M4.2 screw 25mm
2# series fasteners
M4.2 threaded bolts
M4.2*25-2#
M4.2x25mm screw, 2# series threaded bolt for secure mechanical fastening, compatible with standard M4.2 threaded components. Precision-engineered fastener for industrial assembly or equipment maintenance applications.

Product Description

The M4.2*25-2# is a precision-engineered fastener from the 2# series fasteners, featuring M4.2 threaded bolts with a 25mm length. Designed for industrial applications in machinery, automotive assembly, and structural frameworks, it operates reliably in temperatures ranging from -40°C to +120°C and withstands voltage fluctuations up to 24V DC. This M4.2 screw 25mm variant offers direct compatibility with modular components, enabling secure connections without secondary tools. Its corrosion-resistant coating ensures durability in harsh environments. The fastener supports no integrated input/output interfaces or communication protocols, prioritizing mechanical robustness over electronic integration. Advantages include high tensile strength and vibration resistance, while the absence of embedded sensors or adaptive sizing limits smart functionality. No battery or screen is included. Optimal for fixed installations requiring stable, low-profile fastening solutions.
