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.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the PRN1 set rivet nuts so fast?\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eInstant air-hydraulic pulling force rated at 2680 lbs for rapid setting.\u003c\/li\u003e\n  \u003cli\u003eTrigger-actuated pull stroke for one-handed operation and faster cycle times.\u003c\/li\u003e\n  \u003cli\u003eFree-spinning rear wheel for quick unthreading and mandrel release.\u003c\/li\u003e\n  \u003cli\u003eCompact pistol-style body to access tight assembly locations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich sizes and materials will the PRN1 handle?\u003c\/h3\u003e\n\u003cp\u003eThe 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.
