The Aluminium Flat Head Serrated Nut M4-30 is a self-clinching threaded stud designed for secure fastening in thin metal sheets. Manufactured by PEM®, this nut features a flush head that embeds into the sheet, creating a flush assembly and providing high torque-out and pushout resistances.
Key Features:
- Self-Clinching Design: Installs by placing the nut into a properly sized hole in the sheet and applying pressure, embedding the head into the material for a flush finish.
- High Torque-Out and Pushout Resistances: Provides secure fastening with high resistance to torque and pushout forces.
- Flush Head: Ensures a smooth surface without protrusions, ideal for applications requiring a flush finish.
