Industrial-grade reclosable fastener with interlocking mushroom heads, 250 stem density, providing 5X tensile strength of traditional hook-and-loop. Reusable up to 1000 cycles with audible snap verification. Ideal for construction, electronics, and manufacturing applications.
The 3M™ Dual Lock™ Reclosable Fastener SJ3445 is an innovative, industrial-grade fastening solution designed as a superior alternative to traditional screws, nuts, and bolts. This high-performance fastener features interlocking mushroom-shaped heads with 250 stem density per square inch, delivering exceptional tensile strength up to 5X that of typical hook-and-loop products. The fastener is engineered for easy attachment using hot melt, epoxy, or liquid adhesives, with a non-woven backing that ensures reliable bonding across various surfaces and substrates.
This reclosable fastening system provides unparalleled design flexibility and durability, capable of withstanding hundreds of reattachments without losing strength or performance. When two pieces mate, the stems flex and mushroom heads interlock with an audible snap, verifying secure closure. Disengagement is simple—just peel the pieces apart by hand. The product maintains its structural integrity through repeated open-and-close cycles, with a closure life rating of 1,000 cycles. With an engaged thickness of 0.28 inches (7mm) and maximum operating temperature of 200°F (93°C), this fastener is well-suited for both indoor and outdoor applications across diverse industries including construction, electronics, furniture, automotive, and general manufacturing.
The 3M Dual Lock SJ3445 comes in a convenient 2-roll case configuration, with each roll measuring 1 inch wide by 50 yards long. This product is specifically formulated for industrial and occupational use, offering superior performance compared to pressure-sensitive adhesive alternatives. The hidden fastening design provides aesthetic improvements while maintaining structural integrity, making it an ideal choice for applications requiring both strength and design flexibility. Compatible with Type 170, Type 250, and Type 400 stem densities, this fastener allows customization of strength combinations to meet specific project requirements.
