Description



This item is brand-new, factory sealed.

  • Black, interlocking mushroom-shaped heads (170 stem density per square inch) provide strong, reliable and durable fastening that can be opened and closed multiple times
  • Strong fastener secures with an audible snap, verifying closure
  • Best suited for indoor use
  • Mates with Type 250 and Type 400 stem densities to provide different strength combinations
  • An alternative to screws and bolts, this hidden fastener provides a snug fit and smooth aesthetic appearance
  • Synthetic rubber-based adhesive bonds well to a variety of substrates including low surface energy plastics such as polyethylene and polypropylene
  • Features good temperature resistance of 120°F (49°C)


3M™ Dual Lock Reclosable Fastener SJ3542 is the easy and clear alternative to traditional fastening methods, such as screws, nuts or bolts. It is designed to deliver a durable, reclosable fastening solution (which can be opened and closed multiple times) which bonds to a variety of substrates including many plastics and low surface energy materials. Durable and secure, 3M Dual Lock Reclosable Fastener SJ3542 has exceptional strength through its interlocking mushroom-shaped heads (170 stem density per square inch), providing up to 5X the tensile strength of typical hook-and-loop products. We designed this fastener with a synthetic rubber-based black PE foam tape protected by a removable, film liner. This pressure sensitive adhesive features quick stick and a short dwell time. With 3M™ Dual Lock Reclosable Fastener SJ3542, there is no need for any drilling, screwing or sewing tools which makes for quick installation.

Design Flexibility

3M™ Dual Lock™ Reclosable Fastener SJ3542 consists of interlocking mushroom-shaped heads that easily slide over each other, allowing for positioning of parts before being snapped together. This fastening process creates a durable attachment and provides fast product assembly with great design flexibility. Our reclosable fasteners can also engage with different stem densities for varying levels of strength and system performance.

3M™ Dual Lock™ Reclosable Fasteners sound an audible snap when secure, which verifies closure of the attachment. To disengage, simply peel the pieces apart by hand. Our fasteners maintain their strength throughout multiple attachments and detachments. A lightweight alternative to metal fasteners, this product remains hidden beneath surfaces and does not interfere with the integrity of your material-providing aesthetic improvements and design flexibility.

Hundreds of Reattachments in a Snap

When two pieces of 3M™ Dual Lock™ Reclosable Fasteners mate, the stems flex and the mushroom heads slide past each other. After passing the opposing mating piece, the stems snap back into their original position and the opposing mushroom heads interlock. These fasteners can provide high tensile strength but can be
