Frequently Asked Questions
Common questions about Sunmach Duplex Continuous Thread Studs / Stainless Steel Continuous Thread Studs
Specify Stainless Steel Continuous Thread Studs if your main goal is long-term, cost-effective defense against corrosion in outdoor weather, wet marine environments, or standard industrial fluid piping.
Upgrade to duplex continuous thread studs when your piping systems operate under extreme physical weight, massive thermal cycling, or handle highly aggressive chemical media.
Because the advanced metal matrix is twice as strong as traditional steel, engineers can safely specify smaller, lighter diameter studs to hold the same heavy clamping pressure, reducing total fastener assembly weight by up to 60%.
Standard bolts have a sharp line where the smooth shank meets the threads, which acts as a weak spot. Continuous Thread Studs feature an unbroken, all-thread body that eliminates this weak point entirely.
We subject both stud types to rigorous destructive testing, pulling them apart to test weight capacity, shaking them millions of times to verify fatigue resistance, and soaking them in chemical and saltwater baths.
