AP Astro Pneumatic Tool Company 13" Hand Riveter Kit — 6 Mandrels, Quick-Change Head, Ergonomic 13in Nut/Thread Riveter

The Astro 1442 is a compact, high-leverage 13" hand riveter kit that installs threaded rivet nuts quickly using a toolless quick-change head and six interchangeable mandrel/nosepiece sets.

Built to make rivet nut installation less strenuous and more precise, this handheld kit combines an ergonomic handle with a patented internal mechanism that raises pull force while softening recoil. The kit arrives with metric and SAE mandrels plus a generous rivet nut assortment so you can start fastening in automotive, fabrication, and maintenance jobs right away.

How does the quick-change head speed up work?

The tool’s toolless quick-change head lets you swap mandrels and nosepieces by hand without disassembling the riveter. A spring-loaded inner hex sleeve locks the mandrel automatically, preventing unwanted rotation and keeping changes fast and secure.

• Hand-changeable mandrels and nosepieces — no extra tools needed
• Spring-loaded inner hex sleeve locks mandrels for reliable operation
• Reduces downtime when switching sizes on mixed-size projects

What makes the handle design better for tough jobs?

The shorter handle uses a double compound hinge system to maximize leverage so less hand force is needed when setting rivet nuts. That mechanical advantage is helpful when working overhead or in cramped areas where long handles are awkward.

• Short 13" overall length for tight-space access
• Double compound hinges increase pulling force without extra effort
• Ergonomic grip for more comfortable repeated use

Which sizes come with the kit and what applications fit them?

This kit includes three metric mandrels (M5, M6, M8) and three SAE mandrels (10-24, 1/4-20, 5/16-18), plus ten rivet nuts of each corresponding size. Those sizes cover common sheet-metal repairs, accessory mounting and off-road or vehicle modification needs.

• Metric mandrels: M5, M6, M8 — for many European or machine-threaded fittings
• SAE mandrels: 10-24, 1/4-20, 5/16-18 — fits typical U.S. fasteners and accessories
• Includes 10 rivet nuts per size so you can begin multiple installations immediately

How durable and serviceable is the riveter?

The patented internal structure boosts durability by concentrating force and reducing shock to the tool and operator. Because the quick-change design and locking sleeve eliminate frequent disassembly, routine maintenance is simpler and fewer parts wear prematurely.

• Patented internal mechanism reduces operator shock and tool strain
• Minimal disassembly required due to the self-locking mandrel system
• Sturdy construction suited to garage, shop, or field environments

Who this is for: The Astro 1442 is aimed at mechanics, fabricators, off-road enthusiasts, and maintenance professionals who need a portable, easy-to-use rivet nut solution. It’s particularly useful when working in confined spaces or when you require quick switching between metric and SAE sizes. If you want a rugged hand riveter with a fast-change head and a ready-to-use rivet nut assortment, this kit delivers the necessary sizes and leverage to get the job done efficiently.
