Delivers Durability
3M™ Hook Fastener SJ3402 is our general purpose hook fastener that features no adhesive or liner. It is an attachment alternative to a wide variety of closures, including zippers, screws, snaps, hooks and more. This fastener is covered with flexible J-shaped hooks, about 300 hooks per square inch (46 hooks/square cm.), which protrude up from a woven backing. Commonly paired with 3M™ Loop Fastener SJ3401, this hook fastener can also engage with other 3M™ Loop Fasteners. To ensure stability and flatness, both the hook and the corresponding loop are preshrunk.

No Adhesive or Liner for Easy Customization
The backing of 3M™ Hook Fastener SJ3402 is free of adhesive or liner, allowing for easy customization. The fastener is most commonly attached by sewing, but can also be applied using hot melt or liquid adhesives (temperature resistance may change based on adhesive used). It provides a tailored appearance for fabrics and garments and is both washable and dry cleanable.
Secure, Repeated Closures
3M™ Hook and Loop Fasteners offer great design flexibility, fast product assembly, smooth and clean exterior surfaces and excellent product performance in many applications. 3M Hook and Loop Fasteners consist of hooks and loops which engage to form a quick fastening attachment. To disengage the attachment, simply pull the strips apart by hand.

Simply press together and the tiny, stiff hooks mesh with pliable loops to create a quick, secure fastening system. Backed with a variety of 3M adhesive technologies, you can easily meet application demands that require thousands of easy opening and closings.
