Professional Applications & Engineering Value
These M2.5 metric screws are precision-engineered from 18-8 stainless steel to solve critical challenges in compact assemblies. The passivated finish significantly enhances corrosion resistance, making them a reliable choice for electronics, medical devices, and outdoor equipment exposed to moisture and chemicals. The Torx T6 drive and rounded head design prevent tool slippage and damage to sensitive components, ensuring consistent clamping force in high-vibration environments. With a coarse thread pitch of 0.45 mm and Class 4g6g thread fit, they provide rapid installation and robust holding power in plastics and soft metals, reducing assembly time and improving production line efficiency for industrial fastening applications.
Specification Summary & Compliance
This product maintains precise metric dimensions: M2.5 thread size, 0.45 mm pitch, and 5 mm length. Threading conforms to Class 4g6g tolerance for a standard fit. Manufacturing and quality are governed by the ASME B18.3.4M standard. The screws are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming they are free of restricted hazardous substances.
