3M™ Dual Lock™ General Purpose Reclosable Fasteners are a fastening solution that can replace screws, bolts, and rivets. The fasteners contain hundreds of mushroom shaped stems that snap together to form a secure attachment. These are ideal for attaching many frequently removed items such as access doors, signs, displays, and for mounting panels.
