This Standard specifies the mechanical properties of set screws and similar threaded fasteners not under tensile stresses with nominal thread diameters from 1.6 mm up to and including 24 mm, which are made of carbon steel or alloy steel. The mechanical and physical properties apply when tested at an ambient temperature of 10 degree C to 35 degree C and will vary at higher or lower temperatures. This Standard does not apply to set screws requiring special properties such as -- specified tensile stresses; -- weldability; -- corrosion resistance; -- ability to withstand temperatures above +300 degree C or below -50 degree C.
