About this item

  • FEATURE: The SJ3550 Dual Lock Reclosable Fastener is a practical alternative to traditional fasteners like screws or bolts. It provides a durable, reclosable solution that can be opened and closed repeatedly, adhering securely to a range of substrates including metals and plastics such as acrylic, polycarbonate, and ABS.
  • HIGH QUALITY: Featuring black interlocking mushroom-shaped heads with 250 stems per square inch, this fastener delivers strong, reliable, and durable fastening. The white acrylic foam tape adheres well to various materials, including metals and plastics like acrylics, polycarbonate, and ABS. It secures with an audible snap and withstands temperatures up to 200°F (93°C).
  • APPLICATION: SJ3550's acrylic adhesive bonds effectively to high surface energy materials such as certain plastics, metals, glass, and lacquered surfaces. It enables quick installation without mechanical tools. Once bonded, the interlocking mushroom stems provide a secure hold but can be easily separated if needed.
  • INSTALLATION AND REMOVAL: At room temperature, this fastener reaches about 50% of its ultimate strength in 20 minutes, 90% in 24 hours, and full strength in 72 hours. To remove, apply alcohol to the tape for easy peeling. Ensure the surface is clean and avoid touching the adhesive to maintain optimal bonding strength.
  • BOND SMOOTH SURFACE: This fastener bonds well to most painted metals and plastics without leaving residue or causing damage. Its specially formulated adhesive works with various paints, powder coatings, and materials including glass, acrylic, polycarbonate, stone, and wood.

Not 3M and not as gripy as ones I have bought before.

I’ve used a lot of hook-and-loop fasteners over the years, and these strips are by far the strongest. I used them to secure a seat cushion to my desk chair, and trust me—the cushion no longer moves. In fact, be certain as to where you want to affix them. The adhesive has very little give when it comes to repositioning a strip.Given the price, I wouldn’t recommend investing in a large cache of these to keep on hand. Use these only when you need added strength and durability.

The 3m dual lock fasteners are always needed. This is a great product to hang most items securely. I use these to stick my ez pass to the windshield. Also use them to stick my garage door controller to the car's dash. The fasteners are heavy duty and stick well to most surfaces. Just the right size to use for many small items. Great product to have on hand when needed.
