PRODUCT FAQ
-
What is the stem density of the 3M™ Dual Lock™ Reclosable Fastener SJ3752?
The stem density of the SJ3752 is 170 stems per square inch, providing a strong and secure hold.
-
How long is each roll in the 8 Roll/Case packaging?
Each roll contains 50 yards (150 feet) of the black reclosable fastener, offering ample length for various applications.
-
Does this product come with a pressure-sensitive adhesive (PSA)?
Yes, the SJ3752 features a pressure-sensitive adhesive backing that makes it easy to apply onto different surfaces for quick installation.
-
Can this Dual Lock fastener be used for functional splicing applications?
Absolutely! The SJ3752 is designed for functional splicing purposes, offering durability and reliability in joining materials or components together.
3M Dual Lock Reclosable Fastener SJ3752 overcomes the often difficult alignment and installation problems of screws and hidden fasteners, offering simple installation with no special tools required. 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
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 are easy and no special tools are required for installation. This means that they can be used to attach components before they enter the final assembly plant, helping to reduce the number of parts and assembly time.
Stem Densities
Combinations of stem densities and the engaged area provide adjustable and proportional engagement and disengagement force to meet the needs of the application. Dual Lock fasteners are offered in three different densities (stems per square inch): 170, 250 and 400. The Dual Lock fastener SJ3752 has 170 stems per square inch and mates to Type 250 or 400. Types 170 and 400 should not be mated with another fastener of the same density.
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. 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. 3M engineers have uniquely combined physics and materials science to bring the automotive industry reliable fasteners that supply high performance even after exposure to ultraviolet radiation, high moisture levels and wide temperature ranges. For applications that require a slide-in piece and multiple closures, look no further than the long-lasting durability of the 3M Dual Lock Reclosable Fastener SJ3752. It is yet another outstanding example of how 3M technologies advance operations in the automotive industry, providing both ease of use and superior results.
