Professional Applications & Engineering Value
This M12 shoulder screw is engineered to address critical alignment and load-bearing challenges in industrial machinery. The 18-8 Stainless Steel material provides inherent corrosion resistance, ideal for washdown environments or outdoor equipment. Its precision shoulder (16 mm diameter, 20 mm length) acts as a built-in spacer, eliminating the need for additional bushings and reducing part count in assemblies like rotating shafts, pulleys, and gears. The hex socket drive allows high-torque installation without damaging the head, while the coarse thread pitch ensures quick assembly and resistance to loosening under vibration. Commonly used in automation, automotive jigs, and conveyor systems, this screw enhances structural integrity and reduces maintenance downtime.
Specification Summary & Compliance
This shoulder screw adheres to ISO 7379 manufacturing standards, with thread dimensions conforming to Class 5g6g tolerance for consistent fit. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring precise alignment. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material restrictions are met for global industrial use.
