Product Information

A screwdriver is used for tightening or loosening the screw. A round rod with a flat end, having a handle at the other end, is called a screwdriver. The length of a screwdriver is measured, excluding the handle. The length of a screwdriver varies from 50 millimeters i.e., 2” to 18”.

A combination slotted/hex head cap is often used for self-tapping screws for metal, where the hex head enables greater torque during the initial self-tapping installation, while allowing the convenience of a slotted screwdriver to be used for removal and reinsertion. The purpose of a screwdriver is to both insert and remove screws and nuts. If you want to replace a watch’s battery, you won’t use the same screwdriver you use to hang a shelf on a wall.

Files are sent over to manufacturers containing these models so that there is no miscommunication and all the parts are the same across the board. A flathead screwdriver, also called a slotted screwdriver, is a tool with a wedge-shaped flat tip that is designed to fit into the notch on a slotted screw. These tools can come in various sizes and lengths, including oversized flathead screwdrivers that are useful in automotive work, standard-size screwdrivers for furniture construction, and precision flathead screwdrivers that are suitable for working on computers and other delicate electronics.
