The Introduction Of Double End Stud And The Difference Between Single-ended Studs

Double End Studs are threaded fasteners with threads on both ends and an unthreaded portion between the two threaded ends. A stud or stud is a threaded rod threaded on both ends and a smooth shank equal to the nominal diameter; and is designed to be installed in a threaded hole with one threaded end and a hex nut on the other end The device clips onto the surface into which the stud has been screwed into.

Another name sometimes used for studs is Tap End Stud or "fabricated studs". The thread lengths are different at both ends of the tap end stud. It has a short thread for threaded holes and usually has a class 5 mating thread to ensure full engagement.

Note that for metric studs, the short thread is not included in the nominal length of the stud. Studs are used for flange bolting or other applications that require or require spray welding from both ends.

Since studs are threaded on both sides, they can be more easily used to hold two components together, usually with a hex nut (and sometimes a lock nut). During stud tightening, washers can be used to protect the mating surfaces from damage.

These threaded products are very common among gearbox manufacturers and open gears. Other common applications for double-ended studs, tapped single-ended studs and fully threaded studs include wind towers, nuclear power, marine, railway, construction, and various specialty machinery manufacturing. The diversity of these industries requires studs to be made from all types of non-ferrous metals and other specialty materials.
