self tapping sleeve is also called self tapping sleeve. it has the ability of self tapping thread. it can be directly screwed into a specific hole. after installation, the thread strength is higher and the effect is better. therefore, when the self tapping screw sleeve is installed, the base metal does not need to tap the teeth in advance, and the self tapping screw sleeve can be directly screwed into a specific hole, so as to save the cost.
as the self tapping sleeve has the ability of self tapping, its notch or round hole has the cutting function, so the installation is very convenient. two installation methods are introduced below.
installation method 1 of self tapping screw sleeve: when the installation quantity is small, the simple installation method can be adopted. specifically, the method of bolt
nut of corresponding specification is adopted. the self tapping screw sleeve is fixed on the screw of corresponding model, and fixed with the nut of the same model, so that the three become a whole. then the screw sleeve is screwed into the bottom hole with a wrench, and then the screw is withdrawn.
the second installation method of self tapping screw sleeve: when the installation quantity is large, the special self tapping screw sleeve installation tool can be used. the end of the self tapping screw sleeve installation tool is a hexagonal head, which can be connected with manual tapping wrench, and can also be connected with electric or pneumatic tools.
precautions for installation of self tapping screw sleeve:
1. according to different processing materials, refer to the drilling size specification, carry out pre drilling processing. when the hardness of the corresponding material is high, please slightly increase the bottom hole within the scope of drilling.
2. the slotted end is downward to completely install the self tapping sleeve into the front end of the tool, and the workpiece must be contacted vertically. when loading (1-2 pitch), please make sure that it is aligned with the bottom hole, and never tilt. when the tilt is found, please do not reverse the tool and adjust it again. when it comes to 1 / 3-1 / 2, it is not allowed to start again. in addition, please do not reverse the rotation of the tool, otherwise it will cause product failure.
