Astro Tools Rivet Nut Setters: Professional Fastening for Every Application

When it comes to reliable, professional-grade rivet nut tooling, Astro Pneumatic Tool has built a well-earned reputation among auto technicians, fabricators, and serious DIYers. Their rivet nut lineup covers the full spectrum of fastening needs — from compact hand tools for tight quarters to high-powered pneumatic setters for production-level work — all engineered with the kind of thoughtful design details that make a difference on the job.

A Full Range of Rivet Nut Setting Tools

Astro's rivet nut catalog spans six focused products, each targeting a specific use case. At the core of the lineup is the iconic Model 1442 — a 13-inch hand riveter kit that has become a go-to in professional shops. It features a shorter handle with double compound hinges that maximize leverage, and a unique spring-loaded inner hex sleeve that automatically locks the rotation of hand-installed mandrels — meaning disassembly of the tool is never required. The kit includes 6 interchangeable mandrel/nosepiece sets and rivet nuts in Metric M5, M6, and M8, as well as SAE 10-24, 1/4-20, and 5/16-18.

For work in tighter spaces, the Model 1443B pistol-style setter brings serious power in a smaller package. At only 7.5 inches long, it fits where most 1/4-inch capacity tools do not, and includes a rivet nut assortment in sizes M4, M5, M6, 8-32, 10-24, and 1/4-20.

Astro also addresses specialty fastening scenarios with their PlusNut and Extra-Long Rivet Nut Setter Kit. This tool is adapted for PlusNut and long rivet nut use and includes extra-long mandrels covering 10-32, 10-24, 1/4-20, 5/16-18, 3/8-16, M5 x 0.8, M6 x 1, M8 x 1.25, and M10 x 1.5 — along with a quick-change 13-inch rivet nut setter and storage case.

Pneumatic and Drill Adapter Options

For high-volume or production work, Astro offers the PRN1 Pneumatic Rivet Nut Setting Kit. It lets you instantly set rivet nuts with the pull of the trigger and quickly un-thread set rivet nuts by operating a free-spinning rear wheel, with a traction power of 2,680 lbs and work capacity up to 3/8-inch (M10) in aluminum and steel nuts. The lineup also includes the ONYX series of pneumatic rivet nut setting guns, available in multiple mandrel configurations for even greater versatility.

Astro's innovative Rivet Nut Drill Adapter Kit rounds out the range for shops that prefer battery-powered tools. The tool is machined from a single CNC-machined piece of billet aluminum and features Japanese bearings and Cro-Mo mandrels, easily converting cordless or corded drills into power rivet nut setters.

Why Choose Astro Tools for Rivet Nuts?

What sets Astro apart in the rivet nut space is the consistency of their engineering across tool types. Whether you're working with a hand setter or a pneumatic gun, you'll find dual SAE and Metric coverage, quick-change mandrel systems, and robust construction built to handle aluminum, steel, and stainless rivet nuts. Their combination rivet nut and pop rivet setter kit even bundles blind rivet and rivet nut functionality into one complete solution for sheet metal fabrication and fastening.
