Expanding Rivet Nut
An expanding rivet nut is a specialized fastener designed to provide strong, reliable threads in thin or soft materials such as sheet metal, plastic, and composites. Unlike standard rivet nuts, the expanding rivet nut features a slotted body that expands during installation, creating a large backside footprint for superior grip and pull-out resistance. This makes it ideal for applications where standard fasteners may not hold securely.
With easy installation from one side of the workpiece, it’s perfect for blind or restricted-access areas. Choose our expanding rivet nuts for enhanced strength, versatility, and convenience!
Material Options: Available in steel, stainless steel, and aluminum to suit various strength and corrosion resistance requirements.
Thread Sizes: Offered in both metric (M4 to M10) and imperial (6-32 to 3/8-16) sizes for diverse application needs.
Body Design: Slotted and collapsible body structure that expands behind the panel during installation, creating a wide load-bearing surface.
Head Styles: Available in flat head, countersunk head, and reduced head options for different surface finishes.
Grip Range: Designed for use in a wide range of material thicknesses, especially effective in thin or soft materials.
Finish Options: Zinc plated, passivated, or anodized for improved corrosion resistance and aesthetics.
Thin Sheet Metal Assembly: Ideal for adding strong threaded connections in thin steel or aluminum panels without welding or tapping.
Plastic and Composite Materials: Excellent performance in soft or brittle materials where traditional rivet nuts may not grip securely.
Automotive Industry: Commonly used in body panels, bumpers, and interior components where blind-side access is required.
Furniture Manufacturing: Provides strong threads in particle board, MDF, or plastic furniture components for easy screw installation.
HVAC and Electrical Enclosures: Used to fasten components inside metal cabinets or control panels with limited rear access.
Construction and Building Fixtures: Suitable for securing metal brackets, signage, and cladding panels to hollow or inaccessible structures.
What is an expanding rivet nut?
An expanding rivet nut is a type of threaded fastener designed to create a strong anchor point in thin or soft materials. It expands behind the panel during installation to form a secure hold.
How does an expanding rivet nut work?
When installed with a rivet nut tool, the body of the nut collapses or expands behind the base material, locking it into place even in oversized or irregular holes.
Are expanding rivet nuts reusable?
The nut itself stays in the base material permanently, but the internal threads allow bolts or screws to be inserted and removed repeatedly.
What sizes are available?
Expanding rivet nuts come in a range of metric and imperial sizes to suit different hole diameters and grip ranges. Refer to the manufacturer’s specifications for exact dimensions.
