Wera 840/4 IMP DC Impaktor Bits, 4 x 50mm

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.

Key Features:

• Impaktor Technology: Extended durability under high stress.
• Diamond-Particle Coating: Prevents slippage for safer, more efficient work.
• Hex-Plus Design: Reduces wear on screw heads and ensures reliable torque transfer.
• Compatible with Standard Holders: Fits ¼-inch hexagon drivers as per DIN ISO 1173-F 6.3.

Whether you're handling automotive repairs, industrial assembly, or heavy-duty construction work, these Wera Impaktor Bits provide unmatched performance and longevity.
