Wera 840/4 IMP DC Impaktor Bits, 4 x 50mm
Wera Impaktor Bits (4 x 50mm) with diamond coating & Hex-Plus tech for high torque, durability & anti-slip performance.
The Wera 840/4 IMP DC Impaktor Bits are high-quality bits designed for hexagonal socket screws, featuring advanced Impaktor technology that delivers an above-average service life even under extreme conditions. The rough diamond-particle coating on the bit tip significantly enhances friction resistance, preventing the bit from slipping out of the screw head and ensuring a secure grip.
Additionally, the Hex-Plus design increases the contact surface within the screw head, minimising the notching effect and virtually eliminating damage to the screw head. These bits are compatible with ¼-inch hexagon holders as per DIN ISO 1173-F 6.3 standards, making them ideal for professional and heavy-duty applications.

- Impaktor Technology: Extended durability under high stress.
