Professional Applications & Engineering Value
These M3 metric screws with zinc-plated steel construction address critical industrial fastening challenges where corrosion resistance and mechanical reliability are paramount. The coarse 0.5mm pitch threading combined with Class 6h thread fit ensures rapid assembly while maintaining vibration resistance in machinery, electrical enclosures, and automotive components. The narrow rounded head profile provides sufficient bearing surface without requiring excessive clearance, making these slotted drive screws ideal for confined spaces in panel mounting, equipment manufacturing, and precision engineering applications. The fully threaded design delivers consistent clamping force across the entire 20mm length, preventing loosening under dynamic loads.
Specification Summary & Compliance
Manufactured to DIN 84 and ISO 1207 standards with Class 6h thread tolerance for precise metric threading. Features M3 x 0.5mm coarse pitch with right-hand threads and flat tip design. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
