HOW-TO
How to generate a hex nut STEP / STL file
- 1Pick the thread size — across-flats s and height m follow ISO 4032.
- 2Choose the thread mode: simplified for assemblies, 3D-print to screw a metal bolt straight into a printed nut.
- 3Check the spec cards and any warnings.
- 4Download STEP, STL or 3MF — or send it to Orinovate for a quote.
What is an ISO 4032 hex nut?
ISO 4032 is the everyday style 1 hex nut, m ≈ 0.8–0.9d high with 30° chamfers on both faces. ISO 4035 is the thin (jam) nut, ISO 4033 the taller style 2. In modeled mode the ISO 68-1 basic internal thread is cut, with minor diameter D1 = d − 1.0825P.
ISO metric thread formulas
The ISO 68-1 basic profile is a 60° triangle with fundamental height H = 0.866P. Pitch diameter d2 = d − 0.6495P, internal minor D1 = d − 1.0825P, external minor d3 = d − 1.2269P, tensile stress area As = π/4 × ((d2 + d3)/2)². For M8 (P = 1.25): d2 = 7.188, D1 = 6.647, d3 = 6.466 mm, As = 36.6 mm². Modeled threads are right-handed and faceted into 36 planar segments per turn (error < 0.4 % of the diameter).

FAQ
What spanner fits an M8 nut, and how tall is it?
ISO 4032 across-flats / height: M3 5.5 / 2.4, M4 7 / 3.2, M5 8 / 4.7, M6 10 / 5.2, M8 13 / 6.8, M10 16 / 8.4, M12 18 / 10.8, M16 24 / 14.8 mm. Across-flats is the spanner size; old DIN 934 / JIS M10 and M12 nuts are 17 and 19 mm.
How big should a printed hex-nut pocket be?
Make the pocket across-flats s + 0.2–0.3 mm (FDM) and depth m + 0.2 mm. An M3 nut (s 5.5, m 2.4) → 5.75 mm across flats, 2.6 mm deep; an M8 nut (s 13) → 13.25 mm. A side-loading slot keeps the nut captive better.
Which nut grade goes with which bolt?
Per ISO 898-2 the nut class should match or exceed the bolt: class 8 nuts for 8.8 bolts, 10 for 10.9, 12 for 12.9. The height m ≈ 0.8–0.9d is chosen so the bolt breaks before the thread strips.
What size hole for an M3 screw? Which tap drill?
Tap drill ≈ nominal diameter − pitch: M3 → 2.5 mm, M4 → 3.3, M5 → 4.2, M6 → 5.0, M8 → 6.8, M10 → 8.5, M12 → 10.2 mm. For a clearance hole (ISO 273): M3 3.2 (fine) / 3.4 (medium), M4 4.3 / 4.5, M5 5.3 / 5.5, M6 6.4 / 6.6, M8 8.4 / 9 mm. The spec cards list both for the selected size.
Do 3D-printed threads work?
Yes, from about M6 up — a 0.4 mm FDM nozzle can barely resolve an M3 thread (0.5 mm pitch). Use the 3D-print mode (external thread shrunk 0.15 mm, internal enlarged 0.2 mm, adjustable), print screws standing up with ≤ 0.12 mm layers. For parts that are assembled often or loaded, heat-set inserts or a captive hex-nut pocket last far longer than printed threads.
Which software opens the hex nut STEP file?
STEP (AP214) opens in Fusion 360, SolidWorks, FreeCAD, Onshape and Rhino. STL / 3MF import directly into Bambu Studio, PrusaSlicer or Cura.

About STEP / STL / 3MF / DXF
- STEP (.step / .stp, AP214) keeps exact dimensions and surfaces for editing in Fusion 360, SolidWorks or FreeCAD.
- STL and 3MF are triangle meshes that import directly into Bambu Studio, PrusaSlicer or Cura.
- DXF is the top-view 2D outline, ready for laser cutting, waterjet or CNC routing.
- All models are in millimetres at true scale.
