Professional-grade reclosable fastener with 400 stem density mushroom heads, 5X stronger than hook-and-loop, synthetic rubber adhesive, 1 inch x 50 yard rolls, rated for 1000 closure cycles
The 3M™ Dual Lock™ Reclosable Fastener SJ3541 is a professional-grade fastening solution designed to replace traditional screws, bolts, and nuts. Featuring interlocking mushroom-shaped heads with 400 stem density per square inch, this fastener delivers exceptional strength with up to 5X the tensile strength of typical hook-and-loop products. The black synthetic rubber-based adhesive bonds securely to a variety of substrates including low surface energy plastics such as polyethylene and polypropylene, making it ideal for diverse industrial applications.
This innovative reclosable fastening system can be opened and closed multiple times without losing its strength, providing hundreds of reattachments in a snap. 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 removable film liner and pressure-sensitive adhesive that offers quick stick and short dwell time, installation requires no drilling, screwing, or sewing tools, making for fast and efficient assembly.
The SJ3541 comes in a 2 roll per case package, with each roll measuring 1 inch wide by 50 yards long. Designed for indoor applications, it maintains excellent performance with a maximum operating temperature of 120°F (49°C) and provides a closure life of 1000 cycles. This product is particularly well-suited for access panels, interior signage, decorative trim, office partitions, and product identification applications in construction, electronics, furniture, and general industrial settings.
