Tap End Stud vs. Double End Stud
Both replace a bolt in repeated assembly, but their ends are threaded differently.
| Feature | Tap End Stud | Double End Stud |
|---|---|---|
| Ends | Short tap end + long nut end | Equal threads both ends |
| Install | Tap end into a tapped hole | One end into a tapped hole or nut |
| Body | Plain middle section | Fully or partially threaded |
| Typical use | Pumps, valves, flanged joints | General studding, anchors |
| Best for | One part stays fixed | Both ends take nuts |
Verdict
A tap end stud threads one end permanently into the part; a double end stud takes a nut on both ends. Match the ends to the joint.
