3M Dual Lock Type 250 Reclosable Fastener Black

3M Dual Lock Type 250 Fastener

This black reclosable fastener uses mushroom-shaped stems at a density of 250 per square inch. It engages with a thickness of 230 mils and provides a closure life of 1000 cycles. The polypropylene carrier carries a 300 LSE acrylic adhesive suited for metals, glass, and medium-to-high surface energy plastics and paint. It replaces screws, clips, rivets, or hook and loop where access or repositioning is needed.

50-yard roll with 250 stem density

The roll measures 1 inch wide by 50 yards long for continuous length applications. Type 250 fasteners mate with Type 170, 250, or 400 counterparts, with combined stem numbers determining closure strength. The acrylic adhesive bonds on contact without curing time. Engaged thickness of .23 inches allows consistent alignment in panels, doors, signs, and display components across automotive, electronics, and trade show installations.

For installers needing reusable high-strength bonds

This fastener suits assembly of access panels, cushions, headliners, privacy curtains, and POP displays where repeated opening is required. It is not suited for buyers who need a permanent structural bond, those requiring fastener engagement on low surface energy substrates without primers, or applications demanding a thinner profile than 140 mils carrier thickness. Users needing different stem densities should select Type 170 or Type 400 variants.
