Professional-grade reclosable fastener with interlocking mushroom heads providing 5X tensile strength, audible snap verification, and up to 1000 reusable cycles for reliable indoor fastening applications
The 3M™ Dual Lock™ Reclosable Fastener SJ3540 is an innovative alternative to traditional fastening methods such as screws, nuts, and bolts. This premium fastening solution features interlocking mushroom-shaped heads with 250 stem density per square inch, delivering up to 5X the tensile strength of typical hook-and-loop products. The fastener is constructed with a synthetic rubber-based black polyethylene foam tape protected by a removable film liner, utilizing a pressure-sensitive adhesive with quick stick properties and short dwell time. Designed for easy installation without drilling, screwing, or sewing tools, this reclosable fastener can be opened and closed multiple times while maintaining its exceptional strength and durability.
The SJ3540 fastener mates seamlessly with Type 170, Type 250, or Type 400 stem densities, providing flexible strength combinations for varied application requirements. Its synthetic rubber-based adhesive bonds effectively to a wide variety of substrates, including low surface energy plastics such as polyethylene and polypropylene. The fastener features an audible snap when securely closed, verifying proper closure of the attachment. With a maximum operating temperature of 120°F (49°C) and closure life of 1000 cycles, this product delivers long-lasting performance for indoor applications requiring reliable, removable fastening solutions.
Ideal for applications including access panels, interior signage, decorative trim, office partitions, and product identification systems, the 3M Dual Lock SJ3540 provides design flexibility and aesthetic improvements. The fastener maintains its strength throughout multiple attachments and detachments, offering a lightweight alternative to metal fasteners that remains hidden beneath surfaces without interfering with material integrity. Each case contains 4 rolls of 50-yard length, with a 0.5-inch width, making it suitable for both small-scale and large-scale industrial assembly projects.
