Product Overview

The panel press-in screw has a knurled press-in structure that presses firmly into sheet metal and provides a male thread connection, with a head designed for easy manual turning; it fastens panels, covers and other components that are opened and closed frequently. Once press-fitted, the screw remains captive, so there is no need to hold it while removing or installing a panel, improving maintenance efficiency.

Technical Features

  • Knurled press-in clinching structure stays firmly locked in sheet metal without loosening.
  • The head is easy to turn by hand, so daily maintenance can be tool-free.
  • The screw stays captive during panel service, improving maintenance efficiency.
  • No welding: avoids panel deformation and coating damage
  • The male thread specification can be customised to drawings.
