ISO 898 is the multi-part standard for the mechanical properties of fasteners made of carbon steel and alloy steel. To match this to your program, talk with our team.
What ISO 898 Covers
It sets the property classes and mechanical requirements for bolts, screws, studs, and nuts, with separate parts for externally and internally threaded fasteners.
How the Test Is Run
Fasteners are proof loaded, pulled to failure, or wedge tested using suitable fixtures, and the results are compared against the property-class requirements.
Why It Matters
Property-class verification governs fastener interchangeability and joint safety; high-force grips, wedge fixtures, and threaded adapters are essential.
