M4 A2 threaded rod , Iran

The A2 stainless steel M4 metric screw has a nominal diameter of 4 millimeters and a thread pitch of 0.7 millimeters, commonly used for fastening light metal and plastic components. Its unit weight is approximately 0.012 kilograms per 10 centimeters of length, enabling engineers to calculate precise load and total assembly weight. Screw lengths range from 6 to 50 millimeters, offering tensile strength of 500 MPa and surface hardness between 150 and 180 HV, providing adequate resistance to static loads and industrial vibrations. The standard A2 stainless steel coating ensures high corrosion resistance, durability in humid environments, and stability against most mild chemical solutions, extending service life in indoor and semi-industrial applications.

From a technical standpoint, the M4 A2 metric screw features a full thread with a 60-degree angle and a 0.7-millimeter depth, ensuring uniform engagement with nuts or tapped components. Uniform hardness along the body and head distributes forces evenly, preventing stress concentration during tightening. Manufactured according to ISO 3506-1 standards, it guarantees mechanical performance and fatigue resistance under cyclic loads. Additionally, the smooth, precision-finished surface reduces friction between threads and nuts, allowing fast and secure assembly in industrial setups.You can order and buy M4 A2 threaded rod from Iran by contacting us through whatsaap and email.
