Description
đ ď¸ Wide Series Washer (ISO 7093 / DIN 9021)
You can also choose a thickness different from the standard one
This resource includes the precise 3D model of the Wide Series Flat Washer, conforming to ISO 7093 standard (commonly known as DIN 9021).
Unlike standard washers, the ISO 7093 series features an outer diameter approximately three times larger than the nominal screw diameter. This makes it perfect for:
- Distributing load over soft or thin surfaces (such as 3D printed walls).
- Covering oversized or damaged holes.
- Creating stable support bases on plastic and composite materials.
⨠Technical Details
- Series: Large (Large series).
- Geometry: Optimized ratio between inner hole and outer diameter to prevent the screw head from sinking into the part.
- Compatibility: Designed to perfectly mate with metric fasteners from M3 to M12 (and beyond).
đ Dimensional Table (Large Series)
Dimensions strictly follow ISO specifications to ensure maximum contact area:
| Size (Screw) | Inner Hole (d1) | Outer Diameter (d2) | Thickness (h) |
|---|---|---|---|
| M3 | 3.2 mm | 9.0 mm | 0.8 mm |
| M4 | 4.3 mm | 12.0 mm | 1.0 mm |
| M5 | 5.3 mm | 15.0 mm | 1.2 mm |
| M6 | 6.4 mm | 18.0 mm | 1.6 mm |
| M8 | 8.4 mm | 24.0 mm | 2.0 mm |
| M10 | 10.5 mm | 30.0 mm | 2.5 mm |
đ¨ď¸ Tips for the Maker
- Dimensional Accuracy: Being a mechanical coupling, make sure your flow (Flow Rate) is well calibrated so as not to restrict the central hole.
- First Layer: Given the large outer diameter, ensure excellent bed adhesion to prevent corner warping (especially with ABS or ASA).
- Recommended Material: * PETG or ASA: For better heat resistance and outdoor durability.
- TPU (High hardness): Excellent if you are looking for a washer that also acts as a shock absorber or to seal irregular surfaces.
Pro Tip: If you need a specific dimension not included in the print profile, you can uniformly scale the X and Y model in the slicer, but remember to unlock the Z-axis if you want to maintain the standard ISO thickness!
