Professional-grade reclosable fastener with 250 stem density mushroom heads offering 5X stronger tensile strength than hook-and-loop. Reusable hundreds of times with audible snap closure, no tools required. Compatible with multiple stem densities for customized strength applications.
The 3M™ Dual Lock™ Reclosable Fastener SJ3870 is a professional-grade fastening solution designed as a convenient alternative to traditional fastening methods such as screws, nuts, and bolts. This innovative product features interlocking mushroom-shaped heads with 250 stem density per square inch, providing exceptional holding strength of up to 5X the tensile strength of typical hook-and-loop products. The fastener comes in a roll format measuring 1 inch wide by 45 yards long, with 2 rolls per case, making it ideal for high-volume industrial applications.
The fastener utilizes a black, modified acrylic, highly conformable foam tape that bonds exceptionally well to a variety of substrates including metals, powder-coated paints, and plastics such as acrylics, polycarbonate, and ABS. Protected by a removable film liner, this pressure-sensitive foam tape is chemical and UV resistant, ensuring durability in both indoor and outdoor environments. The engaged thickness of 242 mil (6.1 mm) provides substantial holding power while maintaining a low-profile appearance that doesn't interfere with material integrity.
Designed for quick and tool-free installation with no drilling, screwing, or sewing required, the 3M™ Dual Lock™ Reclosable Fastener SJ3870 delivers an audible snap when secure, verifying proper closure. It can be opened and closed hundreds of times without losing strength, making it perfect for access panels, graphic attachments, general industrial applications, and small component fastening. The product is compatible with Type 170, Type 250, and Type 400 stem densities, allowing customization for different strength requirements and system performance.
