Hardware FastenersEnterprises talk about the most "transformation" "Upgrade", however, in the context of transformation and upgrading, the vast majority of Chinese fastener enterprises have to face such a situation: raw material prices rise, labor costs rise.

We can see that the market is full of big or small, or well-known or niche brands. Thousands of brands, on the one hand, means that the hardware industry is developing rapidly, market dividends attract hardware enterprises, on the other hand, it heralds the proliferation of brands, hardware industry development is too bloated, there is no industry planning.

With the continuous development and self-improvement of the hardware industry, the hardware industry in the future may face a "shuffle" revolution, which is the inevitable war. In this campaign, which brands stand, which brands are down, the key factor lies in the hardware enterprises themselves, then hardware enterprises if they want to "shuffle" in the foothold, how to do it?

2, fastener product technical conditions standard. Specifically, it includes the following criteria: fastener Product Tolerance Standard: Provides tolerances and geometric tolerances for product dimensions. Standard for mechanical properties of fastener products: The marking method and mechanical performance items and requirements for the mechanical properties of the product are specified; some fastener products change this content to material properties or work performance content.

① Fastener Product Surface defect Standard: Specifies the type of surface defect and the specific requirements of the product.

② Hardware fastener Product Surface Treatment Standard: Specifies the type of surface treatment and the specific requirements of the product.

③ Hardware Fastener Product Testing standards: set out the above various performance requirements of the testing aspects.
