## Long description

Wera 855/4 Z SB is a single Torx screwdriver bit designed for use with 1/4" (6.35 mm) shank holders and standard bit sockets. With an overall length of 89 mm and compact 1 pc packaging, this precision bit suits both handheld drivers and powered bit holders for assembly, maintenance, and repair tasks. The Torx tip ensures positive engagement with compatible fasteners and reduces cam‑out risk compared with conventional cross‑head bits.
Advantages
The bit combines a long 89 mm profile with a standard 1/4" shank for improved reach in recessed or narrow access points while maintaining compatibility with common bit holders and drivers. Its Torx tip provides accurate torque transfer and stable seating on fasteners. Lightweight and single‑piece packaged, it is convenient to store and transport, and it integrates easily into tool sets or modular bit systems.
Suitable for
Precision assembly and electronics where controlled engagement is required
Maintenance and repair of machinery or equipment with Torx fasteners

Key specifications
Tip type: Torx
Overall length: 89 mm
Shank diameter: 1/4" (6.35 mm)
Quantity: 1 piece
Weight: approximately 22 g
How to use
Insert the 1/4" shank into a compatible bit holder or driver until it seats securely. Align the Torx tip with the matching fastener and apply steady axial pressure while turning the driver to engage the screw head. For powered tools, select appropriate speed and torque settings to avoid over‑tightening. After use, store the bit in its packaging or in a dedicated bit holder to protect the tip profile.
Usage recommendations
Use the bit with properly sized Torx fasteners to maintain tip geometry and avoid accelerated wear. When working in tight or deep recesses, use controlled torque and avoid side loading to preserve bit life. Replace the bit if any rounding or deformation of the tip becomes visible.
