Note: Fully threaded rods (continuous thread) are heavily utilized in ASME B16.5 flange connections. The 8UN thread series is typically used for nominal diameters 1 inch and larger to ensure greater stress area and superior vibration resistance.

Important: For DIN 938, the tap-end engagement length is approximately 1×d. When ordering metric double-end studs, the nominal length (L) specifically excludes the metal tap end (b1). Contact Ananka Group for DIN 939 standard studs (engagement length 1.25×d).
■ Stud-Specific Technical Specifications
| Material |
Inconel 600 (Nickel-Chromium-Iron Solid-Solution Alloy) |
| Manufacturing Standards |
- ASTM F2281 (Spec for High Temp/Heat Resistance Studs)
- ASME B18.31.2 (Continuous Thread Studs)
- DIN 938 & DIN 939 (Double-End Studs)
|
| Engineering Advantages over Bolts |
Utilizing studs allows for more precise tensioning (via hydraulic tensioners), better distribution of clamp loads across flanges, and entirely eliminates the torsional stress introduced into a fastener's shank when rotating a bolt head. |
| Thermal Limits |
Endures continuous exposure up to 1800°F (982°C) without losing structural integrity. Total immunity to chloride-ion stress-corrosion cracking (SCC). |
| Primary Applications |
Heavy petrochemical assemblies, offshore platforms, pressure vessels, nuclear reactor internals, and high-temperature ASME B16.5 pipe flange connections. |
