Refer to document as below:  Stainless Steel Hexagon Socket Set Screws.pdf Stainless Steel Hexagon Socket Set Screws is screw fastening principle, most use between shaft and sleeve to prevent shaft and sleeve in use process to change position of the fasteners. Can be used to prevent the relative movement between the shaft and shaft sleeve, also some occasions Hexagon Socket Set Screws used to disassemble, cooperate closely, such as two parts can be rely on top of silk to separate.
Commonly used in mining, metallurgy, textile, conveying machinery, etc. Priority is suitable for the required equipment and parts of simple, has a certain adjustable mind, easy to install, has a dual structure of sealing device, can work under harsh environment. A variety of forms structure, good versatility and interchangeability. "Stainless Steel" - With the addition of 12% chromium to iron, stainless steel is formed. The chromium protects the iron against most corrosion or red colored rust; thus the term "stainless steel". The ability of stainless to form a thin layer of protection on its outside surface, called a "passive film", is its most important characteristic in preventing corrosion.
"18-8" - 300 series stainless steel having approximately (not exactly) 18% chromium and 8% nickel. The term "18-8" is used interchangeably to characterize fasteners made of 302,302HQ,303,304,384, XM7, and other variables of these grades with close chemical compositions. There is little overall difference in corrosion resistance among the 18-8 types, but slight differences in chemical composition do make certain grades more resistant than others against particular chemicals or atmospheres.
Austentic - Refers to 300 series stainless, the most popular of the stainless alloys accounting for 85%-90% of stainless fasteners sold Named for sir Robert Williams Austen, an English metallurgist, austentic stainless is a crystal structure formed by heating steel, chromium, and nickel to a high temperature where it forms the characteristics of 300 series stainless steel.
