ISO 898-1 is the standard for the mechanical properties of bolts, screws, and studs made of carbon steel and alloy steel. To match this to your program, talk with our team.
What ISO 898-1 Covers
It defines the property classes and the tensile, proof-load, wedge, and hardness requirements for externally threaded steel fasteners.
How the Test Is Run
Bolts and screws are proof loaded, pulled to failure, and wedge tested using suitable fixtures, and results are checked against the property class.
Why It Matters
Property-class verification underpins bolted-joint safety and interchangeability; high-force grips, wedge fixtures, and threaded adapters are essential.
