AP Pneumatic Rivet Nut Setter Kit PRN1 — 3/8" Capacity, Air-Hydraulic Power & 8 Mandrels (Metric/SAE)

The AP Astro PRN1 is a pneumatic rivet nut setter that loads, pulls and releases threaded rivet nuts up to 3/8" quickly using an air-hydraulic mechanism.

This compact kit pairs a high-force pneumatic actuator with eight interchangeable mandrels so you can install or unthread rivet nuts in both metric and SAE sizes without swapping tools. Built for technicians, fabricators and assembly lines, the PRN1 delivers instant pulling force and a fast trigger action to speed repetitive work while the free-spinning rear wheel eases mandrel removal.

How does the PRN1 set rivet nuts so fast?

The unit converts compressed air into an air-hydraulic pulling stroke that compresses and sets the rivet nut in one motion. A simple trigger controls the pull, and the tool returns quickly for the next cycle, keeping throughput high during repetitive installations.

• Instant air-hydraulic pulling force rated at 2680 lbs for rapid setting.
• Trigger-actuated pull stroke for one-handed operation and faster cycle times.
• Free-spinning rear wheel for quick unthreading and mandrel release.
• Compact pistol-style body to access tight assembly locations.

Which sizes and materials will the PRN1 handle?

The kit ships with eight mandrels and nosepieces to cover common metric and SAE rivet nut sizes, letting you work across mixed fastener inventories without losing time changing tooling. Capacity limits are specified for different materials to match strength and deformation characteristics.

• Mandrels included: M4, M5, M6, M8, M10, 1/4", 5/16", 3/8".
• Max capacity: up to M10 (3/8") in steel and aluminum rivet nuts.
• Stainless capacity: up to M6 (1/4") for corrosion-resistant fasteners.
• May require two pull strokes at lower working pressures (<120 psi) for the largest size.

What maintenance and operation tips keep the PRN1 reliable?

Routine lubrication and correct mandrel selection extend tool life and ensure consistent installation quality. The rear free-spinning wheel makes removal of the mandrel simple, but keeping threads and moving parts lubricated prevents premature wear.

• Keep mandrels lubricated according to the manufacturer to reduce thread galling.
• Inspect nosepieces and replace any that show wear for proper rivet compression.
• Use recommended air pressure; below 120 psi may need multiple strokes on large nuts.
• Store mandrels and nosepieces in a dry, organized case to avoid damage between jobs.

How does the PRN1 improve workshop productivity?

By consolidating multiple mandrel sizes into one pneumatic tool, the PRN1 reduces tool changes and hand fatigue compared with manual nut setters. Fast pull cycles and quick-release unthreading speed through repetitive installations on panels, enclosures and structural work.

• One tool covers both metric and SAE common sizes, minimizing inventory on the bench.
• High instantaneous pulling force for clean, repeatable set-ups in thicker materials.
• Ergonomic trigger and compact body reduce operator strain during long runs.
• Quick unthreading function decreases downtime between rivet nut removals or adjustments.

Who is this for: The AP Astro PRN1 pneumatic rivet nut setting kit is aimed at professional mechanics, metal fabricators, production assemblers and maintenance teams who need a dependable, fast method to install threaded rivet nuts across mixed-size jobs. If you work with steel, aluminum or stainless rivet nuts in assemblies, and you want to cut cycle times while keeping consistent clamp and thread engagement, this kit supplies the mandrels and the pulling force to handle most workshop demands.
