DIN 969 is the standard describing conditions for the axial-load fatigue testing of threaded fasteners and the evaluation of results. To match this to your program, talk with our team.
What DIN 969 Covers
It defines the setup and result evaluation for high-cycle axial fatigue of bolts and studs, used to compare designs, materials, coatings, or production lots.
How the Test Is Run
A fastener is cycled under a defined fluctuating axial load until failure or run-out, and the fatigue behaviour is evaluated under the defined conditions.
Why It Matters
Fatigue verification protects against cyclic-load failure of critical bolts; a fatigue-rated axial machine and precise alignment are essential.
