another object, normally not using a nut (see bolts compared with screws). The most
common examples are securing a pulley or gear to a shaft. Set screws are usually
headless (also called blind), meaning that the screw is fully threaded and has no head
projecting past the major diameter of the screw thread. If a set screw has a head, the
thread will extend all the way to the head (whereas a bolt might have an unthreaded
shank between the head and thread). A blind set screw (known in the UK as a grub
screw, quite possibly from its figurative resemblance to a soil-dwelling grub) is almost
always driven with an internal-wrenching drive, such as a hex socket (Allen), star (Torx),
square socket (Robertson), or slot. The set screw passes through a threaded hole in the
outer object and is tightened against the inner object to prevent it from moving relative
to the outer object. It exerts compressional or clamping force through the bottom tip
that projects through the hole.
