Professional reclosable fastener with interlocking mushroom heads, 250 stem density, 50-yard roll, clear acrylic adhesive, bonds to metals, glass, and plastics, 1000 closure cycles, temperature resistant to 220°F.
The 3M™ Dual Lock™ Reclosable Fastener SJ3560 is a professional-grade fastening solution featuring clear, interlocking mushroom-shaped heads with 250 stem density per square inch. This innovative product delivers up to 5X the tensile strength of typical hook-and-loop fasteners, providing a durable, reclosable fastening alternative to traditional screws, nuts, and bolts. The fastener bonds excellently to a variety of substrates including metals, glass, and plastics such as acrylics, polycarbonate, and ABS, making it ideal for diverse industrial and commercial applications.
Designed for maximum design flexibility, the 3M™ Dual Lock™ SJ3560 features a clear acrylic adhesive protected by a removable film liner. The stems flex and mushroom heads slide past each other when mating, then snap back into their original position to create a secure, audible closure that verifies attachment. This product can withstand up to 1000 closure cycles, maintaining strength throughout multiple attachments and detachments. With excellent temperature resistance up to 220°F (104°C) and outstanding chemical and UV resistance, this fastener is suitable for both indoor and outdoor applications.
The 3M™ Dual Lock™ SJ3560 comes in a convenient 50-yard roll format with 2 rolls per case. Installation requires no drilling, screwing, or sewing tools, enabling quick and efficient assembly. The fastener can mate with Type 170, Type 250, or Type 400 stem densities to provide customized strength combinations for specific project requirements. This hidden fastener provides a snug fit and smooth aesthetic appearance while remaining hidden beneath surfaces, making it the ideal solution for architectural panels, graphic attachments, specialty vehicles, general industrial applications, and toll transponder installations.
