Bits for Hex Socket Screws
Product Overview
The 840/1 Z bits from WERA are Z-bits designed for hex (Allen) screws. The 840/1 Z bits are equipped with a 1/4" hexagonal drive and are compatible with Wera connecting series 1. The bit comes with a metric tip size of 6.0 mm and a blade length of 25 mm. The Hex-Plus design provides larger contact surfaces in the screw head, reducing notching and minimizing damage to the screw head.
Function and Construction
The product is a Z-bit with a focus on durability and optimal contact in hex screw heads. The Hex-Plus design means that power transmission occurs from the surfaces instead of the corners in the screw head — a feature indicated by the manufacturer. The bit has a 1/4" hexagonal shank, making it compatible with standard bit holders and Wera's connecting series 1.
