Metric Thread Sizes and Compatible Plastic Spacers
The inside diameters of our plastic spacers are largely based on the standard clearance hole diameters specified in ISO 273. They are therefore suitable for the following metric screws and thread sizes:
| Inner diameter d1 | Compatible thread |
|---|---|
| 2.2 to 2.6 mm | M2 |
| 2.7 to 3.1 mm | M2.5 |
| 3.2 to 3.6 mm | M3 |
| 4.3 to 4.8 mm | M4 |
| 4.8 to 5.3 mm | M4.5 |
| 5.3 to 5.8 mm | M5 |
Please take advantage of the option to order samples to check the fit with the screws used in advance.
