Thread Locking

Delta thread-locking grades are designed to lock and seal threaded fasteners, corrosion and rusting is prevented. Loosening by vibration and shock is eliminated. The use of locking devices becomes obsolete. By Selecting the appropriate grade, users can lock fasteners either permanently, removable or adjustable and have a choice of pre or post assembly applications.
