Tufscrew Security System

Tufscrew Systems replace lag bolts where security is needed. Each system includes Tufnut security nuts, double-threaded Tufscrews, Tufnut washers, and Steel driver nut. 

The Tufscrew is drilled into the wood mounting surface, using the driver nut. After removing the driver nut, you fit the sign over the exposed end of the Tufscrew, then add a washer and secure it with the Tufnuts.
