• 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 need to reach the back of the workpiece. Simply insert into a pre-drilled hole and compress with a manual or power rivet nut tool — creates strong, permanent threads in thin sheet metal, hollow frames and tubing where conventional nuts can't reach.
• 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.
• 220 PIECES IN 3 SIZES: A complete assortment covering the three small metric sizes used most often in electronics, furniture and light fabrication — M3-0.5 (110 pcs), M4-0.7 (70 pcs), M5-0.8 (40 pcs), 220 pieces in total — sealed in a sturdy, transparent storage case with labeled compartments, so every size stays sorted, protected and ready to grab.
• WIDE APPLICATIONS: These small-size metric rivet nuts create strong, reusable threads in thin sheet metal, aluminum, plastic and fiberglass. Widely used in electronics enclosures, appliance panels, furniture assembly, bicycle maintenance, automotive trim, and general DIY metalworking projects — a practical fastener solution for both professionals and home workshop enthusiasts.
