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.

AISI 316 stainless steel threaded rod

AISI 316 stainless steel threaded rod is one of the most widely used fasteners in marine, chemical, and food industries due to its unique chemical composition and high resistance. This alloy contains approximately 16–18% chromium, 10–14% nickel, and 2–3% molybdenum, which ensures stability against chloride-induced corrosion. The tensile strength of AISI 316 threaded rod is typically in the range of 515–700 MPa, while its yield strength is about 205 MPa. The standard working temperature range for this alloy is from -50 to 870 °C, providing long-term performance in acidic or humid environments.

Dimensionally, AISI 316 stainless steel threaded rods are produced in sizes from M3 to M36 with lengths ranging from 100 to 3000 mm, and threads are manufactured according to ISO 965 tolerance class 6g. The surface hardness of this alloy generally falls between 79 and 95 Brinell, which is equivalent to approximately 20–25 Rockwell C. Its salt spray test resistance exceeds 1000 hours without rust formation, making it ideal for marine environments. Using AISI 316 threaded rods increases structural lifespan and reduces maintenance costs in critical systems.

stainless steel threaded rod

Stainless steel threaded rods are available in low diameters with 1 meter length and sometimes in higher diameters up to 3 meters of length. both grades of 304 and 316 of stainless steel threaded rod are available that both have equal mechanical properties however Grade 316 has better resistance against corrosive materials. due to the lower tensile strength of stainless steel compared to carbon steel in most cases Coarse threads are used on the surface of stainless steel threaded rods.
