Pneumatic Rivet Nut Gun (M4-M12, Auto Self-Locking Head)

Pneumatic rivet nut gun that sets threaded inserts quickly in sheet metal, tubing and panels for strong, reusable thread points. The tool installs rivet nuts from M4 through M12 by pulling the mandrel with compressed air, so even blind-side fastening takes seconds instead of minutes with hand tools. Interchangeable mandrel heads snap in to match the insert size, and the self-locking nose holds the rivet nut securely while the stroke pulls it tight against the material. The comfortable grip and high pulling force reduce operator fatigue across production runs, while the faster cycle time keeps assembly lines moving. A protective nose tip and rugged body stand up to daily shop use, and the tool runs on any standard workshop compressor. Ideal for automotive bodywork, sheet-metal fabrication, appliance assembly and metal furniture manufacturing where reliable thread inserts in thin materials are required.
