Material/Finish
| SSH-SD-EL-ALK | |
|---|---|
| Main Body | SCM435 Electroless Nickel Plating |
| Nylon Patch | Nylon 11 |
| Strength Class | Thread Part: 10.9 Head ＊1: 5.8 |
＊1： Do not exceed the max. tightening torque. Though strength is increased through heat treatment, the head strength is less than that of thread.
Application
Reducing the size of equipment and devicesScrew return and fallout prevented
Characteristics
- Special low profile screws with small heads and nylon patch.
- The friction of the nylon adhered to the thread suppresses the return rotation of the thread.
- Even if the tightening force is lost, the return rotation is suppressed, preventing the screws from falling off.
- The heat resistant temperature of the nylon patch is 120°C.
- Able to reduce spot facing diameters compared to standard hex socket head cap screws with special low profile.
- All head heights are 1.5 mm or less.
- For space-saving of equipment/devices and applications with limited overhead space.
Usage Example
It is possible to perform spot facing and hide the head in locations where spot facing is not possible with standard hex socket head cap screws with special low profiles.
Precautions for Use
- 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.
