3M Dual Lock Type 400 Reclosable Fastener
This clear fastener uses mushroom-shaped stems on a polypropylene carrier with an acrylic adhesive backing. It suits makers and technicians who need strong, removable bonds on metals, glass or high-energy plastics without drilling holes.
Replaces screws clips rivets and hook-and-loop
The system engages at .23 inches thick with 400 stems per square inch and a closure life of 1000 cycles. It mates with Type 170 250 or 400 counterparts; combined stem density determines closure strength. The jump is worth it when panels or components need frequent, tool-free access and five times the shear strength of standard hook-and-loop.
Service temperature limit and surface constraints
Operating temperature reaches 200 F, so continuous exposure above that level is not supported. The acrylic adhesive bonds reliably to metals glass and medium-to-high surface energy plastics and paint only; low-energy surfaces such as polyethylene or polypropylene require different preparation or products.

Questions about this item
What width and length of clear backing strip do I need to mount on the surface?
The roll is one inch wide and fifteen feet long, giving a continuous clear polypropylene carrier you can cut to the exact length required for each panel or door.
How do I apply the acrylic adhesive correctly so the stems stay aligned?
Clean the metal, glass or high-energy plastic with isopropyl alcohol, peel the clear polyolefin liner, press the tape firmly for several seconds, then wait the recommended dwell time before engaging the mating side.
When will the mushroom stems lose their grip and need replacing?
The fastener is rated for one thousand closure cycles; after that the stems can deform and closure strength drops, so plan to replace the tape once you approach that cycle count.
