Product Description

The M4.2x20-2# screws, categorized as M4.2-2# fasteners with ISO-compliant threading, are precision M4.2x20 threaded screws optimized for industrial machinery assembly. These zinc-plated steel fasteners feature a 4.2mm diameter and 20mm shaft length, providing 2# thread density for secure component integration in automated production lines. With a tensile strength of 8.8 grade, they withstand operating temperatures from -30°C to +120°C and vibration levels up to 15G. Primarily used in CNC equipment, robotic arms, and power distribution enclosures, these screws enable direct mounting of sensors, control modules, and motor brackets through their anti-corrosive surface treatment. Advantages include uniform torque distribution (recommended 6-8 Nm) and compatibility with M4.2-2# threaded receivers, though requiring specialized drivers for installation. Their compact design supports space-constrained configurations in automotive manufacturing and industrial automation systems.
