M5 A2 stainless steel threaded rod
The A2 stainless steel M5 metric screw has a nominal diameter of 5 millimeters and a standard thread pitch of 0.8 millimeters. It is widely used for fastening medium-load assemblies in machinery, electrical enclosures, and structural frameworks. The screw is available in lengths ranging from 8 to 60 millimeters, allowing precise adaptation to various design requirements. Its tensile strength reaches approximately 500 MPa, while surface hardness varies between 150 and 180 HV. The unit weight is about 0.020 kilograms per 10 centimeters, enabling engineers to calculate total assembly weight and ensure load distribution accuracy in mechanical and structural applications. The fully threaded design ensures secure engagement with nuts and tapped holes, providing consistent load transfer without localized stress concentration.
A2 stainless steel M5 screws offer excellent corrosion resistance, making them suitable for indoor, semi-outdoor, and mildly corrosive industrial environments. The material composition includes approximately 18–20% chromium and 8–10% nickel, which form a passive oxide layer to prevent rust formation. This protective layer remains effective even in humid, coastal, or chemically mild settings, extending the service life of mechanical assemblies. Additionally,
