The Wera 2090 Impact Driver is a hand-operated impact driver designed to loosen and tighten stubborn fixings without the need for power tools or compressed air equipment. Ideal for tradespeople working in tight spaces or on jobs where a pneumatic impact driver is impractical, the 2090 converts hammer blows into rotary motion directly at the fastener. This makes it particularly effective for breaking free seized or overtightened screws where a conventional screwdriver would simply cam out. The driver features Wera's double-curved body design, which maximises the conversion of impact force into usable torque. Rated at 90 Nm and compatible with M4 to M8 screws, it accepts a 5/16" hexagon socket drive, making it compatible with a wide range of standard bits and accessories.
