3M Dual Lock SJ3560 Clear Fastener

The 3M Dual Lock SJ3560 is a general-purpose clear reclosable fastener featuring 250 stems per square inch. It uses mushroom-shaped stems on a polypropylene carrier coated with a white acrylic pressure-sensitive adhesive. The engaged thickness measures .23 inches and offers a closure life of 1000 cycles. It suits makers and technicians needing detachable mounting for panels, displays or electronics.

Check surface compatibility before ordering

This fastener bonds to metals, glass and medium-to-high surface energy plastics and paint. It will not adhere well to low-surface-energy materials such as polyethylene or polypropylene without special surface preparation. Verify that both mounting surfaces are clean, dry and compatible with acrylic adhesive. The roll measures 50 yards in length for custom cutting.

Replaces screws, rivets and hook-and-loop

The system replaces conventional fasteners like screws, clips, rivets, snaps and bolts where access or repositioning is needed. Type 250 density mates with type 170, 250 or 400 counterparts for adjustable closure strength. The jump is worth it when you need 5X the strength of hook-and-loop with a clear, low-profile engaged thickness of 230 mils.

Questions about this item

What comes in the box and do I need to buy the mating side separately?

One roll of clear Dual Lock SJ3560 Type 250 fastener is supplied, 3/4 in. wide by 50 yds. long. A mating strip of Type 170, 250 or 400 must be purchased separately to create a closure.

Which stem density should I choose for my application?

Type 250 mates with Type 170, 250 or 400; the higher the combined stem count the stronger the closure. Select Type 250 for both sides when you need a balanced, general-purpose hold.

What does the 0.23 inch engaged thickness mean once the fastener is installed?

When two strips are pressed together the mated thickness is 0.23 inches (230 mils), so allow that gap in your panel or door design.
