18-8 Stainless Steel Socket Cap Screw, Plain Finish, Vented, Flat Head, Internal Hex Drive, 1-1/4" Length, Fully Threaded, 1/4"-20 UNC Threads (Pack of 10) Description
Socket Cap Screws are reliable and durable and are used in many applications. They are available in a variety of head styles and materials.
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).
Flat head fasteners are designed to fit flush to the surface when used with countersunk holes. Length is measured from the top of the head. Vented fasteners have been drilled through their entire length to eliminate the possibility of virtual leaks caused by the trapped volume of air at the bottom of blind tapped holes. Hex socket drive systems are driven by hex wrenches or power tools with hexagonal bits.
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. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings.
