Premium reclosable fastening solution with interlocking mushroom heads offering 5X tensile strength, featuring 250 stem density, synthetic rubber adhesive, and 1000 closure cycles for versatile indoor applications.
3M™ Dual Lock™ Reclosable Fastener SJ3540 is the 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 exceptional strength of up to 5X the tensile strength of typical hook-and-loop products. The fastener is engineered with a synthetic rubber-based black PE foam tape protected by a removable film liner, ensuring quick stick and short dwell time for efficient installation. With no need for drilling, screwing, or sewing tools, this pressure-sensitive adhesive fastener provides quick and easy installation on a wide variety of substrates including low surface energy plastics such as polyethylene and polypropylene.
Designed for versatile indoor applications, the SJ3540 offers exceptional design flexibility through its interlocking mushroom-shaped heads that easily slide over each other, allowing for precise positioning of parts before being snapped together with an audible snap that verifies closure. This durable reclosable fastening system can be opened and closed multiple times—up to 1000 closure cycles—while maintaining consistent strength throughout. The fastener can mate with Type 170, Type 250, or Type 400 stem densities to provide different strength combinations based on specific project requirements, making it ideal for access panels, interior signage, decorative trim, office partitions, and product identification applications.
The 3M Dual Lock SJ3540 comes in a convenient roll format measuring 2 inches wide by 50 yards long, with an engaged thickness of 226 mil (5.8 mm) and a maximum operating temperature of 120°F (49°C). This lightweight alternative to metal fasteners remains hidden beneath surfaces without interfering with material integrity, providing both aesthetic improvements and enhanced design flexibility. Best suited for indoor use in construction, electronics, furniture, general industrial, medical, military and government, packaging, retail, and specialty vehicle applications.
