Material/Finish

SNS-SD-EL-ALK
Main Body SCM435
Electroless Nickel Plating
Nylon Patch Nylon 11
Strength Class 12.9

Application

Reducing the size of equipment and devices
Screw return and fallout prevented

Characteristics

  • Screws with small heads and nylon patch. Able to reduce the spot facing diameters compared to standard hex socket head cap screws.
  • 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.

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.

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.
