Commonly called drywall screw shooters, screw guns offer variable speed settings for different screwdriving applications from hanging drywall to building decks and other projects that require multiple-screw fastening. The higher rpms and lower torque of a screw gun prevents over-tightening and damage to the material or the screw head.
Metal lathe that cuts machine screw threads into a machine screw.
Screw pitch gauge
Gauge that checks the number of screw threads per inch on a screw.
Sheet metal screw that is fully threaded with a tip in the shape of a drill bit and either a Phillips or hex head, which is used to fasten heavy sheet metal. They are zinc-plated and available in various sizes.
Screw thread micrometer

The function of the screwdriver is simple. To drive and withdraw threaded fasteners. Different types of blade tips are used with matching recesses on threaded fasteners. Using the wrong style of screwdriver could damage the tool and/or the fastener. The handle design of better units provides a more comfortable operation with less effort.
Screwdriver bits can be used on both corded and cordless screwdriver or driver/drill units. Screwdriver bits are available for slotted, TORX®, phillips, clutch, robertson (square recess), and hex fasteners.
Expression for using a few screws to hold material in place and then screwing all of the screws simultaneously.
