Screwdrivers, Bits, Keys and Spanners

There are many different types of screw heads. For each of these heads, the right tool is required, with which the screws can be tightened or loosened. Screwdrivers fit only on one type of screw head. Screwdriver systems with bits are flexible in comparison. Depending on the screw head, the appropriate bit is attached to the hand tool. For quick and easy working, bits can be used in cordless screwdrivers. Wrenches in various versions are used to tighten or loosen by hand. Ratchets are special versions, which facilitate the tightening and loosening of screws using the ratchet function. In the field of electronics, screwdrivers and wrenches are used mainly for assembly purposes.
