that accept replaceable bits.

Advantages

The hardened steel tip resists wear and preserves the Torx profile for longer service life. The 73 mm length improves accessibility when working in narrow or deep recesses. Precision machining of the Torx geometry reduces cam-out and ensures stable contact with fasteners, supporting efficient and controlled torque application.

Suitable for

• Assembly of furniture and fittings where TX40 fasteners are used
• Maintenance and repair of machinery and equipment with Torx screws
• Woodworking and metalwork tasks requiring accurate screw driving
• Household repairs and DIY projects that need a longer reach bit

Key specifications

• Bit type: Torx TX40
• Length: 73 mm
• Material: hardened steel
• Compatibility: for use with standard bit holders and replaceable-bit screwdrivers
• Finish: precision-machined tip

How to use

Insert the FELO TX40 bit into a compatible bit holder or screwdriver chuck until it seats securely. Align the bit with the screw head and apply steady axial pressure while turning to prevent slipping. Use appropriate torque settings on powered drivers to avoid over-tightening; for manual use, apply steady, controlled force. After use, store the bit in a protective case or bit holder to prevent damage to the tip.

Usage recommendations

For best results use the TX40 bit with drivers and holders that match the bit shank and intended torque. Avoid excessive sideways force that can deform the Torx profile; replace the bit if the tip shows visible wear or rounding to maintain secure engagement and reduce the risk of fastener damage.
