Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a technical field of nut, especially a technical field from aligning antidetonation nut.
[ background of the invention ]
The hexagonal nut (Hexagon nut) is matched with the bolt and the screw to be used for connecting and fastening the machine parts. According to different materials, the materials are classified into carbon steel, stainless steel, non-ferrous metals (such as copper) and the like. The working principle of the hexagon nut is that the friction force between the hexagon nut and the bolt is adopted for self-locking. The existing anti-seismic effect is poor, and the anti-seismic anti.
