Nut driver

A nutdriver or nut driver is a <a href="/facts/Hand_tool/RSzN3Voa">hand tool</a> for tightening or loosening <a href="/facts/Nut_(hardware)/RvmcvYH8">nuts</a> and <a href="/facts/Screw/Rr0k38TC">bolts</a>. It essentially consists of a <a href="/facts/Socket_wrench/wHPSmjdc">socket</a> attached to a shaft and cylindrical handle and is similar in appearance and use to a <a href="/facts/Screwdriver/vJrJRlPz">screwdriver</a>. They generally have a hollow shaft to accommodate a shank onto which a nut is threaded. They are typically used for lower <a href="/facts/Torque/KcrcvNtV">torque</a> applications than <a href="/facts/Wrench/DWaIh3DW">wrenches</a> or <a href="/facts/Socket_wrench/wHPSmjdc">ratchets</a> and are frequently used in the appliance repair and <a href="/facts/Electronics/E4JhgISq">electronics</a> industries.
Variations include T-shaped handles for providing the operator with a better grip, <a href="/facts/Ratchet_(device)/aCNyaXw5">ratcheting</a> handles, sockets with recessed magnets for holding <a href="/facts/Fastener/earBwoS6">fasteners</a>, and flex shafts for bending around obstructions.
Indexable bits with the same purpose, to be held either in indexable handles or in power tool chucks, are called nutsetters.
A spinner handle is a shaft and handle with a drive fitting—most commonly 1⁄4 in (6.35 mm) square axle at the end for attaching interchangeable sockets. This allows one to use a single handle with a number of sizes instead of having a separate nut driver for each size. However, a spinner lacks the benefit of a hollow shaft; thus, a common alternative system is a single handle with interchangeable shafts in each size.
