Product Description

The M3x8-2# screws, also referred to as M3-8-2# bolts, are precision-engineered 2# grade fasteners designed for secure modular assembly in industrial automation systems. These components enable direct integration with up to 4 input/output modules through a built-in RS-485 communication interface, supporting voltage ranges of 12-24V DC and operating temperatures from -20°C to 80°C. Featuring a corrosion-resistant zinc alloy coating, they are widely used in robotics, CNC machinery, and sensor mounting applications. Key advantages include their 8mm thread length for stable structural connections, compatibility with M3-sized interface ports, and integrated signal shielding for EMI protection. While offering a compact 5mm hexagonal drive head and 8N·m torque capacity, their specialized design limits compatibility with standard fastening tools. The embedded diagnostic LED (2mm x 2mm display) provides real-time connection status monitoring within a 15cm detection range, making them ideal for precision alignment-critical installations.
