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

The Wera 840/0 Hex Plus Micro Screwdriver Bits are precision-engineered bits designed specifically for hexagonal socket head screws. Featuring Wera's innovative Hex-Plus profile, these bits offer significantly larger contact surfaces within the screw head compared to standard hex bits, dramatically reducing the notch effect and virtually eliminating the risk of rounding out or destroying the screw head.

Constructed to be tough and resilient, these bits are suitable for universal use across a wide range of materials, including harder substrates where lesser bits would fail. The 4mm hexagonal drive shank ensures compatibility with standard bit holders and screwdrivers.

Available in hex sizes from 0.9mm to 2.5mm, all at a 30mm length, making them ideal for precision and micro fastening applications.

• Hex-Plus profile provides larger contact surfaces, reducing screw head damage
• Notch effect reduced to a minimum for longer bit and screw life
• Tough construction suitable for hard materials and universal use
