Wera 840/1 Impaktor Hexagon Screwdriver Bits

The Wera 840/1 Impaktor Hexagon Screwdriver Bits are premium-quality bits engineered specifically for hexagonal socket head screws, designed to excel even under the most demanding conditions. Built around Wera's innovative Impaktor technology, these bits deliver an above-average service life, making them the ideal choice for professionals who rely on impact drivers day in, day out.

The rough diamond-particle coating on the bit tip dramatically enhances friction resistance, literally biting into the screw head to prevent cam-out and slipping. Combined with Wera's Hex-Plus profile, which maximises the contact surface within the screw head, the notching effect is reduced to a minimum — protecting both the bit and the fastener from damage.

Available in hex sizes from 4mm to 6mm and lengths of 25mm or 50mm, with pack sizes of 5 or 10 pieces to suit your needs.
