What is 3M™ Dual Lock™ Reclosable Fastener SJ3788?
3M™ Dual Lock™ Reclosable Fastener SJ3788 is a type of fastener that consists of interlocking mushroom-shaped stems, which can be opened and closed multiple times.
What are its features?
This specific product has a stem density of 400 and comes in black. It is sold as a roll good with PSA (pressure sensitive adhesive) backing, measuring 6 inches by 50 yards.
How do I use it?
To use this product, simply peel off the protective liner to expose the adhesive side. Apply it to your desired surface and press firmly to ensure proper adhesion. The dual-locking mechanism ensures that items will stay securely fastened until you're ready to remove them.
Where can I buy it from?

3M™ Dual Lock™ Reclosable Fastener SJ3788 overcomes the often difficult alignment and installation problems of screws and hidden fasteners. Simple installation does not require special tools or processing equipment. 3M™ Dual Lock™ Reclosable Fasteners are positive-locking, blind fasteners designed for attaching automotive trim components. The products feature mushroom-shaped polyolefin stems that snap together, forming a high tensile closure. 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.
How It Works
This reclosable fastener features mushroom-shaped polyolefin stems that snap together. When two pieces of 3M™ Dual Lock™ Reclosable Fastener 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 are easy and no special tools are required. This means that they can be used to attach components before they enter the final assembly plant, thus helping to reduce the number of parts and the length of assembly time.
3M™ Dual Lock™ Reclosable Fasteners can be mixed and matched to meet the needs of the application. Combinations of stem densities and the engaged area provide adjustable and proportional engagement and disengagement force. Dual Lock fasteners are offered in three different densities (stems per square inch): 170, 250 and 400. The Reclosable Fastener SJ3250 has 400 stems per square inch (25mm), offering the tightest hold, and can be mated to Type 170 or 250. It should not be mated with another Type 400 fastener because the holding power would be so tight that detachment would likely result in damage to the parts.
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. 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 thrives on defying conventional wisdom, like the concept that fasteners can both durably attach and easily separate. 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 SJ3788. It is yet another outstanding example of how 3M technologies advance operations in the automotive industry, providing both ease of use and superior results.
