How to Use: 1. Drilling Use the drill bit of the size listed in the parameter table of the wire thread insert to drill the hole. Be careful not to drill the hole into a cone shape. The chips generated by the drill hole must be blown out with compressed air. After drilling, the counterbore should not exceed the depth of 0.4 pitch. Too large counterbore is not conducive to the screwing of the wire thread insert. 2. Tapping Use special taps for wire thread inserts to tap. The depth of the tapping must exceed the installation length of the thread inserts. After tapping, use a compressed air spray gun to blow out the debris. When the thread accuracy is high, check the tapped bottom hole with a special bottom hole plug gauge for wire thread inserts. 3. Installation 4. Remove the handle (break off the mounting handle) 5.
