Product Description
When it comes to securing, organizing, displaying, or crafting, 3M 1/2-inch Diameter Dual Lock SJ4570 Low Profile Coins offer a simple, secure, and reliable solution. These fastening dots feature a low surface energy adhesive on the back of a clear polypropylene reclosable fastener. This product is half the thickness of standard 3M Dual Lock Reclosable Fasteners, providing a low profile attachment.
An alternative to screws and bolts, these hidden fasteners provide a snug fit and smooth aesthetic appearance. 1/2-inch Diameter Dual Lock Coins are designed for indoor use and low to medium temperature performance. This product offers temperature resistance up to 158F and can be used with metals such as aluminum and stainless steel; as well as glass, many plastics (polypropylene, polyethylene, polycarbonate, ABS) powder coated paints and medium to low surface energy materials.
3M 1/2-inch Diameter Dual Lock SJ4570 Low Profile Coins consist of interlocking mushroom-shaped heads that easily slide over each other, allowing for positioning of parts before being snapped together. This fastening process creates a durable attachment and provides fast product assembly with great design flexibility. When two pieces of 3M Dual Lock Low Profile Reclosable Fasteners mate, 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. This product is well suited for many indoor applications where versatile reclosable fastening system is required.
3M Dual Lock Reclosable Fasteners sound an audible snap when secure, which verifies closure of the attachment. To disengage, simply peel the dots apart by hand. The fasteners maintain their strength throughout multiple attachments and detachments. A lightweight alternative to metal fasteners, this product remains hidden beneath surfaces and does not interfere with the integrity of your material—providing aesthetic improvements and design flexibility.
Each roll is pressure-sensitive, meaning no heat or additional tools are necessary for activation. Simply peel and stick the dot to the desired surface. This design makes them perfect for temporary or semi-permanent mounting solutions in a variety of environments including homes, classrooms, offices, and workshops. Many consider these a classroom essential and a teacher must have, they also work great for home organizing.
