Product Description

The M4x20-2# Screw Fastener is a premium-grade M4 Threaded Bolt 2# component designed for robust mechanical fastening applications. Featuring M4 diameter and 20mm length, this fastener is crafted from corrosion-resistant steel with a tensile strength of 8.8 grade, ensuring durability in harsh environments. Operating within a temperature range of -30°C to +120°C, it supports secure modular assembly in industries like automotive, electronics, and machinery manufacturing. Part of the 2# Series Fastener Kit, it integrates seamlessly with standard M4-compatible nuts and mounting plates. Key advantages include high vibration resistance and easy installation using hex keys; however, it requires precise torque control to avoid over-tightening. Ideal for structural joints requiring high shear strength and reliability.
