HARDELL 16-Inch Auto-Release Rivet Nut Tool Kit with 13 Mandrels and 186 Nuts
Product description
For fastening metal plates or taking on repairs around a vehicle, furniture or doors, this kit brings a range of rivet nut sizes together with the tool. Its 16-inch handle is shaped for a comfortable grip during extended work. The auto-release action helps keep installation moving, while the carrying case keeps the mandrels and nuts organized between jobs.
Fit and sizing
The 13 interchangeable mandrels cover metric sizes M3, M4, M5, M6, M8, M10 and M12, along with SAE sizes 8-32, 10-24, 1/4-20, 5/16-18, 3/8-16 and 1/2-13. That range makes it practical to keep one kit on hand for projects using different threaded fastener sizes, rather than selecting a tool around just one size. Match the mandrel and rivet nut to the fastening requirement for the job. When working with smaller mandrels, use care not to apply excessive force, which can cause jamming.
Where it shines
Use the HARDELL tool for tasks such as fastening metal plates and repairing or assembling cars, bicycles, doors, windows, furniture and shelves. The long handle is designed to reduce effort during use, and the ergonomic shape supports a more comfortable grip over a series of installations. Once a rivet nut is set, the automatic retraction releases it with an up-and-down handle motion, so there is no need to manually loosen the nut. A quick-change head also lets you swap mandrels without extra tools, which is useful when a project calls for more than one size.
For a repair that moves between different fastener sizes, the set’s metric and SAE options offer a more ready-to-use approach than buying around a single mandrel. The 186 rivet nuts and durable carrying case add practical organization: the mandrels are stored in separate plastic boxes, and the case keeps the kit together for transport or storage. Buyers commonly praise the tool’s ease of use and functionality. Feedback is mixed on construction, durability and spare-part availability, so the documented strengths are its range of sizes, quick changes and automatic release.
