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.

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