Bolts are a useful device, especially because they have the ability to hold multiple components together. Yet, the serviceability of the bolt, towards any application would be determined by the material used in its construction, the type of bolt, and the specification used. Under specification ASTM F2281, the use of ASTM F2281 Bolts is intended for those applications where the temperature reaches a point of 1800°F.
The dimensions given in the specification for the ASTM SF2281 Hex Bolts include a diameter of 1/4 inches or larger. In addition to the size and the max temperature limit, specified here, the specification calls for the manufacture of ASTM F2281 Hex Cap Screws in either different grades of stainless steel or nickel alloy bolts, with the chemical and the mechanical requirements specified herein. The materials used in the manufacture of astm f2281 flange bolts must also comply with the environmental requirements of the application.
Therefore, the specification also accounts for the use of ASTM F2281M Bolts in various corrosive environments. The ASTM F2281 Studs, along with bolts, hex cap screws, etc are intended for use in applications involving both high temperature and heat resistance.
