M8 stainless steel threaded rod , Iran

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.

In industrial applications, the A2 M8 metric screw is widely used for assembling metal frames, mechanical equipment, electrical panels, and medium-load machinery components. Its uniform thread engagement and high tensile strength allow repeated assembly without thread wear. It is also ideal for aluminum and steel structures, production line machinery, industrial ventilation systems, and light marine installations. Manufactured according to ISO 3506-1 standards, this screw ensures consistent mechanical performance and high operational safety throughout its service life.
