Wera 840/0 4mm Hex Drive Hex Plus Micro Screwdriver Bits

The Wera 840/0 Hex Plus Micro Screwdriver Bit in 0.9mm is one of the smallest sizes in the range, making it perfectly suited to precision and micro fastening tasks where access is tight and screw heads are diminutive. At 30mm in length, it offers a practical reach for delicate work without sacrificing control. Wera's Hex-Plus profile is the standout feature here — by increasing the contact surface area within the screw socket, it significantly reduces the risk of cam-out and rounding, which is especially critical when working with tiny fasteners that are particularly vulnerable to damage. Tough enough for hard materials and built for universal use, this bit is sold individually as a Pack of 1. Features and Benefits: • Hex-Plus profile minimises rounding-out of small, delicate screw heads • Reduced notch effect extends the working life of both bit and screw • Tough construction suitable for hard materials • 4mm hexagonal drive for use with standard bit holders Contents: 840/0 Hex-Plus Micro bit for hexagonal socket head screws, 0.9 x 30mm Specifications: Hex Size: 0.9mm Length: 30mm Drive: 4mm Hexagonal Pack Quantity: 1
