Screwdriver Bit Wera 867/4 Z SB

The Wera 867/4 Z SB screwdriver bit is a Torx Plus TX15 bit designed for precision fastening in professional environments. With a length of 152 mm and a 1/4" hexagonal shank, this bit extends reach into recessed fasteners and is compatible with a wide range of bit holders and hand or power tools accepting 1/4" bits. The Torx Plus profile improves torque transfer and reduces cam-out compared with conventional profiles, while the bit’s construction emphasizes durability and consistent fit at the screw head.

Advantages

This Torx Plus TX15 bit provides secure engagement with Torx Plus fasteners, allowing higher torque transmission and reduced wear on both bit and screw. The 152 mm length gives extra reach for recessed or awkwardly positioned screws. The 1/4" hexagonal shank ensures stable mounting in standard bit holders, quick-change chucks, and impact-rated adapters. Packaged in a blister, the bit is easy to store and identify in toolkits.

How to use

Select the Torx Plus TX15 bit and insert the 1/4" hexagonal shank into a compatible bit holder, quick-change chuck, or hand driver. Ensure the bit is fully seated and secured before applying torque. For power tool use, set an appropriate torque or clutch setting to avoid over-tightening. When accessing recessed screws, extend the bit fully and keep the tool axis aligned with the fastener to maintain engagement and prevent slippage. After use, store the bit in its blister or in a designated bit organizer to protect the tip and maintain fit.

Usage recommendations

For longest service life and consistent performance, use the Wera Torx Plus TX15 bit with the correct fastener profile, avoid side loads, and pair with suitable torque-controlled drivers. Inspect the tip regularly for wear and replace when rounding or damage is visible to prevent damage to fasteners and ensure safe, accurate fastening.
