Professional Applications & Engineering Value
This M8 shoulder screw is engineered to address critical alignment and mounting challenges in precision assemblies. The 316 stainless steel material provides exceptional resistance to corrosion and oxidation, making it suitable for chemical processing, marine hardware, and food-grade equipment where moisture and aggressive substances are present. The 16mm shoulder length and 12mm shoulder diameter with controlled tolerances ensure accurate positioning of moving parts in machinery, reducing wear and preventing misalignment. The hex socket drive allows for high-torque installation in confined spaces, while the knurled head enhances handling during assembly. These features combine to deliver reliable performance in industrial applications requiring long-term durability and minimal maintenance.
Specification Summary & Compliance
This metric shoulder screw features an M8x1.25 coarse thread with Class 5g6g thread fit for standard tolerance applications. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring precise dimensional control. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental and safety standards for industrial components.
