Overview

Meet the Astro PRN1 3/8-in capacity pneumatic rivet nut setting kit. Built for versatility, it ships with eight mandrels spanning metric and SAE sizes, enabling quick adaptation to a range of fasteners. The tool delivers an instant air-hydraulic pull, letting you set rivet nuts with a simple pull of the trigger.

Real-world workflow benefits include a free-spinning rear wheel that lets you un-thread rivet nuts when needed, and a compact, rugged body designed for workshop benches and field use alike. With a maximum capacity of M10 for 3/8-in rivet nuts and M6 for 1/4-in stainless variants, this kit handles common sizes with confidence.

Key features at a glance

  • Includes 8 mandrels/nosepieces in the following sizes: M4, M5, M6, M8, M10, 1/4, 5/16, 3/8
  • Instantly set rivet nuts with the pull of the trigger; note that setting 3/8 may require two strokes at pressures below 120 psi
  • Rear-wheel lets you quickly un-thread set rivet nuts (keep mandrel lubricated)
  • 2680 lbs of instant air-hydraulic pulling force
  • Max capacity: M10 (3/8) steel and aluminum rivet nuts; M6 (1/4) stainless rivet nuts

How it helps in practice

Designed for fast, repeatable installs, the PRN1 reduces manual cranking and fatigue. The 3/8-in tool handles larger rivet nuts smoothly, while the included mandrels cover common metric and SAE sizes. The integrated pull mechanism provides controlled, clean setting, paired with a back-wheel for quick adjustments.

Usage tips

  • Keep mandrels lubricated to extend life and maintain smooth operation
  • Verify pressure stays above 120 psi when using the 3/8 tool for best results
  • Use the rear wheel to un-thread rivet nuts when rework is needed

Compatibility and suitability

Ideal for metal fabrication, automotive repair, and maintenance tasks where fast, reliable rivet-nut installation matters. The kit supports metric and SAE sizes and is designed for air-powered workflows in professional settings.
