Industrial-grade reclosable fastener with interlocking mushroom heads offering 5X tensile strength, supports 1,000+ cycles, temperature resistant to 200°F, ideal for access panels and trim attachment.
The 3M™ Dual Lock™ Reclosable Fastener SJ3552 is an innovative industrial fastening solution featuring interlocking mushroom-shaped heads with 170 stem density per square inch. This product provides exceptional strength through its unique design, delivering up to 5X the tensile strength of typical hook-and-loop products while maintaining the ability to be opened and closed repeatedly. The fastener can withstand up to 1,000 attachment and detachment cycles before losing 50% of its original strength, making it ideal for applications requiring frequent access or repositioning.
Constructed with a white, acrylic, conformable foam tape protected by a removable film liner, the SJ3552 offers superior bonding to a variety of substrates including metals and plastics such as acrylics, polycarbonate, and ABS. The pressure-sensitive foam tape is heat, chemical, and UV resistant, ensuring long-lasting performance in both indoor and outdoor environments. With a maximum operating temperature of 200°F (93°C), this fastener maintains its integrity across diverse applications and climate conditions.
The SJ3552 is supplied in a convenient roll format measuring 1/2 inch wide by 50 yards long, with 4 rolls per case. This reclosable fastener eliminates the need for drilling, screwing, or sewing, providing quick and clean installation. The product mates with Type 250 and Type 400 stem densities, allowing customization of strength combinations for specific project requirements. It is an excellent alternative to traditional fastening methods such as screws, nuts, and bolts, offering a hidden fastener solution that maintains aesthetic appearance while providing a snug, secure fit.
