The 3M™ Dual Lock™ Reclosable Fastener SJ3443 is an innovative fastening solution featuring black interlocking mushroom-shaped heads with 400 stem density per square inch. This industrial-grade fastener delivers exceptional strength with up to 5X the tensile strength of typical hook-and-loop products, providing a durable and reliable alternative to traditional screws, nuts, and bolts. The fastener can be opened and closed multiple times without losing its holding power, making it ideal for applications requiring repeated attachments and detachments. With a non-woven backing, it allows for attachment using hot melt, epoxy, or liquid adhesives, offering maximum design flexibility for various industrial applications.
Designed for professional industrial and occupational use, this reclosable fastener system features 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. The fastener maintains its strength throughout 1000 closure cycles and can engage with different stem densities (Type 170 or Type 250) for varying levels of strength and system performance. With a maximum operating temperature of 200°F (93°C), this fastener is well-suited for both indoor and outdoor applications where high-strength, removable closures are required.
This product comes in a convenient 2 roll per case package, with each roll measuring 1 inch in width and 50 yards in length. The engaged thickness of 0.28 inches (7mm) ensures a secure fit while remaining hidden beneath surfaces. As a lightweight alternative to metal fasteners, the 3M Dual Lock™ Reclosable Fastener SJ3443 provides aesthetic improvements and design flexibility without interfering with material integrity, making it the perfect choice for automotive, construction, consumer goods, electronics, furniture, and specialty vehicle applications.
