Product Description

The M3x30 screws, compliant with DIN912 M3x30 standards, are machine screws designed for precision fastening in mechanical assemblies, electronics, automotive, and industrial automation. These hex socket head cap screws feature a 3mm thread diameter and 30mm length, ideal for secure connections between compact components. Constructed from high-grade steel or stainless steel, they offer tensile strengths up to 800 MPa and corrosion resistance via optional coatings like zinc plating. Compatible with standard M3 nuts and threaded inserts, they require a 2.5mm hex key for installation, operating effectively in temperatures from -50°C to +150°C. Advantages include durability, standardized compatibility, and resistance to vibration loosening, though their small size may limit load capacity and demand careful torque control during installation.
