Professional Applications & Engineering Value
This M12 shoulder screw is engineered from 316 Stainless Steel to combat corrosion in challenging industrial settings, such as marine, chemical processing, and food equipment. The socket head with hex drive allows for efficient tightening in confined spaces, while the knurled texture enhances handling during assembly. Its precision shoulder provides accurate component positioning, reducing wear and misalignment in rotating machinery or pivoting mechanisms. With a coarse thread pitch and high tensile strength, it ensures quick installation and long-term reliability, making it a top choice for engineers seeking durable, ISO 7379 compliant fastening solutions.
Specification Summary & Compliance
This shoulder screw features a Class 5g6g thread fit for precise metric threading, with a shoulder diameter tolerance of -0.072 to -0.01 mm and length tolerance of 0 to 0.25 mm to ensure consistent performance. It complies with ISO 7379 manufacturing standards and is certified RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, adhering to environmental and safety regulations for industrial use.
