Professional Applications & Engineering Value
These M4.5 metric screws with Torx drive and rounded head design address critical industrial fastening challenges. The 18-8 stainless steel construction combined with passivated finish provides exceptional resistance to oxidation and chemical exposure, making them ideal for electronics enclosures, machinery assemblies, and outdoor equipment where corrosion resistance is paramount. The T20 drive system delivers superior torque transfer compared to Phillips or slotted drives, preventing stripping during high-stress installations. With fully threaded M4.5x0.75 mm coarse pitch configuration and Class 4g6g thread fit, these screws ensure rapid assembly and reliable performance in vibration-prone environments, reducing maintenance needs and downtime across manufacturing, automotive, and aerospace applications.
Specification Summary & Compliance
This metric screw features precise M4.5x0.75 mm coarse threads with Class 4g6g tolerance per ISO metric standards. Manufacturing conforms to ASME B18.3.4M specifications for dimensional accuracy and performance. The product is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, ensuring suitability for global industrial supply chains and environmentally conscious operations.
