• PREMIUM MATERIALS: Crafted from high-quality carbon steel with a zinc-plated finish, these rivet nuts deliver dependable corrosion resistance and long-lasting durability — ideal for both indoor and outdoor projects, from garage repairs to workshop builds.
• INSTALL FROM ONE SIDE, NO WELDING NEEDED: Simply insert into a pre-drilled hole and compress with a manual or power rivet nut tool — creates strong, permanent UNC threads in thin sheet metal, hollow frames and tubing where conventional nuts can't reach. No access to the back side, no welding, no back bolts required.
• FLAT HEAD & KNURLED BODY: The flat head sits flush for a clean, professional finish, while the knurled body embeds into the material during installation to resist rotation and prevent loosening under vibration — a secure, slip-free hold every time.
