Square Nut STEP Files
Square nuts to DIN 557, M6–M12. The square body locks against channel and frame slots to resist rotation — checking fit against slot width is the main use.
Free 3D CAD models (STEP AP214). Built to real standard dimensions; threads are simplified (plain shank) per free-library convention.
Standard: DIN 557

Using these STEP files in CAD
- STEP AP214 format opens directly in SolidWorks, Inventor, Fusion, CATIA, NX, FreeCAD, and most CAD systems.
- Per free-library convention, threads are not modeled (plain shank). These are for layout, clearance, and drawings — not fastening simulation.
- All dimensions use the standard's nominal values. For tolerance-critical use, check the allowances in the spec table.
