Stainless Steel 18-8 Hex Nut, MIL-SPEC

Description

Most often used on machine screws and threaded rod, these general purpose nuts are for low-strength assemblies. Hex Nuts have flat tops with chamfered corners; bottoms may be flat or chamfered. Hex drive systems are driven with a wrench.

Stainless steels are used for their corrosion resistance, high-temperature strength, scaling resistance, and low-temperature toughness. These properties account for their extremely wide use in practically every industry. Austenitic Stainless Steels are alloys of iron and carbon that contain between 16% and 30% Chromium, a maximum of 0.15% carbon, along with Nickel (or Manganese), and other alloying elements. The chromium, which helps develop a passive surface oxide film, provides corrosion resistance in stainless steels. Austenitic Stainless Steels are designated by a 3 digit SAE Stainless Steel Grade beginning with the number 3 (e.g. 304, 316). Another common naming convention for Austenitic Stainless Steels are 18/8, 18/10, 18/0, etc. where the 18 refers to the % of Chromium and 8 to % of Nickel contained in the material. Stainless Steel 18-8 denotes 18% chromium and 8% nickel. Stainless Steel 18-8 can be formed and welded. Stainless Steel 18-8 is typically non-magnetic, though the material can become slightly magnetic when cold worked (cold working refers to altering the physical properties of the material without the use of temperature).

A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine.
