Overview
3M Dual Lock Reclosable Fastener SJ3445 is the easy and clear alternative to traditional fastening methods, such as screws, nuts or bolts. It is designed to deliver a durable, reclosable fastening solution, which can be opened and closed multiple times. This fastener is most commonly attached by applying hot melt, epoxy or liquid adhesive.

Unlock Simplicity
Durable and secure, 3M™ Dual Lock™ Reclosable Fastener SJ3445 has exceptional strength through its interlocking mushroom-shaped heads (250 stem density per square inch), providing up to 5X the tensile strength of typical hook-and-loop products. With 3M™ Dual Lock™ Reclosable Fastener SJ3445, there is no need for any drilling or screwing.

Recommended Applications:

  • Alternative to pressure sensitive adhesives

Design Flexibility
3M™ Dual Lock™ Reclosable Fastener SJ3445 consists 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. Our reclosable fasteners can also engage with different stem densities for varying levels of strength and system performance.

3M™ Dual Lock™ Reclosable Fasteners sound an audible snap when secure, which verifies closure of the attachment. To disengage, simply peel the pieces apart by hand. Our 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.

Hundreds of Reattachments in a Snap
When two pieces of 3M™ Dual Lock™ 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 a good performance, high strength, reclosable fastening system is required.

Delivers Long-Lasting Performance
Not all design requirements are easily satisfied, but you can simplify your attachments. When you need a strong, reliable, yet removable closure, 3M™ Dual Lock™ Reclosable Fasteners are the easy alternative to traditional fastening methods such as screws, nuts or bolts.
