These nuts are pressed into a pre-punched hole in the host material using a press tool.
The material around the hole is displaced into a recess in the nut, creating a secure and permanent attachment.
Installation typically requires only a press, eliminating the need for additional hardware or welding.
The shank or pilot of the nut has an annular recess where the displaced material flows, locking the nut in place.
Many self-clinch nuts have knurled or ribbed features that further enhance the mechanical lock by increasing friction.
Materials
Steel: Common for general applications due to its strength and durability.
Stainless Steel: Provides excellent corrosion resistance, suitable for harsh environments.
Aluminum: Lightweight and corrosion-resistant, ideal for applications where weight is a concern.
Types
Self-Clinching Nuts (Standard): Basic nuts for general applications.
Self-Clinching Studs: Similar to nuts but with a threaded stud instead of a threaded hole.
Self-Clinching Standoffs: Provide a threaded hole with a specific stand-off distance, useful in electronics for mounting circuit boards.
Applications
Sheet Metal Fabrication: Widely used in automotive, aerospace, and electronics industries where components are mounted to thin sheet metal.
Enclosures: Ideal for attaching panels and covers in electrical enclosures.
Electronic Assemblies: Used for mounting circuit boards and other components securely.
Automotive: Common in various applications within vehicles, providing secure attachment points without welding.
