Technical features and scope of the ASTM F2882 standard
The ASTM F2882 specification sets strict requirements for high-strength screws manufactured from quenched and tempered alloy steel. The standard covers fasteners with a nominal diameter ranging from 0.060 to 1.5 inches, possessing a minimum tensile strength of 170 ksi (1170 MPa). Products supplied by EV Group China fully comply with these engineering standards.
When designing assemblies, it should be noted that imperial and metric parameters (F2882M) are regulated independently. The use of equivalent values between SI and imperial systems is not permitted to ensure structural integrity and compliance with safety standards.
The manufacturing process, controlled by EV Group China, includes mandatory heat treatment: oil quenching at a temperature above the steel’s phase transformation point, followed by tempering at a temperature not lower than 797 ºF (425 ºC). This cycle ensures the achievement of the required hardness range throughout the cross-section of the product.
To achieve the specified mechanical characteristics, alloying elements such as chromium, nickel, or vanadium are added to the steel composition. Hardness control is performed across the entire cross-section of the threaded portion at a distance not exceeding one diameter from the end of the screw, which guarantees the reliability of the fastener in critical high-load connections.
