About this item

  • High quality steel: galvanised technology to prevent rust and corrosion and ensure long service life. High hardness and high breaking load ensure that the nut is difficult to deform and break. Precise threads and dimensions fit perfectly with the holes and bolts.
  • Quick installation: hand or pneumatic tools make it easier to install. You can use 2 spanners or pliers. One to hold the rivet nut so it doesn't rotate after you have inserted it into the hole. Screw the right size of screw into the nut. Use the other wrench/pliers to tighten the nut. The nut will curl and stay in place as you tighten the screw/bolt. Do not over-tighten or you may strip the threads.
  • Easy to use: equipped with screws for easy installation. Step 1: Insert the jack nut into the recommended drill hole until it is flush with the surface of the substrate; Step 2: Install the instantiation tool on the head of the screw and squeeze to expand the anchor bolt; Step 3: Remove the screw and thread it through the fixture. Tighten the screws on the parts to be attached.
  • Package contains: You will get 80 pieces of M4 x 20 jack nuts. Plenty of them to meet all your daily needs. High quality galvanised steel, galvanised to resist corrosion and rusting.
  • Scope of application: Suitable for hanging curtain rods, lamps, picture frames, wall cabinets, wall panels, coat hangers, lamps, power switches, clocks, car plates, drying racks and container labels.
