Match the rivet nut thread size to your bolt or screw. For example, if you're using an M5 bolt, select an M5 rivet nut. For imperial fasteners, match the thread designation (e.g., 10-24 or 1/4-20). Grip range — the thickness of the material being fastened — is equally important; generally, measure your sheet metal thickness and choose a rivet nut whose grip range covers that value. As a quick reference: 1/4" ≈ 6.35mm, 3/8" ≈ 9.5mm.

This assortment typically covers a range of common metric sizes (generally M3 through M10) and imperial sizes (generally #8-32 through 3/8-16). See the variant options or contact us for the exact size breakdown and piece count per color/size.

The zinc plating provides moderate corrosion resistance, making these rivet nuts suitable for indoor and semi-protected outdoor applications. For prolonged direct exposure to rain, saltwater, or harsh chemicals, stainless steel rivet nuts are generally recommended. If you're unsure, contact us to discuss the right material for your environment.

You'll need a rivet nut tool (also called a nutsert tool or rivnut tool), available in manual or pneumatic versions. Most standard rivet nut tools are compatible with the metric and imperial thread sizes in this set. Check that your tool's mandrel matches the specific thread size you're installing — mandrels are typically sold separately or included with the tool.

Pull-out and torque-out strength vary by thread size and base material thickness. Larger sizes (e.g., M8, M10, 5/16-18) generally offer significantly higher load capacity than smaller ones (e.g., M3, #8-32). For structural or safety-critical applications, contact us to confirm load specifications before ordering.

Rivet nuts are designed for thin-walled materials where you can only access one side — typically sheet metal, aluminum panels, steel tubing, and rigid plastics. They are commonly used in automotive bodywork, HVAC ductwork, electronics enclosures, and furniture assembly. In most cases, the material thickness should fall within the rivet nut's specified grip range for a secure installation.

Each color corresponds to a specific thread size or size family, making it fast and easy to identify the right fastener without measuring every piece. The color-coded system is especially useful when working with both metric and imperial sizes in the same kit, reducing sorting time and the risk of grabbing the wrong size mid-job.
