• Closes with an audible snap
• Five times the tensile strength of typical hook-and-loop fasteners
• Opens and closes 1000 times before losing 50% of its original tensile strength
• Designed to bond to metals, glass and medium to high surface energy plastics and paint
• Foam tape backing allows for better contact with textured or irregular surfaces

3M™ Dual Lock™ Reclosable Fastener SJ3551 is a convenient alternative to traditional fastening methods, such as screws, nuts or bolts. It is designed to deliver a durable, reclosable fastening solution (which can be opened and closed multiple times) which bonds to a variety of substrates including metals and plastics such as acrylics, polycarbonate and ABS.

3M™ Dual Lock™ Reclosable Fastener SJ3551 solves attachment issues without the use of special tools or complicated, mechanical fastening systems. Our reclosable fastener uses an acrylic adhesive that bonds well to a variety of high and medium surface energy materials, including some plastics, metal, glass, and painted surfaces. This allows you to attach access doors, panels, signs, display components, and many other frequently opened and closed parts for easy, repeated access with minimal loss of bonding strength over time. This reclosable fastener has 26 mushroom shaped stems / cm² (170 per square inch) with a 5.8 mm engaged thickness.

Suggested Applications

• Apply to metals, glass and medium to high surface energy plastics and paints
• Apply on a variety of substrate or material combinations
• Use for fabricating or die-cutting into various lengths and shapes
