• Secure and easy installation with a 10mm hex socket drive and a knurled head for improved grip during tightening.
• Reliable thread engagement provided by the M16x2mm coarse Class 5g6g thread, facilitating quick assembly and disassembly.
• Long, stable bearing surface from the 120mm shoulder length, ideal for supporting rotating parts like pulleys and gears.
• Compliance with international standards including ISO 7379, ensuring consistent quality and interchangeability in global applications.

Professional Applications & Engineering Value

This M16 shoulder screw is engineered to address critical alignment and rotational stability challenges in demanding assemblies. The 316 Stainless Steel material offers exceptional resistance to chemicals and moisture, making it perfect for food processing, marine, and chemical industry equipment where corrosion is a primary concern. The precisely machined 20mm shoulder diameter acts as a built-in spacer or pivot, eliminating the need for additional bushings and reducing assembly complexity. Paired with the Class 5g6g thread fit and coarse 2mm pitch, it ensures robust fastening in high-vibration environments, securing components like linkages, bearings, and conveyor system parts effectively. The knurled head and hex socket drive further enhance installation efficiency, providing a reliable solution for maintenance and production lines.
