Schroevendraaierbit TORX Wera 867/4 Z TX 15 4 mm 70 mm

Wera TORX screwdriver bit 867/4 Z TX 15 is a single TX15 bit with a 4 mm shank diameter and 70 mm length. It is engineered for use with bit holders and power drivers to ensure precise engagement with TORX fasteners and efficient torque transfer. The bit’s overall dimensions and geometry make it suitable for assembly, repair and maintenance tasks that require a TX15 drive.

Advantages

The bit features hardened and wear-resistant steel to withstand repeated use and provide consistent fit in TORX recesses. Its 4 mm shank diameter ensures compatibility with standard bit holders and quick-change chucks. The 70 mm length gives improved access to recessed or slightly obstructed fasteners while maintaining control and stability during high-torque operations.

Suitable for

• Electronics assembly and small appliance repair requiring TX15 fasteners
• Automotive interior and trim work where TORX TX15 is specified
• Furniture assembly and maintenance with recessed TORX screws
• General maintenance tasks in workshops and production lines

Key specifications

• Drive type: TORX TX15
• Shank diameter: 4 mm
• Overall length: 70 mm
• Material: hardened tool steel (wear-resistant)
• Compatibility: for use with bit holders, bit sockets and power drivers

How to use

Insert the 4 mm shank into a compatible bit holder or quick-change chuck until it locks securely. Align the TORX TX15 tip with the fastener head and apply steady axial pressure while turning with a manual driver or engaging the power driver at controlled torque settings. For power tools, start at low speed to ensure correct seating, then increase speed or torque as required by the application. Withdraw the bit straight out of the fastener to avoid cam-out and inspect the tip periodically for wear.

Recommendations

Use appropriate torque settings on powered drivers to avoid damaging TORX fasteners. Keep the bit clean and free of debris; replace the bit if the tip shows rounding or chipping to maintain reliable engagement and prevent fastener damage.
