Hillman 59127 Long Jack Nuts 15-Pack - 1/4-20 Inch Zinc Blind Fasteners For Thin Materials

About This Product

Hey DIYers and repair pros, these Hillman jack nuts are seriously handy little fasteners that solve that annoying problem of mounting things to thin, soft, or brittle materials like plastic panels or thin sheet metal. The 1/4-20 thread size matches standard machine screws, and the way these work is pretty clever - when you tighten a screw into them, the body collapses to form four little legs that grip the inside of your mounting surface, creating a permanent but reusable threaded insert. The zinc plating gives them solid rust resistance, which is great for outdoor projects or anywhere moisture might be an issue. What's really nice is they don't distort or damage delicate materials like cheap plastic fasteners often do. You get 15 in the pack, which is perfect for having extras on hand for future projects. Installation is straightforward with a friction wrench (not included, but easy to find), and they work with both manual tools or pneumatic if you're doing production work. We've used these for everything from securing electronics in plastic enclosures to mounting accessories on automotive panels where you can't get behind the surface. The quality feels substantial - they're made from good steel that won't strip out easily. Whether you're working on cars, electronics, furniture, or any project where you need a reliable fastener in materials that can't support traditional nuts, these jack nuts deliver that professional solution without the headache.
