Introduction
The bolt socket is a kind of fitting with great strength. The style of this kind of fitting is quite peculiar, and it looks very much like a closed spring. There are many specifications of bolt sockets, but the main ones circulating in the market are the more common ones. The installation method of the bolt socket is very particular, and some tools are still needed during the installation process.
Feature
Screw bolt advantage sleeve connection condition to improve, and increase the carrying capacity of the threaded connection fatigue strength: using the sleeve-type screw pitch and thread type can eliminate the deviation between the screw holes and the load is evenly distributed, thereby increasing the threaded connection Load capacity and fatigue strength. It can be used for the connection and fastening of hard, brittle and fragile materials such as ceramics, bakelite, and glass. Effectively prevent fragmentation. After using the bolt sleeve, under the same strength condition as the ordinary internal thread, a smaller size and higher strength screw can be selected, so that a large amount of material can be saved, weight and volume can be reduced.

Installation method
1. Drilling hole: The drilling depth should be greater than the
length of the bolt sleeve. Note that the size of the tapping drill
is larger than the usual number.
2. Thread tapping: The size of the tapped thread should correspond
to that of the external thread of the bolt sleeve.
3. Installation: Screw the bolt sleeve into the corresponding
threaded hole, and require the bolt sleeve to be lower than the
surface of the workpiece.
4. Lock key: Use a suitable tool to press the bolt fixing key of
the bolt sleeve into the bottom hole.
