Also you could slip and cause more damage. Etc. According to needs, there are light-duty screwdrivers and heavy-duty screwdrivers. They have a flat tip. Although it can be powered or manually operated, the ‘cam-out effect’ of the slotted head makes power operation less common.Avsafe". www.losspreventionfasteners.com.
