ISO 3506-1 is the standard for the mechanical properties of corrosion-resistant stainless steel bolts, screws, and studs. To match this to your program, talk with our team.
What ISO 3506-1 Covers
It defines the property grades and tensile requirements for stainless externally threaded fasteners used where corrosion resistance is required.
How the Test Is Run
Stainless bolts and screws are pulled to failure or proof loaded using suitable fixtures, and results are checked against the stainless property grade.
Why It Matters
Verified stainless fastener strength supports safe joints in corrosive service; high-force grips and threaded adapters are essential.
