🔩 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

- 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.
