Product 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. Hard and brittle frangible connection may be used for fastening the ceramic material, bakelite, glass and the like. 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.
Installation tool
Tools include: drill bit, wire tap, plug gauge.
Bolt screw sleeve drill bit: When drilling the threaded hole, the drill bit of the plug screw sleeve should be larger than the diameter of the internal thread hole of the plug screw sleeve and smaller than the diameter of the external thread of the plug screw sleeve.
