Heavy-duty mounting squares

3M Scotch 311DC squares are adhesive pads made for permanent bonding on most surfaces. The pack contains forty-eight pre-cut pieces ready for die-cutting and general craft projects. They suit makers who need a strong, immediate hold without liquid glue mess.

Simple press-on installation

Each square applies by peeling the liner and pressing firmly onto the target surface. No tools, curing time or mixing are required. The bond is permanent, so repositioning after contact is not possible and removal will damage delicate materials.

Forty-eight squares per pack

The quantity covers many small embellishments or a few larger panels before a refill is needed. Very heavy or textured objects may exceed the holding power of a single square. Buyers needing removable or reusable fastening should choose a different system.
