Screwdriver bit Wera 867/1 Z TORX BO — Torx tip, 1/4" drive, 25 mm length

Single Wera 867/1 Z TORX BO screwdriver bit with a Torx tip, 1/4" hex drive and 25 mm overall length. The bit is designed for use with bit holders, ratchets and electric drivers that accept 1/4" hex shanks. It is intended for fastening TORX BO (security Torx) screws commonly found in electronics, appliances and general assembly work, providing a secure fit between bit and screw head.

Advantages

The bit features a TORX BO profile with a central hole for engaging the screw's security pin, enabling positive engagement and preventing unauthorized loosening. Manufactured for toughness and universal use, the 1/4" hex shank is compatible with tools conforming to DIN ISO 1173-D 6.3. Its 25 mm length provides good reach in confined spaces while maintaining control and torque transfer.

Suitable for

• Fastening and removing security Torx (TORX BO) screws in electronic devices
• Repair and assembly of household appliances and consumer electronics
• General mechanical and assembly work where a 1/4" hex bit holder or driver is used
• Service and maintenance tasks requiring a secure anti-tamper connection

Key specifications

• Tip type: TORX BO (security Torx) compatible with pin-in Torx screws
• Drive: 1/4" hex shank suitable for bit holders and drivers
• Length: 25 mm overall
• Material/finish: hardened tool steel for durability and torque resistance
• Standards compatibility: fits tools per DIN ISO 1173-D 6.3

How to use

Insert the 1/4" hex shank into a compatible bit holder, ratchet or electric driver. Align the TORX BO tip with the screw head so the central hole in the bit engages the screw's locating pin. Apply steady axial pressure and rotate the driver to tighten or loosen the screw. Use appropriate torque settings on power tools to avoid cam-out or damage to the screw head and to the bit.

Usage recommendations

For reliable performance, check the bit and screw head for wear before use. Select a bit that matches the screw size precisely. When using powered drivers, set torque limits appropriate for the material to prevent over-tightening. Store bits in a dry place and replace when tip wear reduces engagement quality.
