Thread Protective Sleeve Model Specification Description: For Example: M3x0.5X1.5D, which means that after the screw set is completed, the female thread is M3, the pitch is 0.5, and the length is 1.5D (length refers to 1.5 times the diameter, that is, 1.5x3=4.5mm ), the length here refers to the length after installation.
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 to blow out the debris. When the thread accuracy is high, check the tapped bottom hole with a special bottom hole plug for wire thread inserts.
3. Installation
Put the wire screw sleeve into the installation wrench (figure 5 on the right), insert the wire screw sleeve installation tail handle into the rod groove of the installation wrench, and turn the handle of the installation wrench to screw the wire screw sleeve into the screw hole. For installation of M14x2 or more phase thread thread inserts, you can use the T type slotting simple tool to install; Note: During the installation and screwing process of the thread
