-
Does this product come in different colors and sizes?
The 3M™ Dual Lock™ Reclosable Fastener SJ3751 is available in black color with a stem density of 400, and it comes in a size of 1 inch wide by 50 yards long.
3M™ Dual Lock™ Reclosable Fastener SJ3751 is a revolutionary solution for overcoming the challenges of aligning and installing screws and hidden fasteners. Unlike traditional fasteners, this product offers simple installation without the need for special tools. Designed specifically for attaching automotive trim components, the Dual Lock fasteners feature mushroom-shaped polyolefin stems that securely snap together, creating a high tensile closure. These fasteners are ideal for securing rigid and semi-rigid surfaces such as trim or door panels, instrument panel bezels, headliners, and other automotive interior and exterior trim.
How It Works
The Dual Lock fastener is attached to various substrates using pressure-sensitive adhesive. It can then be mated to a second Dual Lock fastener attached to a piece of trim or another part. When the two fasteners are pressed together, the stems flex and the mushroom heads slide past each other. Once the opposing mating piece is passed, the stems snap back into their original position, and the mushroom heads interlock, creating a secure bond. These fasteners offer high tensile strength but can be easily opened by cleaving or peeling open the closure.
Alignment and re-alignment are effortless, and no special tools are required for assembly. This makes them suitable for attaching components before they enter the final assembly plant, reducing the number of parts and assembly time.
Stem Densities
The Dual Lock fasteners are available in three different densities: 170, 250, and 400 stems per square inch. The SJ3751 fastener, in particular, has 400 stems per square inch, providing the tightest hold. It can be mated with Type 170 or 250 fasteners. However, it should not be mated with another Type 400 fastener as the engagement would be too tight, potentially causing damage to the parts.
Recommended Applications
3M™ Dual Lock™ Reclosable Fasteners are versatile and can replace conventional mechanical fasteners in various assembly and attachment applications where reclosability and serviceability are desired. They are commonly used to secure rigid and semi-rigid surfaces such as trim or door panels, instrument panel bezels, headliners, and other automotive interior and exterior trim. Some examples of applications include vehicle headliners, attaching accessories and equipment, attaching window and door trim panels, vibration and sound damping control, CHMSL cover plates, center console flanges, interior trim, and sunroof rings.
