Product Description

The M4.2*30-2# industrial-grade fastener integrates M4.2x30 screws and M4.2-30 bolts within the 2# series fasteners lineup, designed for robust mechanical applications. These components feature a 4.2mm diameter and 30mm length, compatible with standard torque tools for efficient assembly. Operating reliably across a temperature range of -40°C to +120°C, they excel in automotive, machinery, and construction industries due to high tensile strength (up to 8.8 grade) and corrosion-resistant coatings. The 2# series supports direct integration with modular frameworks via threaded connections, though lacking built-in communication interfaces or electronic components. Limitations include non-adjustable sizing and no battery or screen integration, but their durability and precision alignment make them ideal for structural reinforcement, heavy-load bearing, and vibration-resistant installations. Surface-treated variants enhance resistance to harsh environments.
