Carbon steel refers to the carbon content of less than 2%, and contains a small amount of silicon Si, manganese Mn, phosphorus P, sulfur S, oxygen O and other impurity elements of iron-carbon alloy, because of its high hardness, strong pressure resistance, strong fatigue resistance, easy processing, superior mechanical properties and other characteristics, often used in the production of building fasteners, to meet the application needs of various construction projects. Yingfeng Txron carbon steel screws have the above mentioned advantages and more "personality", so it is favored by customers.

The following pictures show the common head type (Figure 1), groove type (Figure 2) and drill tail type (Figure 3, Figure 4) of Txron carbon steel screws, which can be customized according to specific requirements.

The quality of the product depends on the fineness of the processing process of the product, and then look at what is special about the processing process of Yingfeng Txron carbon steel screws.
1. Carburizing heat treatment
The carbon steel screw after carburizing heat treatment can remove the residual stress and increase the strength and toughness.
2. Scada coating is used on the surface
Txron screws are usually galvanized, coated and other surface treatment methods;
Txron Sgarda coating can cure zinc layer at room temperature without affecting fastener performance;
Meet the EU RoHS environmental standards, free of heavy metals lead (Pb), cadmium (Cd), mercury (Hg), and hexavalent chromium (Cr6+) and other harmful substances;
The anticorrosion grade reaches the Australian standard C4 level.
3.1500H high salt spray + acid rain test
Salt spray test 1500H and sulfur dioxide gas corrosion test (acid rain test) 25 cycles to ensure that our screws have high corrosion resistance and long service life;
Has obtained the third party SGS international certification.
Room temperature treatment, no high temperature tempering, screw strength does not decrease;
24H/48H hydrogen embrittleness test to ensure that our screws will not break easily.
