## Long description

The Wera 840/4 Z SB screwdriver bit is a precision hex bit designed for reliable fastening tasks. It has a 5 mm hex tip and a hardened shaft with a total length of 152 mm, paired with a 1/4 inch hexagonal shank for compatibility with common bit holders and drivers. Supplied in a blister pack, this bit delivers a secure fit in socket adapters and quick-change chucks and is intended for repeatable, accurate torque transfer in workshop and maintenance environments.
Advantages
The bit combines precise tip geometry with durable material treatment to reduce wear and cam-out. Its 5 mm hex tip provides accurate engagement with fasteners, while the 152 mm length gives added reach for recessed or hard-to-access screws. The 1/4 inch hexagonal shank ensures compatibility with a wide range of manual and powered drivers. The blister packaging protects the bit during transport and storage.

Key specifications
Tip type: 5 mm hexagon
Total length: 152 mm
Shank shape and size: 1/4 inch hexagonal shank
Material and treatment: hardened steel tip and shaft for wear resistance
Packaging: blister pack for individual protection
How to use
Insert the 1/4 inch hex shank into a compatible bit holder, quick-change chuck, or screwdriver handle. Ensure the bit is fully seated and locked before applying torque. Use steady pressure and align the bit with the fastener axis to minimize slipping. For powered drivers, select an appropriate speed and torque setting to match the fastener and workpiece material. After use, return the bit to its blister pack or store in a suitable holder to prevent damage.
Usage recommendations
Inspect the bit tip before each use for rounding or damage; replace the bit if wear compromises engagement. Use the bit with drivers that accept a 1/4 inch hex shank and match torque settings to the fastener size. Avoid using the bit as a pry tool or subjecting it to lateral loads that can cause breakage.
