Product Description

The M4*28 Electronic Screws, also known as M4x28 Micro Screws or M4*28 Precision Fasteners, are high-grade fastening components designed for microelectronics and compact assemblies. With a 4mm diameter and 28mm length, these screws excel in securing sensitive modules, circuit boards, and communication interfaces within tight spaces. Manufactured from corrosion-resistant steel, they operate reliably across a temperature range of -40°C to 120°C and withstand industrial environments involving vibration or humidity. Commonly used in robotics, telecom equipment, and automation systems, their ultra-fine threading ensures secure connections for sensors, power units, or display panels. Key advantages include exceptional durability and minimized material fatigue, though precise torque-controlled tools are recommended to avoid over-tightening. These screws comply with ISO 4762 standards, ideal for applications demanding millimeter-level accuracy.
