3M Dual Lock Reclosable Fasteners are a fastening solution that can replace screws, bolts and rivets. The fasteners contain hundreds of mushroom-shaped stems that audibly "SNAP" together to form a secure attachment with strong adhesive backings that adhere to your substrate. Adjust, realign or reattach with ease, leaving your product with clean, smooth lines free of holes or interruptions. Width: 25mm (1.0inch) Length: 100mm (4.0inch)
