Screwdriver Bit Wera T30 L 25mm BiTor 867/1BTZ zähhart C6.3 – Torx T30 25 mm

Wera BiTor 867/1BTZ zähhart C6.3 is a hardened screwdriver bit designed for precise engagement with Torx T30 fasteners. At 25 mm length, this bit is intended for use with bit holders, ratchets and powered drivers where a compact profile and reliable torque transfer are required. The BiTor geometry provides increased contact area at the tip, reducing wear and minimizing cam-out during repeated fastening operations.

Advantages

The hardened steel construction delivers extended service life under frequent use and high torque. The BiTor tip geometry improves fit to Torx T30 heads, which helps reduce rounding and slipping. Its 25 mm length enables access to recessed screws and makes the bit suitable for use in tight assembly spaces. The C6.3 shank size ensures compatibility with common bit holders and quick-change adapters.

Suitable for

• Assembly and disassembly of Torx T30 fasteners in mechanical systems
• Maintenance and repair tasks with limited access or recessed screws
• Use with bit holders, powered drivers and manual handles requiring a 25 mm bit
• Repeated fastening operations where reduced wear and precise fit are important

Key specifications

• Type: Torx T30 screwdriver bit
• Length: 25 mm
• Material hardness: hardened (zähhart) steel
• Tip geometry: BiTor for improved contact and reduced cam-out
• Shank form: C6.3 compatible with standard 1/4" bit holders

How to use

Insert the 25 mm Torx T30 bit into a compatible bit holder, quick-change adapter or directly into a powered driver with a C6.3-compatible chuck. Ensure the bit is seated fully to maintain correct tip engagement. Apply steady axial pressure while driving or loosening fasteners to keep the BiTor tip engaged and reduce the risk of slippage. Inspect the bit tip periodically for wear and replace when the profile becomes rounded or damaged to maintain safe and effective operation.

Usage recommendations

Use appropriate torque settings on powered tools to avoid overloading the bit and fastener. For high-torque applications, pair the bit with a driver and holder rated for the required torque and inspect seating before each use. Store bits in a dry, organized holder to prevent corrosion and tip damage.
