The 3M mushroom hasp (Dual Lock) is an openable closure system that is secure and easy to remove. Positive pull and shear strength is great, but can be disassembled quickly if needed. 3M mushroom buckle has fast and safe opening and closing fixing performance, which can replace nuts/bolts, hasps, pins, nails, zippers, welding, etc., giving designers an innovative choice.
Structure: 3M mushroom buckle is composed of two plastic backing strips, with mushroom-shaped plastic protrusions (mushroom heads) on the backing strips, and there are different mushroom heads per square inch, 170, 250, 400 meshes, The higher the mesh, the greater the closing strength. On the back of the mushroom head, you can choose different adhesives or no adhesives according to your needs. When the two pieces of the mushroom buckle are pressed together, the mushroom heads lock into each other and make a snapping sound. But it can be opened if needed and can be reused 1000 times.
