Product Description

The M4*28-2# Screw is a high-strength threaded fastener featuring an M4x28mm shank with precision M4 threading, compliant with 2# grade mechanical performance standards. Designed for robust industrial applications, this M4 Bolt is ideal for securing components in machinery, automotive assemblies, and structural frameworks. It provides reliable torque resistance up to 8.8 N·m and operates effectively within a temperature range of -40°C to +120°C. The 2# Grade M4 Bolt offers corrosion resistance through zinc-plated surface treatment, ensuring durability in harsh environments. Its 28mm length and standardized M4 Threaded Rod dimensions enable compatibility with standard nuts, washers, and mounting holes. Primary advantages include high tensile strength, vibration resistance, and ease of installation, though it requires precise torque calibration to avoid over-tightening. This hardware is widely used in manufacturing, construction, and electrical equipment industries.
