Refer to document as below:  Stainless Steel Hexagon Flange Nuts.pdf Stainless Steel Hexagon Flange Nuts --- A hex flange nut is a fastener that incorporates both a hexagonal nut with a flanged or washer-like base, which is a wide area on the bottom of the nut that extends outward past the typical diameter of the nut. Used when a flat washer is not practical, a hex flange nut allows the pressure of the nut to be displaced over a wider area than a plain nut would allow. Most hex flange nut designs are used in locking-type applications, with the flange nut using either a serrated back on the flange or a locking thread within the nut itself to lock the fastener into position when tight.
"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.  |
