1-in Dual Lock Fastener

The 3M MP3551 is a black polypropylene foam tape with mushroom-shaped stems that interlock for a secure, reclosable bond. It uses a general-purpose acrylic adhesive on the back and is sold in a five-yard roll.

Replaces screws and rivets

This tape substitutes mechanical fasteners when joining metals, glass or medium-to-high surface-energy plastics and paint. The switch is worthwhile when panels or components must be opened repeatedly for service, because the closure life is rated for 1000 cycles.

Peel-and-stick application

Apply the adhesive side to a clean, dry surface and press firmly; the stems engage with an audible snap when the two halves are pressed together. Misalignment is the main issue — once snapped, the bond resists repositioning, so test-fit before final contact.
