Product Description

The M4 machine screw (also referred to as M4-30-2# bolt or Metric screw M4x30) is a precision-engineered fastener designed for robust mechanical connections in industrial applications such as automation systems, machinery assembly, and electronic equipment enclosures. With a diameter of 4mm, length of 30mm, and 2# thread pitch, it complies with ISO 4762 standards for dimensional accuracy. Constructed from high-grade stainless steel or carbon steel with optional coatings for corrosion resistance, this screw operates reliably in temperatures ranging from -30°C to +120°C and can withstand vibration and moderate electrical loads. Key advantages include durability, compatibility with standard M4 nuts, and ease of integration into modular systems. A potential limitation is the need for precise torque control during installation to prevent stripping. Widely used in sectors requiring metric hardware, it ensures secure fastening for panels, brackets, and structural components.
