Professional Applications & Engineering Value

This M12 shoulder screw is engineered to solve critical alignment and durability challenges in precision assemblies. The 316 stainless steel material offers exceptional resistance to corrosion and chemicals, making it perfect for industrial machinery, automotive systems, and marine equipment. The black oxide finish not only enhances aesthetic appeal but also provides an extra layer of protection against wear and galling. With a 55mm shoulder length and tight diameter tolerances, it ensures precise positioning of components like bearings, gears, and pulleys, reducing vibration and misalignment issues. The hex drive socket head and knurled texture allow for easy installation in confined spaces, while the coarse metric thread (M12x1.75mm) facilitates quick assembly without compromising strength. Ideal for applications requiring high tensile and shear strength, this screw delivers reliable performance in dynamic and static loads, streamlining maintenance and improving overall system longevity.
