Proster 14" Rivet Nut Tool Kit with 6 Metric Mandrels and 150 Rivet Nuts

For workshop jobs that need a threaded fixing on panels, bicycle attachments or furniture, this Proster rivet nut tool provides a hand-operated setting solution. Its 14-inch handles use double compound hinges to maximise leverage. Six interchangeable metric mandrels cover sizes from M3 to M10, and the kit includes 150 rivet nuts for a range of tasks.

Fit and sizing

The six mandrels are sized for M3, M4, M5, M6, M8 and M10 rivet nuts, giving you a range of metric options for different fastening jobs. The supplied nuts are divided across those sizes: 40 M3, 40 M4, 30 M5, 20 M6, 15 M8 and 5 M10. The M5 mandrel is already fitted to the tool, while the other mandrels can be changed to suit the nut size you are using.

The 14-inch tool length and double compound hinge design are useful when a job calls for extra leverage or access to a harder-to-reach spot. For example, when fitting a threaded fixing to a panel, choose the matching mandrel and nut size, then use the hand tool to set it in place. The selection of sizes also makes the kit practical for keeping different fastening options together in a home workshop.

Pros

This is a complete hand-tool kit for setting rivet nuts, rather than a tool supplied on its own: the carrying case stores the gun, interchangeable mandrels and included nuts together, making it easier to organise them between jobs. The 14-inch handles and compound hinges provide the leverage advantage highlighted for this design, while the rubber-coated TPU handles offer a non-slip grip.

The listed applications include body panels, bicycle attachments, furniture and decorations. That makes the kit relevant for repair and assembly tasks where a rivet nut provides a threaded fastening point. Buyer feedback praises the tool’s functionality, including its use on metal sheet panels. Durability feedback is mixed, with some buyers reporting breakage or loose threads at the end of the tool, this is worth bearing in mind when weighing buyer experiences alongside the kit’s specified features.
