Bolt
Cylindrical bar with square or hexagonal head, threaded at one end to receive a nut.
The threaded section does not continue as far as the head. A bolt is a commonly used fixing for joining metal parts.
Note 1: The French term boulon is also used for the combination of a nut and bolt.
Note 2: The term set screw and the French term vis calante are used when the threaded part continues as far as the head.
Note 3: The term stud applies to a set screw without a head.
Please note that this is the term as it stands in the original IALA Dictionary edition (1970-1989)
