Precision micro screw is also called small screw, different name, but it is the same production.  So where are the micro screws used?  In fact, this is also based on the needs of different use scenarios of customers. Next, follow the steps of small screw manufacturers to understand:  
1. If it is for mobile phones, then when we choose mobile phone micro screws, the appearance is the focus.  Like the screws used for fastening the shell of the mobile phone, the appearance requirements are relatively strict. Even if it is a small micro screw, the screw head will use high-end CD pattern, no scratches in appearance, and bright appearance is the focus of the choice of mobile phone screws.  
2. If it is used on glasses, there will be requirements for micro screws. Glasses screws are generally used for the connection position of glasses frame and glasses frame.  And often swing around the frame, for a long time, if the strength of the miniature screw used on the glasses is not enough, it is easy to fracture, the choice of material is not right, then it is easy to cause the glasses screw slip teeth, so when choosing the glasses screw, it is generally choose carbon steel hardened material.  
3 if it is the miniature screw on the watch, then the precision of the screw should be strictly controlled, watch screws are generally used for inner parts connection fastening, precision is not easy to assemble, so consider the precision of the miniature screw is the focus of the watch.  
In fact, precision micro screws are not only used in the above aspects, like some other electronic and electrical products will also be used.  Suzhou Anzhikou Hardware Technology Co., Ltd. is committed to small screw customization has many years of experience, small specifications can be produced to the outer diameter of 0.6mm screws, according to customer demand to map to sample processing, to provide you with suitable fastener solutions.
