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

The Wera 840/0 Hex Plus Micro Screwdriver Bit in 2.5mm is the largest size in this micro range, making it well suited to slightly larger hex socket screws found in mechanical assemblies, engineering components, and precision equipment. The 30mm length provides practical versatility for a broad range of fastening scenarios. As with all bits in this range, the Hex-Plus profile is the defining feature — by maximising contact between the bit and the screw socket, it virtually eliminates the risk of rounding out the hex recess, ensuring clean, reliable driving even under higher torque demands. Robustly constructed for tough and universal use, this bit is sold individually as a Pack of 1.
