Premium reclosable fastening solution with 400 stem density mushroom heads, 5X stronger than hook-and-loop, heat and UV resistant, ideal for industrial applications requiring strong, removable attachments.
The 3M™ Dual Lock™ Reclosable Fastener SJ3551CF is a premium industrial fastening solution that provides a convenient alternative to traditional fastening methods such as screws, nuts, and bolts. This innovative product features black, interlocking mushroom-shaped heads with 400 stem density per square inch, delivering exceptional strength through up to 5X the tensile strength of typical hook-and-loop products. The fastener is designed with a clear acrylic tape protected by a removable film liner, offering a solid, pressure-sensitive adhesive that bonds reliably to a variety of substrates including metals, glass, and plastics such as acrylics, polycarbonate, and ABS.
This reclosable fastening system is engineered for durability and design flexibility, allowing for easy positioning of parts before snapping together with an audible verification sound.

With excellent temperature resistance up to 220°F (104°C) and outstanding resistance to heat, chemicals, and UV exposure, this fastener maintains its integrity throughout hundreds of reattachments. The product comes in a convenient 2-inch width by 50-yard roll format, packaged as 1 roll per case, making it ideal for access panels, graphic attachment, specialty vehicle interior attachments, and general industrial applications.
The 3M™ Dual Lock™ Reclosable Fastener SJ3551CF eliminates the need for drilling, screwing, or sewing tools, ensuring quick and easy installation. Its lightweight design provides an aesthetic improvement by remaining hidden beneath surfaces while maintaining material integrity. Compatible with Type 170 and Type 250 stem densities for customizable strength combinations, this fastener is the perfect solution for professionals seeking reliable, versatile, and removable closure systems for both indoor and outdoor use.
