Precautions for Use
- Screw hole inner diameter on the cover side shall be at least the dc dimension.
- The cover thickness should be 0.8 mm or above.
- Since the head bearing surface area is small, the bearing surface pressure increases.
- Using the following formula as a reference, ensure that the bearing surface pressure due to screw tightening does not exceed the permitted surface pressure of the intended fastening material.
Head Diameter and Screw Effective Cross-Sectional Area
| Part Number | Head Diameter (mm) | Screw Effective Cross-Sectional Area (mm2) |
|---|---|---|
| SSC-M3-SD | 4.5 | 5.03 |
| SSC-M4-SD | 5.5 | 8.78 |
| SSC-M5-SD | 7 | 14.2 |

Installation Example
Make a screw hole in the cover, and then pass the SSC-SD thread part through it. Even when the screw is removed from the frame, SSC-SD does not fall out of the cover because the SSC-SD thread part catches on the cover screw hole.
