Screwdriver Bit Wera T15 L 25 mm BiTor 867/1BTZ zähhart — Torx T15, 25 mm

Wera BiTor T15 L 25 mm zähhart screwdriver bit is a single Torx T15 tip engineered for secure engagement and extended wear resistance. At 25 mm length, this bit fits most standard bit holders for manual and powered screwdrivers and is designed to provide consistent torque transfer to Torx fasteners. Manufactured with a hardened material and BiTor geometry, the bit aims to reduce cam-out and increase life under repetitive use in assembly, maintenance, and repair tasks.

Advantages

The BiTor geometry offers improved contact between driver and fastener head, reducing the risk of rounding and slipping. The zähhart (tough-hard) heat treatment increases surface hardness and toughness to resist wear during repeated driving operations. Its 25 mm length provides a balance between reach and control for both hand-held and machine-driven applications. The single-bit form factor simplifies storage and quick replacement in modular bit holders.

Suitable for

• Driving Torx T15 fasteners in electronics assembly
• Maintenance and repair of appliances and equipment
• General assembly work where compact bit length is required
• Use with manual screwdrivers and powered drivers with compatible bit holders

Key specifications

• Tip type: Torx T15
• Length: 25 mm
• Material treatment: zähhart (hardened/toughened)
• Geometry: BiTor improved contact profile
• Compatibility: standard 1/4" bit holder systems

How to use

Insert the 25 mm Torx T15 bit into a compatible 1/4" bit holder or directly into a screwdriver with a magnetic or locking bit socket. Align the Torx tip with the fastener recess and apply steady axial pressure while turning the driver to avoid cam-out. For powered drivers, use controlled torque settings appropriate for the fastener and material to prevent over-tightening. Inspect the bit tip periodically for wear and replace it when the profile shows signs of rounding.

Usage recommendations

For best results, use the BiTor T15 bit with matched Torx fasteners and appropriate torque settings. Avoid using a damaged or excessively worn tip to prevent fastener damage. Store the bit in a dry place and keep it in a proper bit organizer to maintain tip geometry and prevent corrosion.
