TR TOOLROCK 860pcs Rivet Nut Kit - Complete Metric Assortment

In this review the TR TOOLROCK 860pcs Rivet Nut Kit is evaluated as a practical option for DIYers and light trade use; the single biggest reason to consider it is the large, clearly labeled assortment of metric rivet nuts kept in a configurable transparent box, which makes fast selection easy. The reviewer found the set especially useful when installing threaded inserts into thin sheet materials and appreciates that the kit pairs a durable carbon steel rivet nut tool with a broad range of sizes from M3 up to M12.

Key Features

• 860pcs metric assortment: The kit includes a wide count of rivet nuts (M3 to M12) so you rarely run out of common sizes during projects.
• Clearly labeled storage: All rivet nuts are sorted in a grid with label prompts, which speeds up part selection and reduces hunting time.
• Adjustable transparent box: The storage case is durable, has a transparent lid, and allows grid adjustments to accommodate larger items or loose parts.
• Sturdy carbon steel tool: The included rivet nut tool is heat treated carbon steel, offering strength and corrosion resistance for repeated use.
• Zinc plated finish: The rivet nuts are zinc plated steel, providing extra corrosion protection for long-term fastening in typical workshop environments.
• Included range of sizes: The breakdown covers common metric sizes (M3 x200, M4 x200, M5 x170, M6 x150, M8 x100, M10 x30, M12 x10) to handle many fastening tasks.

Who It's For

This kit is aimed at home mechanics, hobbyists, and small workshop owners who frequently install threaded inserts in sheet metal, automotive panels, or light structural assemblies. The large counts of M3 through M8 sizes make it especially useful for general projects, repairs, and prototype work where a range of thread sizes is convenient.

Those who need heavy industrial production volumes or specialty materials should look elsewhere, as the kit is optimized for general workshop durability rather than high-volume manufacturing or exotic alloy fasteners. Users requiring only a couple of sizes might find smaller, targeted kits more compact.

Pros & Cons

Pros

• Transparent, adjustable storage box with labels makes organization and retrieval straightforward.
• Durable, heat treated carbon steel rivet nut tool and zinc plated nuts offer good strength and corrosion resistance.
