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.
3M™ Dual Lock™ SJ3551 has mushroom shaped heads that snap together. This product is Type 400 meaning it has 400 stems / square inch which indicates the relative holding power. Other options include Type 170 with 170 stems per square inch, Type 250 has 250 stems per square inch, and so on. More stems mean a tighter grip and is almost a permanent closure when mated to itself or other Type 400 Dual Lock material.
The adhesive backing also varies between product options. This product features VHB or “very high bond” acrylic adhesive for applications requiring a more secure bond.
