Micro screw is a small fastener but a major effect on industry. So micro screw maintenance is an important topic we should pay attention to. Ensure fasteners are more safety used, extend fasteners service life, and improving service performance of the devices, well maintenance do a great contributions in.

When we perform maintenance on micro screw, there are 3 attentive problems should be known:

1. When micro screw has undergone quench treatment, should use silicate cleaner to clean surface impurities. Then rinse carefully to avoid leave any impurities at surface, affect screws normal use.

2. When micro screw after drawing temper, may be the color of it will change. In this case, put screws into diethyl ether for a while, if there separate out some oily substance which shows the fasteners are not much clean than you think. And after analyze can be noticed that there will be a wrong way for stacking screw in drawing temper. Because micro screw have a little oxidation phenomenon in quenching oil. So it’s one of the most noticeable for micro screw maintenance.

3. if there are some whiteness on surface of micro screw, there must be phosphide. The proposed reason for this is that haven’t used the acid cleaner to clean and checked potcher not carefully enough. In a word, cleaning is important in micro screw production process we should pay attention to.

All these above must draw attention to and do all we can do to do well on micro screw maintenance.
