Set screws are similar to hexagon bolts, with the exception of being fully threaded instead of an un-threaded shank. They have a six sided head to allow for tightening via a socket wrench or spanner.
Set screws are used in a wide variety of applications, although primarily in the construction industry, steel fabrications, machine building and automotive parts. They are also available in a variety of finishes depending upon the installation environment.
Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high salinity, or poor air-circulation environments. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties or steel and corrosion resistance are required.
