Stainless steel hexagonal screw is the most frequently used type of Special stinless steel screw parts. The main function of the external thread it has is to cooperate with the nut. Use this thread connection method to make two parts into one.
Material: sus304 / sus316 stainless steel hexagonal screws currently produced or sold and the standards used include:
Two kinds of half-tooth screws, although they are also half-tooth, are divided into thick rods and thin rods. The thick rod half-tooth refers to the stainless steel screw before the teeth are rubbed, the diameter of the smooth rod is larger than the diameter of the rubbing teeth, we use m8 Screw as an example, the diameter of the polished rod before rubbing teeth is 7.85mm ~ 8.0mm, the diameter of the rubbing teeth is 7.0mm ~ 7.05mm, and the outer diameter of the teeth after rubbing teeth is 7.85mm ~ 9.95mm, which is similar to the diameter of the polished rod. The diameter is on an outer plane; the so-called thin rod half teeth means that the polished rod before rubbing teeth is the diameter of the rubbing teeth 7.0 ~ 7.05, and the outer diameter of the teeth expands to 7.85 ~ 9.95 after rubbing the teeth, while the polished rod part remains unchanged, visually The outer diameter of the upper teeth is thicker than that of the polished rods. 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.
