AP Astro Pneumatic Tool Company 1423 13" Heavy-Duty Hand Riveter — 1/4" Blind Rivet Capacity, Patented Geared Mechanism

Compact yet powerful, this hand riveter is built to reach tight spots and drive large-diameter blind rivets with less user effort. Its one-piece collet case removes the need to reconfigure the tool when switching rivet sizes, and the included nose pieces cover common rivet diameters. Durable construction and adjustable jaw engagement make it a reliable choice for sheet metal, automotive trim, and general maintenance tasks.

How does the 1423 deliver more clamping force with less effort?

The 1423 uses a patented internal geared mechanism and double compound hinges to amplify operator input into greater pulling force on the mandrel. Shortened handle geometry reduces overall hand travel while increasing leverage, so setting large rivets requires noticeably less strain.

• Patented internal gearing converts handle motion into higher pulling power.
• Double compound hinge design maximizes mechanical advantage.
• Short handle reduces hand movement without sacrificing force.
• Operates up to 1/4" (6.4 mm) stainless steel blind rivets.

What rivet sizes and accessories are included?

The tool ships with five interchangeable nose pieces that cover standard blind rivet diameters so you can start work immediately. A one-piece collet case keeps the nose assembly aligned and removes the need to re-index the tool when swapping sizes.

• Includes 1/8", 5/32", 3/16", 1/5", and 1/4" nose pieces.
• One-piece collet case for quick, consistent size changes.
• Adjustable jaw engagement to fine-tune for rivet material and size.

How does it hold up under repeated use and maintenance?

The riveter is engineered for workshop durability with serviceable jaws and a simple adjustment method to maintain consistent gripping performance. Keeping the jaws clean and occasionally adjusting the jaw engagement extends life and preserves setting quality.

• Adjust jaw engagement by threading the top hex head for tighter grip.
• Serviceable internal parts for long-term reliability.
• Robust construction suitable for repeated heavy-duty use.

Where does this tool perform best on the job?

Its compact 13" length and powerful mechanics make the 1423 ideal in crowded or awkward locations where larger tools won’t fit. It excels on tasks where larger blind rivets are required but working room is limited.

• Reaches confined spaces such as behind panels or inside assemblies.
• Sets larger blind rivets for load-bearing or thick-material joins.
• Useful in automotive, HVAC, metal fabrication, and maintenance work.

Who is this for: The Astro Pneumatic 1423 is aimed at mechanics, fabricators, maintenance technicians, and serious DIYers who need a compact riveter capable of handling up to 1/4" blind rivets without an air system. If you frequently work in tight quarters or need a hand tool that combines durability with high leverage, this riveter offers a straightforward, serviceable solution.
