About Marson: A Legacy of Fastening Innovation

Marson is one of the most recognized names in professional fastening tools, operating under the Howmet Fastening Systems family of brands. Marson has built its reputation by delivering a comprehensive lineup of blind rivet tools, rivet nuts, and installation equipment trusted by automotive technicians, OEM manufacturers, aerospace professionals, and industrial repair shops alike.

At the core of the Marson catalog is a commitment to engineering tools that make riveting faster, more precise, and less physically demanding. Marson air rivet guns represent the brand's flagship pneumatic technology, giving high-volume users the speed and consistency needed on production floors and busy body shops. Models like the AH-250 pneumatic riveter are engineered to accept standard nosepieces as well as newly designed nose assemblies, allowing a single tool to handle a variety of rivet types and sizes with minimal changeover time.

For technicians who prefer direct, hands-on control, Marson hand rivet guns have long been a go-to solution. The HP-series and Big Daddy riveters are well-regarded for their ergonomic grip designs and robust construction, handling everything from light aluminum rivets to heavy-gauge steel. The patented HP-4x4 Multiplex Hand Tool takes versatility even further, setting both rivets and rivet nuts across a range of sizes from a single unit.

Marson's expertise extends beyond basic blind rivets into threaded fastening. Their rivet nut tools — including the popular RN-1 setter and the heavy-duty 425RN — are widely used to install rivet nuts, poly-nuts, and thread-serts in thin-gauge materials where traditional threaded holes aren't practical. These tools are an essential addition for anyone doing automotive bodywork, cabinet assembly, or light fabrication. For those looking for a complete out-of-the-box solution, Marson rivet nut tool kits bundle the tool, mandrels, nosepieces, and a carrying case together, making them ideal for technicians who need to get up and running quickly.

Rounding out the lineup, Marson also offers dent removal tools that complement their fastening products in auto body and collision repair environments. Whether you're pulling a panel back into shape before re-riveting a component or restoring a surface after structural repair work, these tools integrate naturally into a shop workflow already built around Marson equipment.
