Dual Lock

3M Dual Lock Reclosable Fasteners3M3M™ Dual Lock™ reclosable fasteners can solve your design dilemmas—replacing screws, bolts and rivets as a tool-free, seamless fastening system. The industrial fasteners work similarly to hook and loop products, but offer five times the holding strength and are still lightweight. They have interlocking mushroom-shaped stems that “snap” together for strong fastening on one side and 3M™ adhesives to securely adhere to various surfaces on the other.

How to Use
To use the fasteners, simply press together the two sides of interlocking mushroom-shaped stems until you hear an audible snap, indicating the fastener is engaged.

Benefits

  • Strong, yet removable, fastening
  • Lighter weight than mechanical fasteners
  • Offers design flexibility
  • Easy to apply
  • Repositionable
  • Simplifies assembly
  • No surface holes
