3M™ Dual Lock™ Reclosable Fastener SJ4570 allows you to replace conventional fasteners, such as screws, clips, rivets, snaps, hook and loop and bolts in many applications where access or repositioning is needed. As tough, polyolefin mushroom-shaped stems snap together, they give you both the tensile strength to replace traditional fasteners and a cleaner looking result.
Low profile, polyolefin fastener is half the thickness of standard 3M Dual Lock reclosable fasteners and is self-mating
Snap-in-place installation replaces screws and nails, snaps, and rivets
Clear fastener allows color and patterns to show through, creating an almost invisible appearance
Acrylic adhesive bonds well to metals, glass, paint, and low surface energy plastics
Ideal for many applications such as attaching speaker grills, screen doors, muntin bars, access panels, signs, display components, and multi-media packaging
Our remarkable, low profile version is thinner and more flexible than similar reclosable fasteners and can be opened and closed up to 100 times for repeated access or repositioning. The mushroom heads easily slide over each other allowing positioning of parts before they are snapped together to create a firm fastening attachment. When mated, the fasteners are hidden from view and leave you with an unbroken surface to help create a smooth, clean appearance.
The pressure-sensitive, low surface energy acrylic adhesive provides a good adhesion for many applications and adheres well to metals, glass, and many plastics, powder coated paints, and medium to low surface energy materials. Additionally, 3M Dual Lock™ Reclosable Fastener SJ4570 Low Profile Clear will adhere well on powder-coated paint, polyolefin, and surfaces lightly contaminated with oil as well as acrylic, sealed wood, glass, metal, foam and fiberglass.
Our flexible fastener is a popular choice for POP (point of purchase), trade show exhibition and electronics. 3M Dual Lock low profile reclosable fasteners are well suited for attaching ceiling tiles, carpet, seat cushions, trade show graphics, access panels, wall panels and small electronic devices. For a quick grab attachment with intermediate strength and limited cycle life, any of the 3M Dual Lock reclosable fastener products can be mated with 3M™ Hook and Loop Reclosable Fasteners.
How it works
When two pieces of 3M Dual Lock Reclosable Fastener are pressed together, the stems flex and the mushroom heads slide past each other. After passing the mushroom heads on the opposing mating piece, a stem snaps up into its original position, interlocking with the opposing heads. The audible snap signals the fastener is engaged. The attachment formed may be as effective as screws or rivets, but will peel apart for repositioning. 3M Dual Lock reclosable fasteners are used extensively in transportation, electronics, business equipment, machinery, medical, and sign and display markets. Applications include attaching signs, enclosure panels, banners, repositionable shelving, vehicle ceiling panels, furniture seats and backs, marine carpeting, and orthopedic brace closures.
Today, designers, manufacturers, and consumers expect more options to secure, attach and connect surfaces. 3M Dual Lock Reclosable Fasteners offer instant installation and high-strength attachment, yet can be opened as easily as zippers. That functional flexibility, as well as superior aesthetics, reduced weight, and savings in labor and installation costs, make these innovative fasteners a popular and effective solution.
