In order to ensure the use of 2h heavy hex nuts, we mainly control the first three items. The appearance and marking can be completed by visual inspection. In order to control the accuracy of the internal thread, it is necessary to make a smooth plug gauge for the inner diameter of the nut. The inspector and the operator can each set a set of standard nuts. Others rely on the manufacturing accuracy of the forming mold and the adjustment of the pressure in the production. Guarantee; and the requirements for mechanical properties depend on raw materials and heat treatment to complete. And we often overlook the most important factor-the cultivation of the quality of workers.
The working principle of the nut is self-locking by the friction between the nut and the bolt. However, the reliability of this self-locking will be reduced in dynamic loads. In some important occasions, we will take some anti-loose measures to ensure the reliability of the nut locking. The use of lock nuts is one of the anti-loosening measures.
Quality is not equal to habit, but habit can see a person’s basic quality, and habit becomes natural. We hear a lot of this sentence. The development of habit is a behavior pattern formed under a certain environment. In fact, it is a subconscious way of behavior. Everyone is an individual with his own personality and habits. Quality training includes; management system, production environment, ideological education, skill training, personal cultivation, etc. This is like a hexagonal nut we produce. The six corners have six edges, and each edge is a factor.
Let our fastener companies not only produce high-quality 2h heavy hex nuts, but also cultivate a group of management talents. This is where the vitality of fastener companies and the improvement of quality lies.
