  • Stainless Steel Hex Socket Cap Screws

    Stainless steel hexagonal screws are the most frequently used type of stainless steel standard parts, and their main function of external threads is to fit with nuts. By using this threaded connection method, the two parts are integrated.


    Material: SUS304/SUS316 stainless steel The current production or sales of stainless steel hexagonal screws and the standards used include:


    Hexagonal head full tooth stainless steel screw DIN933/GB5783/ISO4017/ANSIB18.2/1/JISB1180


    Hexagonal head half tooth stainless steel screw DIN931/GB5782/ISO4014/ANSIB18.21/JISB1180


    Hexagon SUS316 stainless steel screw, thin stem half tooth stainless steel screw GB5784


    The above two types of half tooth screws, although both are half teeth, can be divided into thick and thin rods. The thick rod half tooth refers to stainless steel screws that have a larger polished rod diameter than the polished rod diameter before tooth rubbing. Taking M8 screws as an example, the polished rod diameter before tooth rubbing is 7.85mm~8.0mm, the polished rod diameter is 7.0mm~7.05mm, and the outer diameter of the teeth after tooth rubbing is 7.85mm~9.95mm, which is similar to the polished rod diameter. To the naked eye, the outer diameters of the two appear to be on the same outer plane; The so-called thin rod half tooth refers to the smooth rod with a tooth diameter of 7.0-7.05 before tooth rubbing. After tooth rubbing, the outer diameter expands to 7.85-9.95, while the smooth rod remains unchanged. To the naked eye, the tooth diameter appears thicker than the smooth rod. Of course, we can also conclude that the DIN931 standard stainless steel thick rod half tooth screw is more expensive than the DIN933 stainless steel thin rod half tooth stainless steel screw in terms of cost.
