Industrial-grade reclosable fastener with 5x stronger holding power than hook-and-loop, 1,000 reusable cycles, mushroom-head design with hidden closure, black polypropylene backing with modified acrylic adhesive for indoor/outdoor applications.
The 3M™ Dual Lock™ Reclosable Fastener SJ3871 is a revolutionary industrial fastening solution featuring a black polypropylene backing with modified acrylic adhesive. This Type 400 stem density fastener delivers exceptional holding power that is up to five times stronger than traditional hook-and-loop fasteners, making it ideal for demanding industrial applications. The product comes in a convenient 2 roll per case format, with each roll measuring 1 inch wide by 45 yards long, providing ample material for multiple applications.
Designed for both indoor and outdoor use, this reclosable fastener system can be opened and closed repeatedly—up to 1,000 times—before losing 50% of its original strength. The unique mushroom-shaped heads snap together securely when pressed, creating an audible "snap" sound that confirms proper engagement. The fastener remains hidden when closed, providing a clean, smooth appearance that maintains the aesthetic integrity of your finished product. With an engaged thickness of only 0.24 inches and a maximum operating temperature of 180°F (82°C), this fastener is versatile enough for various applications.
The modified acrylic adhesive bonds excellently to many materials including plastics (polyethylene, acrylic, polycarbonate, and ABS), powder-coated paints, and medium to low surface energy materials with minimal surface preparation required. Installation is snap-in-place, eliminating the need for screws, nails, snaps, or rivets, and requires no tools for assembly or removal. This product is backed by a red polyethylene primary liner and is ideal for transportation, electronics, medical devices, packaging, furniture, and construction applications. The Type 400 stem density fastener mates perfectly with Type 170 or 250 fasteners, giving users flexibility in choosing closure strength based on their specific application requirements.
