- Black fastener is hidden when closed, providing a clean, smooth appearance
- Ideal for indoor and outdoor use to attach doors, flexible solar panels, headliners, access panels, signs and display components
- Medium temperature resistance – up to 140°F (60°C)
- Modified acrylic adhesive bonds to many plastics, powder coated paints and medium to low surface energy materials with little or no surface preparation
- Reclosable system is up to five times stronger than hook-and-loop fasteners
- Snap-in-place installation replaces screws, nails, snaps and rivets
- Type 400 stem density polyolefin fastener mates to type 170 or 250
The remarkable 3M Dual Lock Reclosable Fastener SJ3871 can be opened and closed over and over, up to 1,000 times before losing 50% of the original strength 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 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.
Hear the Snap
“Snap!” It’s the one word that best defines the extensive line of 3M Dual Lock Reclosable Fastener products. Here’s 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. 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.
Lose the Screws
The bond is strong but can easily be detached; just pull apart to disengage and reattach as needed. This means that the 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 – the 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 the innovative fasteners a popular and effective solution.
