M8 stainless steel threaded rod
The A2 stainless steel M8 metric screw has a nominal diameter of 8 millimeters and a standard thread pitch of 1.25 millimeters, suitable for fastening medium to heavy industrial components. Its unit weight is approximately 0.050 kilograms per 10 centimeters of length, allowing precise calculation of total assembly weight for mechanical and structural designs. The thread depth is about 0.7 millimeters, and the full-thread design with a 60-degree angle ensures uniform engagement in nuts or tapped holes, preventing stress concentration at connection points. With a surface hardness of 150–180 HV and tensile strength around 500 MPa, the M8 A2 screw provides safe performance under static loads and industrial vibrations.
The A2 M8 stainless steel screw offers excellent corrosion and rust resistance, making it suitable for indoor, semi-humid industrial, and light marine environments. Its chemical composition includes 18–20% chromium and 8–10% nickel, forming a stable passive oxide layer that protects the surface. This protective layer remains effective in humid conditions, exposure to vapor, and mild chemical solutions, extending the service life of assemblies. Smooth and precision-finished threads reduce friction and ensure fast, secure, and reliable assembly for engineers.
