3M™ Dual Lock™ Reclosable Fasteners – Strong, Clean, Reusable Mounting

3M™ Dual Lock™ Reclosable Fasteners offer a high-strength, reliable alternative to screws, bolts, and traditional hook-and-loop. Built with interlocking mushroom-shaped stems, Dual Lock provides a powerful “snap” engagement that holds panels, signage, devices, access doors, and components securely in place—yet removes cleanly whenever needed.

Ideal for industrial assembly, automotive interiors, retail displays, access panels, electronics, and removable mounting applications, Dual Lock fasteners improve productivity with tool-free installation and long-lasting acrylic adhesive backing made with 3M™ VHB™ Tape Technology.

Available in a range of stem densities—170, 250, and 400—and in black or clear varieties, 3M™ Dual Lock™ allows you to tailor the exact holding strength your job requires. Whether you need a strong permanent-feeling attachment or a lighter, easy-reopen connection, Dual Lock delivers consistent performance for thousands of open/close cycles.
