Marson 47140 Steel Poly Rivet Nuts 100-Pack

The Marson 47140 is a 100-piece pack of steel poly rivet nuts designed for creating strong, permanent threaded fastening points in thin materials. These threaded inserts provide a reliable solution when working with sheet metal, plastic, fiberglass, or composite materials where traditional welded nuts or tapped holes aren't practical.

Key Features:

• Steel construction for durability and corrosion resistance
• Creates permanent threaded insert in thin materials
• Ideal for automotive, marine, RV, and fabrication applications
• No welding or tapping required for installation
• 100-piece bulk pack for professional and production use
• Compatible with standard rivet nut installation tools

Poly rivet nuts are installed from one side of the material, making them perfect for applications where access to both sides is limited. They expand when the mandrel is pulled, creating a secure mechanical lock that won't spin out under load. These fasteners are commonly used in body panels, brackets, trim mounting, and anywhere a strong threaded connection is needed in thin materials.
