Advantage:
The eight advantages
for the Schriever STS® geometry
1. Optimum connection of thermoplastics
2. Minimal radial stresses
3. High load capacity
4. Lower thread forming torques
5. Elimination of the risk of relaxation
6. No material damage
7. 8° thread pitch enables optimum self-locking
8. Cost-effective
Application Area:
For joints of thermoplastics in the areas of construction, assembly and load-bearing capacity.
Application Notes:
Vectorial influencesof the main forming direction
Small radial forces - low radial elongation
Our 30° flank angle reduces radial expansion compared to conventional thread flanks with 60° (e.g. self-tapping screws)
A 60° flank angle leads to high surface pressures in screw connections and thus to increased relaxation
