Easy 1-2-3 Installation in Metal
E-Z Lok external threads are standard size and pitch to permit use of standard drills and taps. No special tap sizes or installation tools are required. E-Z Lok inserts will not back out or vibrate loose. Immediately upon installation, microencapsulated Loctite® begins to set and the newly installed insert can be fastened to within minutes. In addition, the adhesive seals against liquids and gases to pressures of 6,000 psi, and bonds to virtually all metals. EASY REMOVAL Use a standard screw and bolt extractor to back out a damaged insert and then replace it with a new insert. Removal is simply a matter of overcoming the resistance to torque-out which has been produced by the thread locking material. |
