3M™ Dual Lock™ Reclosable Fasteners DL400H/5361, 20mm x 10mm, 2250 each per case

Designed with hundreds of interlocking mushroom-shaped stems, this fastener offers strong, fast, and easy attachment for automotive assembly applications. This polypropylene reclosable fastener utilizes 3M Acrylic Foam Tape technology to provide an excellent bond after full adhesion. With 400 stems per square inch, it mates to Type 170, 250, or 400. The interlocking mushroom-shaped heads deliver exceptional tensile strength and can be easily attached and detached multiple times. This reclosable fastener offers reliable durability with its temperature, moisture, and UV resistance, ensuring satisfying, long-term performance. Additionally, it secures with an audible snap to help confirm closure engagement.

3M Acrylic Foam Tape 5361 is specifically designed for durable and reliable attachment of moldings, trims, emblems, and other applications requiring high initial and final adhesion to automotive surfaces. This OEM attachment tape is built on a core of viscoelastic medium-density acrylic foam, providing a blend of strength and conformability for a flush, professional appearance. The pressure-sensitive adhesive is applied to both sides of the foam core, offering high initial adhesion, high final adhesion, and peel performance. It is formulated for a variety of automotive substrates, including plastics and automotive paint systems.

When two pieces of 3M Dual Lock Reclosable Fasteners are pressed together, the stems flex, allowing the mushroom heads to slide past each other and interlock. These fasteners provide high tensile strength but can be easily opened by cleaving or peeling open the closure. Alignment and re-alignment are effortless, and no special tools are required for installation. This means that Dual Lock fasteners can be used to attach components before they enter the final assembly plant, reducing the number of parts and assembly time. They are well-suited for many applications where a high-strength, reclosable fastening system is required. Many 3M Dual Lock Reclosable Fastener products maintain good performance even after exposure to high moisture levels and wide temperature ranges.

At 3M, we challenge conventional wisdom and believe 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. Our engineers have combined physics and materials science to bring the automotive industry reliable fasteners that advance operations, providing both ease of use and superior results.
