PRODUCT FAQ

  1. What is 3M™ Dual Lock™ Reclosable Fastener SJ3223?

    3M™ Dual Lock™ Reclosable Fastener SJ3223 is a stem density fastener that enables material to be attached and detached for multiple times.

  2. Is it easy to apply on surfaces?

    Yes. It has an interlocking mushroom-shaped head that aligns, then snap together with a firm push until the buttons interlock completely for secure attachment.

  3. How long are the rolls of this fastener?

    The roll measures 1 inch x 50 yards, hence it provides ample length and suitable width for application.

  4. Does it come in different colors or packaging options?

    Yes. Despite being available in black color only, there are eight rolls per case to meet your needs availed either with or without pressure-sensitive adhesive (PSA).

Convenient for Automotive Trim

Ideal for attaching automotive trim components, 3M™ Dual Lock™ Reclosable Fastener SJ3223 provides a high-strength closure that is easy to assemble and just as easy to open and reclose in high cycle applications. Moreover, the pieces audibly snap together with a satisfying click to form a secure, dependable and repeatable attachment.

Designed with hundreds of interlocking mushroom-shaped stems, this polypropylene fastener can replace conventional attachments such as screws or adhesives, which can be time-consuming to fit and assemble, may weaken the part, or are susceptible to vibration and weather extremes. Dual Lock fasteners are constructed with polyolefin stems and hold tight regardless of high heat, cold, moisture or humidity. These fasteners are also an excellent attachment solution when vibration is an issue – not only do the fasteners hold tight, but actually reduce vibration and rattling. The non-woven backing enables attachment to automotive substrates with hot-melt or liquid adhesives.

How It Works

When two pieces of 3M™ Dual Lock™ Reclosable Fasteners are pressed together, 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 opened by simply cleaving or peeling open the closure. Alignment and re-alignment is easy with no special tools required. This means that these fasteners can be used to attach components before they enter the final assembly plant, helping to reduce the number of parts and the length of assembly time.

Stem Densities

Combinations of stem densities and the engaged area provide adjustable and proportional engagement and disengagement force to meet application requirements. Dual Lock fasteners are offered in three different densities (stems per square inch): 170, 250, and 400. The Dual Lock fastener SJ3223 has 250 stems per square inch (25mm), offering the tightest hold, and can be mated to Type 170, 250 or 400.

Recommended Applications

3M™ Dual Lock™ Reclosable Fasteners can replace conventional mechanical fasteners in a wide range of assembly and attachment applications where reclosability or serviceability is desired. Dual Lock fasteners are used primarily to secure rigid and semi-rigid surfaces such as trim or door panels, instrument panel bezels, headliners, and other automotive interior and exterior trim. Other application examples include attaching accessories and equipment, window and door trim panels, sunroof rings and vibration and sound damping control.

3M Science Delivers Closures You Can Count On

3M™ Dual Lock™ Reclosable Fasteners are ideal for many applications where a high strength, reclosable fastening system is required. 3M engineers have uniquely combined physics and materials science to bring the automotive industry reliable fasteners that supply high performance even after exposure to high moisture levels and wide temperature ranges. For applications that require multiple closures, look no further than the long-lasting durability of the 3M™ Dual Lock™ Reclosable Fastener SJ3223. It is yet another outstanding example of how 3M technologies advance operations in the automotive industry, providing both ease of use and superior results.
