| Manufacturing Specification |
ASTM F468 (Standard Specification for Nonferrous Bolts, Hex Cap Screws, Socket Head Cap Screws, and Studs for General Use). Dimensional tolerances strictly follow DIN 975 / DIN 976 and ASME B18.31.2 for continuous threading. Material conforms to ASTM B164. |
| Thread |
Metric ISO standard. Available as Fully Threaded (Continuous Thread), Double End Studs, and Tap End Studs. Class 6g tolerance for metric threads. |
| Properties & Applications |
Crucial for secure flanged connections in marine engineering and offshore oil & gas platforms. Monel 400 stud bolts provide high strength and outstanding resistance to flowing seawater, brine, hydrofluoric acid, and sulfuric acid. They offer excellent toughness over a wide temperature range, making them ideal for subsea and chemical processing applications. |
| Marking |
In accordance with ASTM F468. Standard markings for continuous thread studs are typically applied to the end faces, including Manufacturer Identification (Ananka) and the respective Grade identifier. |
| Qualification & Acceptance |
Independently tested for thread tolerance, hardness, chemical analysis, and supplied with EN 10204 Type 3.1 Material Test Certification. |
