Astro Pneumatic Tool RN5M M5 5mm Steel Rivet Nuts-100 Piece

The Astro PN5M rivet nut pack includes 100 zinc-plated steel rivet nuts designed for sheet metal fastening. Each nut features a M5 × 0.8 threaded insert. Its outer diameter measures 6.9 mm, and the correct drill-hole size is 7 mm (9/32 in). The nuts are 13.1 mm long and offer a grip range suitable for sheet metal thickness between 26 and 16 gauge.

These rivet nuts provide a strong, threaded anchor point in thin or unreinforced sheet metal — something welding or standard nuts cannot reliably achieve. Because they install from one side, you don’t need access behind the panel. That makes them perfect for automotive bodywork, repair panels, custom metal brackets, trailers, or any thin-metal project.

Installation is straightforward if you use a compatible rivet-nut setter (manual or pneumatic). After drilling the correct hole, you insert the rivet nut and use the setting tool. The nut deforms and expands behind the sheet metal to lock securely in place. Once set, you get a flush base with a properly threaded M5 insert. 

The steel body ensures durability and load capacity. Zinc plating resists corrosion, which is important when used on vehicle bodies or outdoor metal components. These rivet nuts suit applications like mounting brackets, attaching fillers, installing guards, or fixing panels and trim.

Because the pack includes 100 nuts, you have ample stock for multiple projects. This makes it cost-effective for workshops, custom builds, or restorations. Multiple nuts also allow for replacements or repeated use on different jobs.

In short: Astro RN5M rivet nuts deliver reliable threaded fastenings in thin sheet metal. They make metalwork simpler, faster, and more robust — especially where weld-nuts or welds aren’t practical.
