Screw Clearance Test
Description
PDFAvailable Variants
Nominal Thread Diameters
There are eight different thread sizes available based on the ISO standard for metric threads. (Naming convention: M<diameter in mm>, here the pitch im mm is given in brackets)
- M4 (0,7)
- M6 (1)
- M8 (1,25)
- M10 (1,5)
- M16 (2)
- M20 (2,5)
- M24 (3)
- M30 (3,5)
Screw Lengths
For each thread diameter there are four lengths of screws provided. (Naming convention: M<nominal diameter in mm>L<screw length in mm>, if there is no length given then the length of the screw is equal to the nominal diameter)
Clearances (Nuts)
For each thread diameter there are hex nuts with four levels of clearance provided. The amount of clearance is indicated by the number of dimples along the nut's perimeter. (Naming Convention: M<nominal diameter in mm><clearance level>)
Clearance for Thread Diameters up to M8
| Clearance Level | Number of Dimples | Clearance in mm | Thread Profile Offset in mm |
| <none> | 2 | 0,05 | 0,1 |
| C2 | 3 | 0,10 | 0,2 |
| C3 | 4 | 0,15 | 0,3 |
| C4 | 5 | 0,2 | 0,4 |
Clearance for Thread Diameters above M8
| Clearance Level | Number of Dimples | Clearance in mm | Thread Profile Offset in mm |
| <none> | 2 | 0,05 | 0,1 |
| C2 | 3 | 0,10 | 0,2 |
| C3 | 4 | 0,20 | 0,4 |
| C4 | 5 | 0,30 | 0,6 |
The clearance is achieved by moving the thread profile the corresponding offset radially outward.
Printing Instructions
- Material: PLA
- Brim: recommended for smaller parts
- Supports: none
- Sequential printing: recommended (for Prusa-Slicer see: Sequential printing | Prusa Knowledge Base (prusa3d.com))
For smaller thread sizes, smaller layer height recommended.
