Screwdriver bit Wera 867/4 KK Torx Plus TX10 1/4" hex shank, 89 mm, 1 pc

The Wera 867/4 KK Torx Plus TX10 screwdriver bit is a single-piece precision bit with an overall length of 89 mm and a 1/4" (6.35 mm) hexagonal shank designed for standard bit holders and ratchets. Manufactured from tough alloy tool steel in the Czech Republic, this bit is intended for use with Torx Plus fasteners and provides a reliable fit for maintenance, assembly and repair tasks that require the specific TP profile. The bit’s geometry supports engagement with recessed TORX® screw heads and is compatible with holder systems conforming to DIN ISO 1173-F 6.3.

Advantages

The Wera 867/4 KK combines hardened alloy tool steel construction and precise Torx Plus profile to deliver durable wear resistance and consistent fit in Torx Plus screw heads. Its 1/4" hex shank ensures compatibility with common bit holders and compact ratchets, while the 89 mm length gives extra reach for recessed or slightly obstructed fasteners. The ballpoint-style capability allows the tool axis to be angled slightly away from the screwdriving axis for access in confined or offset positions.

Suitable for

• Repair and maintenance work involving Torx Plus (TP) fasteners
• Assembly tasks where a 1/4" hex bit holder or compact ratchet is used
• Accessing recessed or awkwardly positioned Torx Plus screws due to extended length
• Situations requiring some angular approach using the ballpoint drive feature

When it may not be suitable

This single Torx Plus TX10 bit is not suitable when multiple bit sizes or a set of bits is required for varied fastener types; users who need different tip profiles or larger torque delivery should select a different size or additional tools. It is also not intended as a standalone handle; a compatible 1/4" bit holder, adaptor or ratchet is required for use.

Key specifications

• Tip type: Torx Plus (TX10)
• Shank: 1/4" hexagonal (6.35 mm)
• Length: 89 mm
• Material: tough alloy tool steel
• Suitable holder standard: DIN ISO 1173-F 6.3 compatibility

How to use

Insert the 1/4" hex shank of the bit into a compatible bit holder, adaptor or ratchet, ensuring secure seating. Align the Torx Plus tip with the corresponding fastener head and apply steady axial pressure while driving to maintain full engagement of the TP profile. For constrained angles, use the ballpoint capability to approach the screw with a slight offset; reduce torque if slipping or cam-out is observed and reposition the bit for correct alignment.

What to consider before purchase

• Ensure the fasteners to be used are Torx Plus (TP) and specifically TX10 size.
• Confirm compatibility with your existing 1/4" bit holders or ratchets.
• Assess whether a single bit meets your needs or if a set with multiple sizes is required.

Usage recommendations

Use the Wera 867/4 KK in combination with a properly rated holder and apply controlled torque; avoid excessive side loads to prolong bit life and maintain accurate engagement with Torx Plus fasteners.
