Shop 3M Dual Lock Reclosable Fastener SJ3551 Black 6in x 50yd In Iraq Best Prices
Industrial-grade black reclosable fastener with interlocking mushroom heads, 400 stem density, rated for 1,000 open/close cycles, 6in x 50yd roll, up to 5X stronger than hook-and-loop alternatives.
The 3M™ Dual Lock™ Reclosable Fastener SJ3551 is an industrial-grade fastening solution featuring interlocking mushroom-shaped heads with 400 stem density per square inch, delivering exceptional strength and durability. This black fastener comes in a 6-inch width by 50-yard roll and can be opened and closed up to 1,000 times before losing 50% of its original strength, making it ideal for repeated access and repositioning applications. The product utilizes a white, acrylic, conformable foam tape with a removable film liner, providing strong adhesion to various substrates including metals and plastics such as acrylics, polycarbonate, and ABS.
Designed as a modern alternative to traditional fastening methods like screws and bolts, the 3M™ Dual Lock™ SJ3551 eliminates the need for drilling, screwing, or sewing tools, enabling quick and tool-free installation. The fastener features an audible snap when secure, verifying closure of the attachment, and can be easily disengaged by simply peeling the pieces apart by hand. With a maximum operating temperature of 200°F (93°C) and excellent heat, chemical, and UV resistance, this fastener is well-suited for both indoor and outdoor applications including access panels, graphic attachment, specialty vehicle interiors, general industrial attachment, and small component fastening.
The Type 400 stem density design provides up to 5X the tensile strength of typical hook-and-loop products while maintaining design flexibility through compatibility with Type 170 and Type 250 stem densities for customized strength combinations. The hidden fastener design creates an unbroken surface for a smooth, clean aesthetic appearance without interfering with material integrity, making it an ideal solution for modern industrial and commercial applications requiring reliable, reusable fastening systems.
