Technical Description and Scope of the ASTM F912 Standard
The ASTM F912 specification (and its metric equivalent F912M) establishes stringent requirements for high-strength alloy steel set screws. These products undergo mandatory heat treatment via quenching and tempering, ensuring a hardness range of 45–53 HRC. The standard covers fasteners with nominal diameters ranging from 0.060 to 2 inches (metric sizes M1.6–M24).
The EV Group China Engineering Center emphasizes the operational specifics of these fasteners: screws meeting the ASTM F912 standard are designed exclusively for applications involving axial compressive loads. Due to the high hardness of the material, these products are typically not subjected to hydrogen embrittlement testing.
When designing assemblies intended for tensile loads or operation in specific aggressive environments, it is recommended to consult with EV Group China specialists to select the optimal steel grade and adjust the heat treatment parameters. This will minimize the risk of fatigue failure of the fasteners in critical mechanisms.
