Abstract
An improved pin drive anchor has an elongated body, a lock nut, and a drive pin having a securing section. The outer end of the body is threaded to permit the lock nut to be threadable therein. When the drive pin is driven into the anchor, the security section is designed so that the outer section of the body is expanded, thereby locking the lock nut onto the anchor.
