Manual impact screwdrivers from Wera, Facom and Gedore

Impact screwdrivers for loosening seized and corroded fasteners

An impact screwdriver converts a hammer blow into a powerful rotational force, breaking free fasteners that resist conventional screwdriver torque. Corroded screws, paint-locked bolts and thread-bound fixings that would strip under steady pressure yield to the sudden, high-torque impulse delivered by a well-aimed strike.

Models with 1/2 inch square drives accept standard socket sets, turning the impact screwdriver into a versatile tool for automotive work, machinery maintenance and industrial assembly. Smaller 1/4 inch and 3/8 inch drive versions handle precision tasks on equipment panels, electronics housings and smaller mechanical assemblies where a full-size driver would be impractical.

Torque output ranges up to 200 Nm, providing enough force to shift even heavily seized fasteners without resorting to heat or penetrating oil alone. The Kraftform Plus handle design on some models improves grip comfort and strike accuracy during repeated use, while compact overall lengths keep the tool manoeuvrable in tight spaces. Impact screwdrivers require no batteries, compressed air or external power, making them reliable standby tools for field service, roadside repairs and workshop situations where powered impact tools are unavailable or excessive for the task.
