Professional Applications & Engineering Value
This M6 metric screw is engineered to address common industrial challenges such as joint loosening from vibration and corrosion in demanding environments. The combination of 18-8 stainless steel and a passivated finish offers exceptional resistance to rust and chemical exposure, making it suitable for machinery, automotive assemblies, and outdoor equipment. The integrated spring lock washer in 410 stainless steel actively counters vibrational forces, maintaining bolt preload and preventing unintentional disassembly. With its fully threaded design and Class 6g thread fit, it ensures consistent clamping force and ease of alignment in repetitive or high-stress applications, reducing maintenance needs and enhancing operational reliability.
Specification Summary & Compliance
This screw adheres to precise dimensional standards, including M6x1mm coarse thread with Class 6g tolerance for reliable fit. Manufactured in compliance with ASME B18.13, it ensures consistent quality and interchangeability. The product is also RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming it is free of hazardous substances and safe for various industrial and international markets.
