A nutdriver or nut driver is a hand tool for tightening or loosening nuts and bolts. It essentially consists of a socket attached to a shaft and cylindrical handle and is similar in appearance and use to a screwdriver. [1] They generally have a hollow shaft to accommodate a shank onto which a nut is threaded.
For each size bolt or screw and type of head, there is a corresponding size driver prescribed by various ISO standards, including: Internal hex drive: ISO 2936:2014 "Assembly tools for screws and nuts—Hexagon socket screw keys" [5] External hex drive: ISO 4014, 4016, 4017, and 4018 [6]
A hex key (also, hex wrench, Allen key and Allen wrench, Unbrako or Inbus) is a simple driver for bolts or screws that have heads with internal hexagonal recesses ().. Hex keys are formed from a single piece of hard hexagonal steel rod, having blunt ends that fit snugly into similarly shaped screw sockets.
Common sizes include T10, T15, and T25, while T35 and T47 tend to see specialized use. Only the proper driver can drive a specific head size without risk of damaging the driver or screw. The same series of Torx drivers is used to drive SAE, metric and other thread system fasteners, reducing the number of bit sizes required.
This size number is usually stamped onto the shank (shaft) or handle for identification. Each bit size fits a range of screw sizes, more or less well. Each Phillips screwdriver size also has a related shank diameter. The driver has a 57° point and tapered, unsharp (rounded) flutes.
