The further optimization of the current product structure is an important strategic shift for fastener companies. The transformation of low-carbon steel Hexagonal Nut into A194 2H-grade nuts, which mainly produces medium-carbon steel, will enable enterprises to obtain more profitable space. For this reason, the quality has a higher requirement for the production process and preparation of the nut. Faced with such structural adjustment, what should be done about the quality of the nut? The following Hex Nut Manufacturer will come to tell you where you need to start to develop a quality control plan and inspection specifications.

First, preparation before the output;


Second sampling in the output;


Third, the final inspection after the output.


The preparation before the production includes: the relevant personnel, the condition of the equipment, the equipment of the mold, the craftsmanship, the raw materials, and so on.

However, the first item involves three major aspects: a, mold preparation; b, inspection method; c, manipulation of the production process, resulting in higher requirements for these parts.


First of all, look at the mold preparation: from order to mold planning to production, you need perfect mold equipment. You can think that the production in front is satisfactory, and you don't delay production due to mold. This requires sufficient inventory to ensure this cycle. Generally it is about 20~25 days.


Second inspection method: In this link, we should pay attention to the detection of tools and the detection of methods. The most basic inspection tools we know are vernier calipers, micrometers, thread gauges, Rockwell hardness machines, tensile testing machines, etc. The method of on-site inspection and sampling and sampling that enterprises have always chosen.


Ultimately, the manipulation of the production process: including appearance, method specification, thread stop, mechanical performance. In order to ensure the use of the nut, we first control the first three items, and the appearance can be completed by visual inspection. In order to control the precision of the internal thread, it is necessary to make the inner diameter lubrication plug gauge, one set of inspectors and operators, which can easily check the specification of the nut; other depend on the production precision of the forming mold and the debugging of the sequence pressure in the production to ensure The requirements for mechanical properties depend on the raw materials and heat treatment. And we often neglect the most important factor - the cultivation of the nature of workers.


Everyone is a single person with his own characteristics and habits. The cultivation of the essence includes; the principle of handling things, the environment in which the goods are produced, the ideological education of the operators, the technical proficiency of the operators, and the personal cultivation of the staff. For example, the hex nuts are the same, and the six corners have six edges, each of which is an important element.


Let our fastener companies not only produce high-quality hex nuts, but also other nuts such as Anti Theft Nuts, can also cultivate a group of talents. This is where the fasteners are built and where quality is moving.
