Colored Zinc Rivet Nut Set — Stop Losing Time Hunting for the Right Thread Size
Mechanics, fabricators, and serious DIYers know the frustration: you're mid-job, you need a threaded insert for thin sheet metal, and you're digging through a pile of identical-looking fasteners trying to find the right size. Whether you're working on automotive panels, HVAC ductwork, or custom enclosures, misidentifying a rivet nut size costs time and can strip threads in material you can't easily replace.
This 600-piece colored zinc rivet nut assortment solves that problem with a color-coded system that lets you identify sizes at a glance. The set covers both metric (generally M3–M10) and imperial (generally #8-32 through 3/8-16) thread sizes, giving you the range to handle mixed-standard projects without switching kits. Each rivet nut is zinc-plated for corrosion resistance and manufactured to standard thread tolerances for reliable bolt engagement. Sizes are available across multiple thread designations — see variant options for the exact count per size.
⚠️ Please Note: This kit includes rivet nuts only. Installation tools (rivet nut tool / nutsert tool) are NOT included and must be purchased separately.
This set is well-suited for automotive body panel repair and restoration, HVAC and sheet metal fabrication requiring blind-side thread inserts, and electronics or equipment enclosure assembly where access is limited to one side of the material. The metric and imperial rivet nut assortment covers the thread sizes most commonly encountered in North American workshops and garages.
Key Features
- Color-Coded by Size — Each thread size is assigned a distinct color, eliminating guesswork when switching between metric and imperial rivet nut sizes on the same job.
- 600-Piece Assortment — A broad selection of thread sizes in a single kit means fewer reorders and more flexibility across automotive, HVAC, and fabrication projects.
- Metric & Imperial Coverage — Includes both metric (generally M3–M10) and imperial (generally #8-32 through 3/8-16) sizes, making this set practical for mixed-standard workshops.
- Zinc-Plated Finish — The zinc coating provides corrosion resistance for indoor and semi-protected environments, extending service life in typical workshop and automotive applications.
- Standard Thread Tolerances — Manufactured to recognized thread standards for consistent bolt engagement, reducing the risk of cross-threading or loose fits in sheet metal rivet nut installations.
- Rivet Nuts Only — Tools Not Included — This kit contains 600 colored zinc rivet nuts only. A rivet nut installation tool (manual or pneumatic) is required and must be sourced separately.

Who Is This For
Frequently Asked Questions
Does this kit include a rivet nut installation tool?
No. This set contains rivet nuts only. A rivet nut tool (also called a nutsert tool or rivnut tool) is required for installation but is not included in this kit. Manual and pneumatic rivet nut tools are widely available and sold separately. Make sure your tool's mandrel is compatible with the thread sizes you plan to install.
How do I choose the right rivet nut size for my project?
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.
What thread sizes are included in this 600-piece set?
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.
Can these rivet nuts be used outdoors or in high-moisture environments?
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.
What type of rivet nut tool is compatible with this set?
Any standard rivet nut tool (manual or pneumatic) with the appropriate mandrel for the thread size you're installing will work. Mandrel sets are typically sold with the tool or available as accessories. Check that your tool supports both metric and imperial mandrels if you plan to use both thread standards from this set. Tools are not included in this kit and must be purchased separately.
How much load can these rivet nuts handle?
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.
What materials can rivet nuts be installed into?
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.
What does the color coding on these rivet nuts indicate?
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.
