Professional Applications & Engineering Value
This M12 shoulder screw is engineered to solve critical alignment and pivot point challenges in industrial machinery. The 316 Stainless Steel material offers exceptional resistance to chemicals and saltwater corrosion, making it perfect for marine, chemical processing, and food-grade equipment. The 16mm shoulder diameter acts as a precise bearing surface or spacer, preventing component misalignment and reducing wear in rotating assemblies. Combined with the knurled socket head and 8mm hex drive, it ensures secure, high-torque installation without cam-out, which is vital for maintenance and assembly efficiency. Its Class 5g6g thread fit and coarse thread pitch provide quick assembly and vibration resistance in dynamic applications, from conveyor systems to precision instruments.
Specification Summary & Compliance
This shoulder screw features a Class 5g6g thread fit per metric standards, with a shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm for high dimensional accuracy. It is manufactured in compliance with ISO 7379 for metric shoulder screws and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free of hazardous substances and suitable for global industrial use.
