The Penn Engineering 1464-5A is a self-clinching fastener designed for permanent installation in sheet metal and electronics assemblies where load-bearing threads and reliable long-term performance are essential. This fastener delivers secure, durable fastening across demanding environments including automotive electronics, aerospace, and consumer electronics applications.
Technical Specifications
Fastener Type: Self-clinching fastener (nuts, studs, standoffs, or specialized fastening components)
Material Options: Steel (zinc-plated), stainless steel, or aluminum alloys. Specialty materials including Nickel Aluminum Bronze (AMS 4640, UNS C63000) available for enhanced corrosion resistance and strength.
Surface Finishes: Standard zinc plating with clear trivalent coating. Copper flash and dry film lubricant finishes available. Custom finishes offered to meet corrosion resistance and anti-galling requirements.
Installation Method: Installed via standard press operation—fastener is placed in a properly sized hole and squeezed into position, permanently expanding the back-end to form a clinch.
– Key Features
