3M™ Dual Lock™ Reclosable Fastener SJ3465 is a die-cut, round, black, polypropylene reclosable non-adhesive fastener with a rigid back and a 14.3 mm counter-sunk hole in the center that can accommodate a 4.1 mm screw or rivet for easy attachment. This fastener is available in a stem density of 400 stems per square inch.
- Interlocking mushroom stems snap together for a strong, fast and easy attachment
- Can be opened and re-closed in high cycle applications
- Hidden attachment replaces unsightly mechanical fasteners 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
- Can be used to attach components before they enter the final assembly plant, helping to reduce the number of parts and assembly time.
- Audibly snaps together to form a secure, dependable and repeatable attachment
- Mates with other stem densities to achieve a variety of engagement and disengagement forces

Yes, you can use them for both indoor and outdoor applications as they have good resistance to high temperature, water, solvents, UV light etc.
. Is it easy to install this dual lock reclosable fastener by myself?
. Yes, installing this Dual Lock reclosable fastener system is really simple as there are no screws or bolts required for installation; just peel off adhesive backing from both sides and stick them together wherever you want!
3M™ Dual Lock™ Reclosable Fastener SJ3465 overcomes the often difficult alignment and installation challenges 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
This reclosable fastener is designed to be attached to a substrate using a screw or rivet. 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 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 Dual Lock™ fasteners can be used to attach components before they enter the final assembly plant, helping to reduce parts and assembly time.
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. Dual Lock fastener SJ3465 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 engagement 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 be easily separated. 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 reclosability or serviceability, look no further than the long-lasting durability of 3M™ Dual Lock™ Reclosable Fastener SJ3465. It is yet another outstanding example of how 3M technologies advance operations in the automotive industry, providing both ease of use and superior results.
