    Details

    3M™ Dual Lock™ Reclosable Fastener SJ3550 is the convenient 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 metals and plastics such as acrylics, polycarbonate and ABS.

    Unlock Simplicity

    Durable and secure, 3M™ Dual Lock™ Reclosable Fastener SJ3550 has exceptional strength through its interlocking mushroom-shaped heads (250 stem density per square inch), providing up to 5X the tensile strength of typical hook-and-loop products. We designed this fastener with a white, acrylic, conformable foam tape protected by a removable, film liner. This solid, pressure sensitive foam tape features a strong, durable bond that is heat, chemical and UV resistant. With 3M™ Dual Lock™ Reclosable Fastener SJ3550, there is no need for any drilling, screwing or sewing tools which makes for quick installation.




    3M™ Dual Lock™ Reclosable Fasteners are available in three stem densities to customize for the strength requirements of your project


    Recommended Applications:


    Access panels
    Graphic attachment
    Specialty vehicles (interior attachments)
    General industrial attachment
    Small components



    Design Flexibility

    3M™ Dual Lock™ Reclosable Fastener SJ3550 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.
