🔩 M8 Bolts Set (Hex & Socket) – High-Strength 3D Printable Screws

This model provides a complete set of M8 bolts in multiple lengths, designed for strong and reliable 3D printing. Perfect for functional prototypes, fixtures, and non-critical mechanical applications.

📏 Included Sizes

All bolts are M8 (8 mm nominal diameter, 1.25 mm pitch) and come in the following lengths:

10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 125, 150 mm

🔧 Design Features

  • Standard M8 thread (1.25 mm pitch)
  • Available with:
    • Hex head (SW13)
    • Socket head (6 mm hex key / Allen)
  • Optimized tolerances for typical FDM printers
  • Clean chamfers for easier threading

🖨️ Print Settings (Recommended)

For maximum strength and durability:

  • Layer Height: 0.12 mm
  • Infill: 100%
  • Material: PETG, ABS, or Nylon recommended (PLA possible but less durable)

⚠️ Notes

  • These bolts are intended for light to moderate mechanical use.
  • Not suitable for high-load, safety-critical, or structural applications.
  • Slight post-processing (thread cleanup) may improve fit depending on printer calibration.

🧠 Tips

  • Use a real M8 nut to “tap” the thread after printing for smoother operation.
  • If threads feel tight, scale the model slightly (e.g. 100.5–101%).
  • For best results, ensure good cooling and precise extrusion.

📦 Use Cases

  • Prototyping
  • DIY projects
  • Jigs & fixtures
  • Replacement parts (temporary)

Enjoy printing! 🚀
If you need other sizes, threads, or custom tolerances, feel free to modify the model.
