Screwdriver Bit Wera Torx 867/4 IMP DC TX25 x 50 mm

Wera Torx 867/4 IMP DC TX25 x 50 mm is a replacement screwdriver bit engineered for Torx TX25 fasteners. As part of Wera’s 867/4 IMP DC series, this 50 mm bit offers extended reach for recessed or narrow fastening points while remaining compatible with standard 1/4" hex bit holders and most impact driver chucks. The bit’s geometry provides a precise fit into Torx heads to reduce cam-out and ensure consistent torque transfer during assembly, maintenance, and repair tasks.

Advantages

The hardened tip and optimized Torx profile ensure accurate seating and longer wear life compared with generic bits. The 50 mm length improves access to screws located in deep or confined areas without sacrificing control. Designed for use with impact drivers, the IMP DC construction absorbs impact stresses while maintaining dimensional stability for reliable performance under repeated heavy use.

Suitable for

• Automotive and motorcycle maintenance
• Electronics assembly and repair where TX25 fasteners are used
• Furniture assembly and household repairs in recessed or tight locations
• Industrial production and maintenance tasks requiring impact-rated bits

Key specifications

• Tip profile: Torx TX25
• Length: 50 mm working length
• Drive interface: 1/4" hex shank compatible with standard bit holders
• Construction: impact-rated bit design suitable for impact drivers
• Material/treatment: hardened and wear-resistant tip for improved durability

How to use

Insert the 1/4" hex shank into the bit holder, magnetic socket, or impact driver chuck until it locks. Align the Torx TX25 tip with the fastener head and apply steady, axial pressure while driving to maintain proper engagement. When using an impact driver, start at low speed to seat the bit and then increase power as needed. Remove the bit by retracting it from the holder once the fastening operation is complete.

Usage recommendations

Use the bit with drivers and holders rated for 1/4" hex impact bits and select appropriate torque settings to avoid fastener damage. Inspect the tip regularly for wear and replace the bit if the Torx profile shows rounding or deformation. Store bits in a dedicated case or rack to protect the tip and ensure long service life.
