This fastener allows for easy and convenient attachment to a variety of substrates.

Delivers Durability
3M™ Flame Resistant Hook Fastener SJ3419FR is our flame resistant fastener with 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. This fastener should be paired with 3M™ Flame Resistant Loop Fastener SJ3418FR. To ensure stability and flatness, both the hook and the corresponding loop are preshrunk.

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.
