Well Nuts consist of a rubber stopper with internal metal threading. This product lengthens the durability and increases the versatility of plastic sign frames. Designed for Plasticade® products including Signicade®, Signicade Deluxe®, Minicade®, and Squarecade®, Well Nuts prevent frame damage when changing sign blanks. Regular screws work on these products, but the process of removing and attaching panels degrades the frame until screws no longer hold securely.

To use Well Nuts and Bolts, drill a 1/2" diameter hole in the sign frame. Insert the well nut. Position sign blank and insert bolt. When tightened, the rubber well nut will expand around hole in the sign blank, providing a secure, damage-free, multi-use attachment.
