Product Description

The M3*30-1 screws, also known as M3-30 machine screws or M3x30mm fasteners, are precision-engineered threaded components designed for robust mechanical fastening in industrial applications. These screws feature a 3mm diameter, 30mm length, and a standard thread pitch, compatible with M3 nuts and threaded inserts. Constructed from high-grade stainless steel, they offer corrosion resistance and a tensile strength of up to 800 MPa, suitable for operating temperatures ranging from -40°C to 250°C. Ideal for electronics, machinery assembly, and automotive sectors, these fasteners enable secure module-to-module connections in compact spaces. Their hex-head design allows tool-free adjustments in compatible systems. While their length provides extended reach for multi-layer component mounting, installation in ultra-thin profiles may require trimming. No integrated electrical or communication interfaces are included, as these screws serve purely structural purposes. Typical applications include securing sensor housings, mounting control panels, and reinforcing enclosure joints in vibration-prone environments.
