Effortless fastening in tight spaces

Practical benefits

Ball-end for angled driving: The spherical ballpoint profile allows you to pivot the tool off-axis, making screwdriving in awkward corner positions straightforward.
Tough Wera bit core: Designed with tough-viscous steel, it prevents premature tip breakage when you fasten into hard materials.
Extended reach for depth: With an 89 mm length and standard 1/4" drive, you comfortably reach deeply recessed hexagon socket screws.

In a nutshell

The right choise for

With the Wera 842/4 hexagon bit, you can smoothly drive 4 mm hexagon socket head screws even when straight-line access to the fastener is blocked. The spherical ball-end profile lets you pivot the tool off-axis, giving you full control when fastening around corners and in awkward angles. Its generous 89 mm length provides extra reach into deep or recessed screw channels, eliminating unnecessary disassembly work. Engineered with tough-viscous steel, the bit tip resists premature breakage during demanding tasks. Featuring a standard 1/4" hexagon drive, it fits seamlessly into conventional bit holders and power tools.

Features and benefits

The spherical drive profile means that it is possible to swivel the axis of the tool to that of the screw, and therefore enable angled, "around-the-corner" screwdriving jobs.
Tough Wera bits prevent the tip from breaking prematurely. Z-bits usually are the bit for universal screwdriving applications.
