Bits for internal hexagon bolts — 840/1 Z bits
840/1 Z bits from WERA are bits designed for screwing internal hexagon bolts. The product is listed under WERA's 840/1 Z bits product series and is described as a robust Z-bit with a Hex-Plus profile.What the product is and how it works
840/1 Z bits utilize the Hex-Plus profile, which increases the contact surface with the screw's flats rather than just working in the corners. This reduces the risk of notching in the screw's internal hexagon. The bit has a 1/4" hexagon drive, suitable for holders according to DIN ISO 1173‑D 6.3. On the WERA website, the specific variant with manufacturer's part number 05135060001 is indicated with a tip diameter of 0.05" and a blade length of 25 mm.- Profile: Hex-Plus (larger contact surfaces in the screw's recess)
