3M Dual Lock Reclosable Fastener SJ3792 is a black, polypropylene reclosable fastener with a 31 mm x 24.5 mm, rectangular base that slides into a channel of precise dimension. The base is lined with polyolefin mushroom stems of density 250 per 25mm, and can be paired with other stem densities for varying levels of interlocking strength. Stems provide superior strength over hook and loop closures yet easily peel apart.
- Interlocking mushroom stems snap together for a strong, fast and easy attachment
- Can be opened and re-closed in high cycle applications
- Provides hidden component attachment, preventing disruption on the show surface
- Strong holding power reduces the rattling and vibration of components
- Resistant to high temperature and solvents
- Does not require any special tools or processing equipment for installation

How does the slide-in piece function within the dual lock fastening system?
The slide-in piece serves as one component that allows for easy and secure attachment and reattachment using our patented Dual Lock technology.
3M™ Dual Lock™ Reclosable Fastener SJ3792 is a black, polypropylene reclosable fastener with a 31 mm x 24.5 mm, slide-in, rectangular base and has a stem density of 250 stems per square inch. This fastener is designed to overcome the difficulties of aligning and installing screws and hidden fasteners, offering a simple installation process without the need for special tools. It is a positive-locking, blind fastener specifically designed for attaching automotive trim components. The fastener features mushroom-shaped polyolefin stems that snap together, forming a high tensile closure. It is primarily 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.
How It Works
The 3M™ Dual Lock™ Reclosable Fastener SJ3792 is designed to be inserted into a same-width channel where attachment is desired. The polypropylene base grips the inside of the channel tightly, providing a secure hold. The fastener can then be mated to a second Dual Lock fastener attached to a piece of trim or other part. When the two fasteners mate, the two parts are firmly secured together.
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 provide high tensile strength but can be easily opened by cleaving or peeling open the closure.
Alignment and re-alignment are easy with Dual Lock fasteners, and no special tools are required. This means that components can be attached before they enter the final assembly plant, reducing the number of parts and assembly time.
Stem Densities
Dual Lock fasteners are offered in three different densities (stems per square inch): 170, 250, and 400. The Reclosable Fastener SJ3792 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. They are primarily 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
- Sunroof rings
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. These fasteners have been engineered using physics and materials science to provide the automotive industry with reliable fasteners that maintain high performance even after exposure to high moisture levels and wide temperature ranges. For applications that require a slide-in piece and multiple closures, the 3M™ Dual Lock™ Reclosable Fastener SJ3792 Slide-In Piece Part is the perfect choice, offering long-lasting durability. It is another example of how 3M technologies advance operations in the automotive industry, providing both ease of use and superior results.
