Clear reclosable fastener with interlocking mushroom heads for strong, durable, and removable bonding. 250 stem density, 0.75 inch width, 50 yard length, 2 rolls per case. Perfect alternative to screws and bolts with 1000 closure cycles.
The 3M™ Dual Lock™ Reclosable Fastener SJ3560 is a revolutionary fastening solution designed as a convenient alternative to traditional fastening methods such as screws, nuts, and bolts. This product features clear, interlocking mushroom-shaped heads with 250 stem density per square inch, providing exceptional strength and durability. The fastener delivers up to 5X the tensile strength of typical hook-and-loop products, making it ideal for demanding industrial applications. With a clear acrylic adhesive backing protected by a removable film liner, this pressure-sensitive tape bonds reliably to a variety of substrates including metals, glass, and plastics such as acrylics, polycarbonate, and ABS. The product comes in rolls measuring 3/4 inch wide by 50 yards long, with 2 rolls per case, providing ample material for various projects.
Designed for quick and easy installation without the need for drilling, screwing, or sewing tools, the 3M™ Dual Lock™ Reclosable Fastener SJ3560 offers exceptional design flexibility and ease of use. The fastener features interlocking mushroom-shaped heads that easily slide over each other, allowing for precise positioning of parts before being snapped together with an audible click that verifies closure. The product maintains its strength throughout multiple attachments and detachments, with a closure life of up to 1000 cycles, making it suitable for applications requiring frequent opening and closing. The clear, acrylic adhesive is heat, chemical, and UV resistant, with a maximum operating temperature of 220°F (104°C), making it suitable for both indoor and outdoor applications.
The 3M™ Dual Lock™ Reclosable Fastener SJ3560 is engineered to mate with Type 170, Type 250, or Type 400 stem densities, providing different strength combinations to meet specific project requirements. This versatile fastener is ideal for architectural panels, graphic attachment, specialty vehicle interior attachments, general industrial attachment, and toll transponder mounting. The product remains hidden beneath surfaces, providing aesthetic improvements without interfering with material integrity. To disengage, simply peel the pieces apart by hand, making it an ideal solution for temporary or semi-permanent fastening needs.
