"impact screwdriver"的定义和意义

What is an "impact screwdriver"?

An impact screwdriver is a power tool used to drive screws and fasteners into materials, similar to an impact driver, but it is typically smaller and designed specifically for driving screws. It delivers strong bursts of rotational force to make driving screws easier, especially when the material is tough or when a high amount of pressure is needed. Impact screwdrivers are commonly used in construction, automotive, and home improvement projects. They are more efficient than manual screwdrivers and reduce the effort required for tasks that involve driving large or long screws.
