Bit Torx FELO TX40 50 mm – FELO TX40 50mm star (Torx) screwdriver bit

FELO Torx TX40 50 mm screwdriver bit is a precision-made star-profile bit designed for reliable engagement with Torx fasteners. With a 50 mm shaft length, this FELO TX40 50mm star (Torx) screwdriver bit is intended for use in compatible bit holders, manual screwdrivers that accept replaceable bits and many cordless or corded power drivers. The TX40 profile ensures stable torque transfer and reduced cam-out when working with Torx fasteners used in assembly, maintenance and repair applications.

Advantages

The FELO TX40 50 mm bit combines hardened steel geometry with a precisely formed Torx tip to provide consistent fit and wear resistance during repeated use. Its 50 mm length offers better reach into recessed or partially obstructed fastener locations compared with shorter bits. The star (Torx) profile improves contact area and reduces slippage under higher torque loads, making it suitable for both manual and machine-driven fastening tasks.

Suitable for

• Assembly of mechanical components and furniture where TX40 fasteners are specified
• Maintenance and repair of automotive and machinery parts using Torx screws
• Work on electronic housings, enclosures and panels that require TX40 drivers
• Use with bit holders, magnetic adapters and compatible power tools for medium to high torque fastening

Key specifications

• Bit type: Torx (star) TX40 tip
• Overall length: 50 mm
• Compatibility: standard 1/4" hex drive bit holders and compatible screwdriver handles
• Typical use: manual and power tool fastening of Torx TX40 screws
• Material characteristics: hardened tip geometry for wear resistance (manufacturer standard)

How to use

Insert the 1/4" hex end of the FELO TX40 50 mm bit into a compatible bit holder, magnetic adapter or screwdriver handle. Align the Torx TX40 tip with the screw head and apply steady axial pressure while turning the driver to avoid cam-out. For power tool use, select appropriate torque and speed settings recommended for the fastener and material to prevent over-tightening or damage. After use, store the bit in a suitable bit case or holder to protect the tip geometry.

Usage recommendations

Use the FELO TX40 50 mm bit for tasks requiring precise Torx engagement and moderate reach. Inspect the tip for wear before critical operations and replace the bit if rounding or damage is visible. When using power tools, begin with lower torque settings and increase gradually as needed to match the fastener and workpiece material.
