Marson 47575 Aluminum Poly Rivet Nuts 5/16-18 Thread (25-Pack)

The Marson 47575 aluminum poly rivet nuts provide a strong, permanent threaded insert solution for thin materials where creating conventional threads would be impractical. These 5/16-18 threaded inserts are ideal for attaching hardware to sheet metal, plastics, composites, and other thin-wall materials commonly found in automotive, marine, RV, and general fabrication applications.

Key Features:

• 5/16-18 thread size for standard bolt compatibility
• Aluminum construction offers excellent strength-to-weight ratio and corrosion resistance
• Poly (polyester) coating provides additional protection against galvanic corrosion
• Installs from one side only—no access to backside required
• Creates strong, reusable threaded connection in materials too thin to tap
• Convenient 25-piece pack for multiple installations

Rivet nuts (also called rivnuts or nutserts) are installed using a special riveting tool that collapses the body from the rear, creating a permanent threaded anchor. Perfect for repair work, custom fabrication, or OEM assembly applications where you need reliable threaded attachment points in sheet metal panels, fiberglass, or plastic components.
