ABSTRACT:
A standard size fastener, such as a nail or screw, is provided with a pointed PVC or similar type material on the fastener tip. The soft end will penetrate wood but not metal materials, such as copper pipe and electrical conduit, when nailing sheathing or sheet rock onto wood framing. The soft front end will squash on impact with metal leaving a rounded blunt shape that will turn or stop when contacting a pipe.
