Ruuvauskärki Torx Wera TX 40 × 25 mm 05066110001

Wera Torx screwdriver bit TX 40 × 25 mm is a precision-made exchangeable bit designed for reliable engagement with TX 40 fasteners. Manufactured by Wera, this 25 mm length bit suits use in bit holders, cordless drivers and manual screwdrivers that accept standard insert bits. The compact length provides access to moderately recessed Torx heads while keeping a positive fit that reduces cam-out and improves torque transfer during fastening and removal.

Advantages

The bit is produced to tight dimensional tolerances for consistent seating in Torx sockets, offering stable torque transmission and reduced wear on both bit and fastener. Its 25 mm length balances reach and control, making it convenient for confined workspaces without excessive overhang. Compatibility with common hex-shank bit holders and quick-change chucks ensures straightforward interchangeability in professional and DIY toolkits.

Suitable for

• Assembling and disassembling components with TX 40 Torx heads
• Use with cordless screwdrivers and impact drivers that accept exchangeable bits
• Maintenance tasks in automotive, machinery and equipment repair where moderate recess depth is present
• Work in workshops and on-site jobs requiring compact, accurate bits

Key specifications

• Bit type: Torx (TX)
• Size: TX 40
• Length: 25 mm working length
• Drive interface: standard hex shank compatible with bit holders and quick-change chucks
• Material and finish: hardened tool steel with precision-machined tip for accurate fit (manufacturer standard)

How to use

Select a compatible bit holder or driver chuck and insert the TX 40 × 25 mm bit securely. Align the bit with the fastener head and apply steady axial pressure while driving to maintain full contact between the tip and Torx recess. Use appropriate torque settings on power drivers to avoid over-torquing; for manual work, maintain controlled force and gradual tightening. Remove the bit after use, clean any debris from the tip and store in a bit case or holder to prevent damage.

Recommendations

For best results, use with drivers that accept exchangeable bits and select torque or clutch settings appropriate to the material and fastener to minimize wear. Inspect the bit tip regularly for rounding or damage and replace when fit becomes loose to avoid damaging Torx fasteners.
