Quick answer
What is a threaded stud?
A stud is a headless fastener threaded along its full length or at both ends. It is either screwed into a tapped hole with a nut on the free end, or used with a nut on each end — the common arrangement for bolting pipe flanges together.

Key takeaways
- Studs have no head; nuts provide the clamping on one or both ends.
- Fully threaded studs are standard for flange bolting.
- Diameter, pitch, length and material define each size.
- Nuts and washers are usually specified as part of the set.
How Studs Work in Practice
Studs are preferred wherever a joint is opened repeatedly or a bolt head would be impractical. On flanges, a fully threaded stud with two nuts lets the joint be tightened from either side; on equipment, a double-end stud fixed into a tapped casting protects the parent thread during maintenance.
Because studs often sit in pressure, temperature or structural joints, their material and dimensions should follow the governing drawing or specification. List each size with quantities, and state any nut, washer or coating requirement.
Common Stud Forms
Double-end stud
Threaded at both ends with a plain centre; one end often screws into a tapped hole.
Stud bolt with nuts
Supplied as a set with two nuts per stud for ready installation.
Cut-length threaded rod
Threaded bar cut to required lengths for supports and anchoring.
How to Choose the Right Stud
01
Length for the Joint
Length should cover both flanges, gasket, nuts and the required thread protrusion beyond each nut.
02
Material Specification
Pressure, temperature and corrosion conditions decide the material; follow the project specification.
03
Thread Form
Confirm metric or inch threads and coarse or fine pitch to match nuts and tapped holes.
04
Coating & Exposure
Outdoor and process service may call for a protective coating to keep nuts free for removal.
Stud vs Bolt
Both clamp a joint; the difference is where the tightening happens and how the joint is maintained.
| Criteria | Stud | Bolt |
|---|---|---|
| Head | No head | Integral head |
| Tightening | Nut on one or both ends | Head and nut, or into a tapped hole |
| Typical use | Flanges, casings, frequently opened joints | General assembly and fabrication |
| Thread protection | Protects tapped holes in castings | Repeated removal wears tapped holes |
