The 3M™ Dual Lock™ Reclosable Fastener SJ3871 has a modified acrylic adhesive on the back of a black polypropylene reclosable fastener. This product can be used both indoors and outside in a variety of applications; and has a slim 0.24” engaged thickness and long service life.
Our 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.

Hear the Snap
“Snap!” It’s the one word that best defines our 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 our product gives you a
