Metric Thread Sizes and Compatible Retaining Spacers
The inside diameters of our retaining 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 d | Compatible thread |
|---|---|
| 3.2 to 3.6 mm | M3 |
| 3.7 to 4.2 mm | M3.5 |
| 4.3 to 4.8 mm | M4 |
| 4.8 to 5.3 mm | M4.5 |
| Inner diameter d | Compatible thread |
|---|---|
| 5.3 to 5.8 mm | M5 |
| 6.4 to 7.0 mm | M6 |
| 8.4 to 10.0 mm | M8 |
| 10.5 to 12.0 mm | M10 |
Please take advantage of the option to order samples to check the fit with the screws used in advance.
