Screw loosen is one of the main factors of thread connection failure, and there are many ways to avoid it. There are many methods to avoid screw loosen, such as anti-loosening washer, double nuts, coating thread glue etc. Coating thread glue is an important way to solve the problem of screw looseness, and the amount of glue coating is an important factor affect the thread glue process quality. Too much glue coating on screw will lead to waste, insufficient glue coating on screw will lead to the decrease of bonding strength, cannot realize screw anti-loosen. So, thread coating glue quantity need to be controlled in process. As a typical coating glue process, glue dipping has a very wide range of application scenarios. In glue dipping process, the height of coating glue will affect the quantity of coating glue. In this paper, thread coating glue height is studied. The optimal gluing height is obtained through theoretical calculation, and the relationship between coating gluing height and breaking torque of screws is obtained through experimental testing.
