HARDELL 14-Inch Rivet Nut Tool Kit with 80 Rivet Nuts and 6 Mandrels

For fastening jobs that call for threaded inserts in sheet material or panels, this hand rivet nut tool kit brings the tool and a selection of rivet nuts together in one case.

Six interchangeable mandrels cover metric and inch thread sizes, so you can select the size that matches the insert for the job.

A curved, soft-rubber handle and force-control arm support a smooth, controlled squeeze. The quick-change head lets you swap mandrels without a tool, helping keep setup straightforward when moving between sizes.

Tips for day-to-day use

Choose a rivet nut and mandrel with matching thread size before starting. The kit covers M6, M8, M10, 1/4-20, 5/16-18 and 3/8-16, giving you options for a range of fastening tasks. A colour-coded mandrel and storage system helps identify the size at a glance, particularly when you are switching between inserts during a project.

For a home repair or workshop task, keep the tool and the included rivet nuts together in the carrying case, then select the matching size for the panel or assembly. The hand-operated design suits work where a rivet nut is the preferred fastening method and a compact, portable kit is useful. Follow the installation steps for the selected rivet nut to set it correctly.

What stands out

The set combines the hand tool, six mandrel sizes and 80 rivet nuts, rather than requiring you to assemble a tool and inserts separately. That makes it practical for projects that use more than one thread size and gives you a selection of inserts ready to organize in the rugged carrying case. The case also keeps the kit together between jobs.

The curved soft-rubber grip and force-control arm are designed to make each squeeze smooth and controlled. When a project calls for a different insert size, the quick-change head supports tool-free mandrel changes, while the colour coding helps you find the corresponding size quickly. Buyers often praise the tool’s ease of use and functionality, feedback on construction and durability is mixed, so perceptions of those aspects vary.
