3M Dual Lock 250 Reclosable Fastener

This black fastener uses mushroom-shaped stems on a polypropylene carrier with synthetic rubber adhesive. It provides a reusable alternative to screws, clips or hook-and-loop for indoor mounting tasks. Makers and installers can open and close the bond repeatedly without tools. The roll measures 1 inch wide by 10 feet long for custom cut lengths.

Stem density 250 per square inch

The Type 250 stem density determines compatible mating strength with Type 170, 250 or 400 counterparts. Higher combined stem counts yield greater closure force for the application. This specification is the primary factor when selecting the correct fastener pair for a given load requirement. Mismatched densities will not achieve the rated holding performance.

Closure life 1000 cycles

The fastener withstands up to 1000 open-close cycles before stem fatigue reduces grip. Engaged thickness of .23 inches (230 mils) sets the gap between mounted surfaces. Adhesion reaches 224 ounces per inch on stainless steel, suitable for low surface energy plastics and powder-coated metal. Heavy structural loads or permanent outdoor exposure exceed the design limits.

Questions about this item

How much holding force does the 224 ounces-per-inch adhesion deliver when the fastener is mounted in a real application?

The 224 ounces per inch is measured on a stainless-steel test panel; actual holding power on plastics, powder-coated metal or other low-surface-energy substrates will vary with surface preparation and contact area.

The stem density is listed as 250 — what does that cap in practice for mating combinations?

Type 250 stems can mate with type 170, 250 or 400 fasteners; the combined stem count determines closure strength, so pairing with type 400 gives the strongest hold.

With an engaged thickness of 230 mils, what clearance and surface prep does the tape need to mount properly?

The fastener compresses to 0.23 inches when engaged, so allow that gap plus a clean, dry surface; the rubber adhesive bonds best to plastics, powder-coated metal and similar low-energy substrates.
