Studs
What are Studs?
Studs are long threaded rods or shafts with threads on both ends or continuously along the entire length. Unlike bolts, studs do not have a head and are used where high-strength clamping is required between heavy components, such as engines, piping, or structural parts. Studs are ideal for precise torque applications, often paired with nuts on both ends.
Key Features
- Threaded Both Ends or Full Length – Offers strong and balanced clamping force.
- High Load Capacity – Suitable for heavy mechanical assemblies.
- Custom Lengths Available – Cut-to-size based on application.
- Multiple Grades – Available in low carbon, alloy steel, and stainless steel.
- Used in High-Temperature, High-Pressure Systems
Types of Studs
- Fully Threaded Studs
- Double-End Studs
- Tap-End Studs
- Continuous Thread Studs
- Weld Studs

Do you have questions?
When should I use a stud instead of a bolt?
Studs are ideal for high-strength, permanent or semi-permanent joints requiring torque balance and load distribution.
Can studs be supplied in custom lengths or grades?
Yes, we manufacture cut-to-length studs in various grades and finishes for specific project needs.
What are double-end studs used for?
Double-end studs are typically used in engine blocks, turbines, or flange assemblies where nuts are applied on both ends.
Do you offer traceability for critical-use studs?
Yes. All studs can be delivered with material test certificates and third-party inspections.
