▲ According to different processing materials, refer to the drilling size specifications for pre-drilling processing. When the hardness of the corresponding material is relatively high, please slightly enlarge the bottom hole within the drilling range. ▲ The slotted end of the screw sleeve is downward, and the self-tapping screw sleeve is completely installed into the front end of the tool, which requires vertical contact with the workpiece. When loading (1~2 pitch), please make sure to align with the bottom hole and never tilt. When the tilt is found, do not reverse the tool and re-adjust it before using it. After entering 1/3~1/2, you cannot come again. In addition, do not rotate the tool in reverse direction, otherwise it will cause product failure. ▲ The inner and outer tooth nuts should be at least 1mm lower than the surface of the parts after assembly.
