When mated, the fasteners are hidden from view, leaving you with an unbroken surface to help create a smooth, clean appearance. The type 400 stem density polyolefin fastener mates to type 170 or 250, giving the user the option of different closure strength depending upon application.

This fastener is backed by a modified acrylic adhesive that bonds to many plastics (polyethylene, acrylic, polycarbonate, and ABS), powder-coated paints, and medium to low surface energy materials with little or no surface preparation.

"Snap!" It's the one word that best defines the extensive line of 3M™ Dual Lock™ Reclosable Fastener products. 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. Listen for the audible snap to signal that 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.

The bond is strong but can easily be detached; just pull apart to disengage and reattach as needed. This means that this product gives you a strong, hidden closure with the convenience of multiple openings and closings so you can lose the screws, rivets, hooks, bolts, zippers, and other unsightly attachment methods. In short – this product is an aesthetically pleasing fastener that doesn't sacrifice attachment strength. In fact, the 3M™ Dual Lock™ Reclosable Fastener SJ3871 is about five times stronger in tensile strength than 3M Hook and Loop fasteners used in comparable applications. In many cases, this attachment method also saves the user money with less material used. Additionally, there's no need to drill holes that might weaken the part or substrate, and no tools required to assemble or remove the part.

You expect more options to secure, attach, and connect surfaces. 3M Dual Lock Reclosable Fasteners offer quick 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 innovative 3M fasteners a popular and effective solution.
