Product Description

The M3-18-7 fastener is a precision M3 screw with an 18mm total length and a 7mm threaded section (M3-0.5 pitch), designed for compact assemblies requiring secure fastening in industrial machinery, electronics, and automation systems. Constructed from corrosion-resistant steel, it offers a tensile strength of 800 MPa and operates reliably in temperatures from -30°C to 150°C. The 7mm thread M3 bolt ensures robust clamping in shallow mounting holes, while its 18mm shank accommodates medium-thickness panels. Ideal for securing sensors, modular components, or enclosures, its hexagonal head supports tool-driven installation. Key advantages include high durability and space-efficient design, though the limited thread length may restrict use in thick materials. Compatible with ISO 4762 standards for M3 screws.
