Hex Socket Head Cap Screws

Hexagon socket head cap screws (cap bolts)
Bolts with a hexagonal hole on a cylindrical head that's fastened with a hex wrench.
Although they are also called cap screws or socket screws, the most common names are "hexagon socket head cap screw" and "cap bolt". They are generally given black oxide finish.
As only a hex wrench that perfectly fits the size can be used, they can be securely tightened.
For standardized products with long nominal length, half screw and full screw are available.
Mostly used without a nut, with a hex wrench that does not require a large space, they can be used in a narrow space or to help miniaturize a machine.
