## Long description

The Wera 851/4 Z SB screwdriver bit is a precision Phillips PH2 bit designed for extended-reach fastening tasks. With a total length of 152 mm and a hexagonal shank sized 25.4 / 4 mm (1 / 4"), this bit provides a secure interface with bit holders and drivers while allowing access to recessed or hard-to-reach screws. Packaged in a blister, it is intended for professional use as well as careful DIY applications where accuracy and fit are important.
Advantages
The bit is manufactured to deliver a consistent Phillips profile that reduces cam‑out and improves torque transfer. Its 152 mm length enables work in deeper or confined spaces without compromising control. The hexagonal shank ensures solid retention in standard 1/4" bit holders and quick-change adapters. The durable material and precision machining provide long service life under regular use.

How to use
Insert the hexagonal shank into a compatible 1/4" bit holder, quick-change adapter, or screwdriver handle. Align the Phillips PH2 tip with the screw head and apply steady axial pressure while turning the driver to reduce the risk of cam‑out.

Usage recommendations

Store the bit in its blister or a dedicated bit organizer to avoid corrosion and tip damage.
