• Reliable thread engagement with Class 5g6g thread fit, reducing the risk of cross-threading and ensuring consistent fastening.
• Improved grip and tool compatibility from the knurled head and 8mm hex socket drive, allowing for easy installation even in tight spaces.
• Environmental and regulatory compliance with RoHS 3 and REACH, making it suitable for global industrial supply chains.

Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address critical alignment and strength challenges in precision machinery, automotive, and manufacturing equipment. The 316 stainless steel material offers excellent resistance to corrosion and oxidation, which is vital in humid or chemically aggressive settings. The black oxide finish not only enhances aesthetic appeal but also provides an additional layer of protection against rust. With a 16mm shoulder diameter and Class 5g6g thread fit, it ensures precise positioning of components like bearings, pulleys, and gears, reducing vibration and wear. The hex socket drive and knurled head facilitate secure tool engagement, speeding up assembly in confined spaces while maintaining high tensile and shear strength for load-bearing applications.

Specification Summary & Compliance
