. What colors does the Dual Lock system come in?
. The SJ3550 series comes in clear, while other variations such as SJ3560 (mated) have standard black mushroom heads.When looking into stronger adhesion bonds and higher cycle life there are different color variations.
Convenient for Automotive Trim
Ideal for attaching automotive trim components, 3M™ Dual Lock™ Reclosable Fastener SJ3754 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 tightly, but actually reduce vibration and rattling.
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 SJ3754 has 170 stems per square inch (25mm), offering the lightest hold, and can be mated to Type 170, 250 or 400.
