Professional Applications & Engineering Value

This M2 shoulder screw is engineered to solve critical alignment and spacing challenges in precision assemblies. The 316 stainless steel material provides exceptional resistance to corrosion and oxidation, making it suitable for medical devices, marine equipment, and food processing machinery where moisture and chemicals are present. The 45mm shoulder length acts as a precise axle or pivot, eliminating the need for additional spacers and reducing component count. Combined with the hex socket drive and knurled head, it ensures vibration-resistant fastening in compact spaces. Its right-hand coarse thread and Class 5g6g thread fit facilitate rapid installation while maintaining positional accuracy in automated production lines, ultimately enhancing assembly efficiency and product lifespan.
