ISO 3506-2 is the standard for the mechanical properties of corrosion-resistant stainless steel nuts. To match this to your program, talk with our team.
What ISO 3506-2 Covers
It defines the property grades and proof-load requirements for stainless internally threaded fasteners.
How the Test Is Run
Stainless nuts are proof loaded on a hardened mandrel or test bolt using suitable fixtures, and the proof performance is checked against the grade.
Why It Matters
Nut proof-load verification ensures stainless nuts carry rated load in corrosive service; hardened mandrels and high-force fixtures are essential.
