This black fastener features interlocking mushroom-shaped heads with 400 stem density per square inch, providing exceptional strength and reliability that can be opened and closed multiple times without degradation. The product comes in a convenient roll format measuring 1 inch wide by 50 yards long, with 2 rolls per case, making it ideal for industrial applications requiring durable, reclosable fastening systems.\n \n This innovative fastening system operates with an audible snap when properly engaged, providing clear verification of secure closure. The non-adhesive back design allows for flexible attachment methods using hot melt, epoxy, or liquid adhesives, giving engineers and manufacturers complete control over the installation process. The fastener maintains excellent temperature resistance up to 220°F (104°C), though actual performance may vary based on the adhesive used. With a closure life of up to 1000 reattachments, this product delivers long-lasting performance suitable for both indoor and outdoor applications.\n \n The 3M™ Dual Lock™ Reclosable Fastener SJ3441 is compatible with Type 170 and Type 250 stem densities, allowing for customized strength combinations based on specific project requirements. This hidden fastener provides a smooth aesthetic appearance without drilling or screwing, making it an excellent alternative to pressure-sensitive adhesives. Constructed with a polyolefin backing material and engineered for industrial use, this product is suited for construction, electronics, furniture, general industrial, medical device, military, packaging, retail, specialty vehicles, and transportation applications.\n \u003c\/div\u003e\n \n \u003c!-- Features section (always included) --\u003e\n \n \u003cdiv class=\"features-section\"\u003e\n
