STANDARD DATABASE
-
Huge standard data base contains extensive list of parameters for many used materials and geometries for engineering design. Thus it is also a big compendium of materials.
-
Extensible with own definitions
Geometrical definitions:
- 213 thread dimensions (M1 to M100x2 fine thread) in 6 tolerances teach for inner and outer thread
- various screw geometries (drives, bearing surfaces etc.)
- Material definitions:55 screw materials (incl. steel, stainless steal, aluminum, titanium, copper etc.)
- 137 materials for clamped parts and nut thread components
