An impact screwdriver is a specialized hand tool designed to loosen or tighten stubborn screws, bolts, or fasteners with minimal effort. It features a unique mechanism that delivers high torque impulses to the screwdriver bit upon striking it with a hammer or mallet. This sudden impact helps break loose rusted or seized fasteners that would otherwise be challenging to remove with conventional screwdrivers. Impact screwdrivers are commonly used in automotive repair, machinery maintenance, and construction projects where stubborn or corroded fasteners are prevalent. They offer increased leverage and power compared to traditional hand tools, making them indispensable for tasks requiring extra force and precision. With their simple yet effective design, impact screwdrivers save time and effort while ensuring secure and efficient fastening solutions.
