• Easy installation and removal with a 10mm hex drive and smooth socket head, facilitating quick assembly in confined spaces.
• Consistent thread engagement with Class 4g6g thread fit and M16x2mm coarse pitch, providing reliable fastening and vibration resistance.
• Compliance with international standards including ISO 7379, ensuring interchangeability and quality assurance for global engineering projects.
• Environmentally responsible manufacturing as it is RoHS 3 and REACH compliant, meeting stringent regulatory requirements for industrial safety.

Professional Applications & Engineering Value

This M16 shoulder screw is engineered from high-strength alloy steel to address critical challenges in precision machinery and heavy-duty equipment. The black oxide finish provides a protective layer against rust and wear, making it ideal for applications in automotive assemblies, industrial robots, and conveyor systems where exposure to moisture and friction is common. With a 50mm shoulder length and precise shoulder diameter tolerances, it ensures accurate component alignment, reducing wear and preventing operational failures. The metric coarse threads (2mm pitch) and right-hand thread direction enable quick, secure fastening in dynamic environments, while the hex drive design allows for efficient torque application. By meeting ISO 7379 specifications, this shoulder screw delivers consistent performance, minimizing downtime and enhancing the longevity of mechanical systems in sectors like manufacturing, aerospace, and automation.

Specification Summary & Compliance
