3M SJ 3550

3M SJ 3550 Unlock simplicity, super strength, and ultimate ease. The remarkable 3M™ Dual Lock Reclosable Fastener can be opened and closed up to 1,000 times before losing 50% of its original strength, for repeated access or repositioning.
The mushroom heads easily slide over each other allowing positioning of parts before they are snapped together to create a firm fastening attachment.
When mated, the fasteners are hidden from view and leave you with an unbroken surface for a smooth, clean appearance.

Durable and secure, 3M™ Dual Lock™ Reclosable Fastener SJ3550 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.
