The principle

Thread-forming screws are connecting elements that form their own internal thread when being screwed into core holes drilled in ductile metals.

The trilobular geometry

The trilobular (triangular) geometry of the screw shaft for the past three decades has proven its worth for non-cutting thread forming of internal threads.

Advantages

Easy positioning Low thread forming momentHigh vibration resistanceNon-cutting thread forming••••
