Product Overview
The Wera 840/4 Z (05059605001) is a screwdriver bit designed for internal hexagon screws. The product is from WERA and is identified by the manufacturer's part number 05059605001. The bit has a 3.0 mm hexagon profile and a 1/4" hexagon drive (Wera Series 4) with an overall length of 50 mm.
Features and Design
- Hex-Plus profile, which provides larger contact surfaces between the bit and the screw to reduce the rounding of screw heads.
- "Z" designation: extra-hard and impact-resistant bit type, indicated by the manufacturer for universal use and to reduce the risk of tip breakage.
- 1/4" hexagon drive (Wera Series 4), which makes the bit compatible with standard 1/4" bit holders and handles.
Function and Application
The Wera 840/4 Z (05059605001) functions as a replaceable bit for wrench or driver tools with a 1/4" drive. The bit is used for installing and removing screws with an internal hexagon (Allen) where a 3.0 mm profile is required. The Hex-Plus profile's larger contact surfaces reduce mechanical wear on screw heads, and the Z-type is designed for increased rigidity to reduce tip breakage under load.
