The diameter of the micro screw made by the general factory is 0.8mm, but Suzhou Anzhikou Hardware Technology Co., Ltd. can product the smallest thread diameter is 0.6mm. This kind of precision small screw was mainly used in the bracket connection above the eyeglass frame in the early days. Later, the advent of mobile phones was also used in some places on mobile phone circuit boards. In our usual specifications of the standard, the thread diameter is less than 3 mm, belong to the micro screw series.

Although micro screws are small, but the production is more complicated than conventional screws, because the surface treatment of small screws is very troublesome, not as convenient as large screws, for the surface treatment of small screws, is the need for special electroplating equipment to complete, ordinary galvanizing plant simply can not do it.
For M1.2 small screws, if its length is 5 mm, an ordinary small package can hold hundreds of thousands of them, but the number of hundreds of thousands of them, the general production line can not use so much, but the price of small screws is not high, tens of thousands of ordinary materials of small screws, about one thousand yuan, if you go galvanized, The labor cost of the galvanized plant to start - the value of this screw, so don't look at the small screw is not valuable, but it is very troublesome to operate.

Small screws are small, but the use of the environment is very high-end, mobile phones, computers, precision instruments, etc., the requirements for parts are very high, it is much stricter than the commonly used industrial screws.
The overall quality of precision screws plays an important role in the development of the entire industry, and under the modern management concept, the use of high-precision production techniques is the fundamental basis of the enterprise.
Suzhou Anzhikou Hardware Technology Co., Ltd. is a screw manufacturer with more than 20 years of experience in customized production, which can be customized according to customer's needs to provide you with suitable fastener solutions.
