3/8 Rivet Nut, 30 Pcs 304 Stainless Steel Flat Head Threaded Insert Rivnuts

Key features

• ① 304 Stainless Steel That Resists Rust and Water: Made of real 304 (18-8) stainless steel, these 3/8-16 rivet nuts resist rust and water, so they hold up in damp garages, boats and outdoor projects far longer than plain steel hardware. The 304 body is also softer than carbon steel, so it crushes clean and sets without cracking or stripping the thread. Each rivet nut is 0.669 in long with a grip range of 0.027-0.15 in, and needs a 0.5312 in drill hole. 30 pcs per box.
• ② Knurled Body Holds Tight, Won't Spin: The knurled body bites into the panel as you set it, so the threaded insert stays locked in place and won't spin when you tighten a bolt later. Threads are cut clean and true to size, so bolts thread in smoothly without cross-threading. A drilling size chart is included in the box.
• ③ Works With Standard 3/8-16 Rivet Nut Tools: These riv nuts work with standard 3/8-16 rivet nut tools and hand riveters, so you don't need a special setup to install them. The 304 stainless steel body resists rust and water, holding up in damp garages, boats and outdoor projects far longer than plain steel hardware.
• ④ For Cars, Boats, Appliances and DIY Projects: A practical rivet nut assortment for auto body panels, car audio and speaker installs, boat hardware, appliances, furniture and general DIY repair. Use them anywhere you need strong machine threads in thin sheet metal, fiberglass or plastic where a plain bolt would pull through.
• ⑤ Check Your Drill Size Before You Install: Confirm your setup: these are 3/8-16 SAE UNC flat head rivet nuts, 0.669 in long, with a 0.027-0.15 in grip range for panels in that thickness. Drill a 0.5312 in hole for a clean fit. If you need metric sizes or a different thread pitch, check our other rivet nut sets before ordering.
