What type of fastener is threaded from end to end with no head?

A fastener that is threaded from end to end without a head is classified as a stud. Studs are typically used in construction and machinery to provide a strong and reliable connection between two components. They are designed to be inserted into a threaded hole in one component, with the other component then fastened onto the exposed threads. This configuration allows for greater versatility in assembly and disassembly, as the stud remains fixed while components can be easily removed or replaced.

In contrast, other types of fasteners have distinct characteristics that differentiate them from studs. For instance, an anchor is used to secure objects to a structure and is not fully threaded. Bolts possess a head, making them suitable for fastening two parts together with the head serving to keep it in place. Nuts are also fasteners that require a mating part with external threads for fastening, functioning specifically as an internally threaded counterpart to bolts or studs, rather than existing as unheaded threaded elements.
