Professional Applications & Engineering Value
This 8-32 UNC thread shoulder screw is engineered to address critical alignment and fastening challenges in precision assemblies. The 316 stainless steel material provides excellent resistance to corrosion and chemical exposure, making it suitable for marine, chemical processing, and outdoor equipment. The black oxide finish not only enhances corrosion protection but also reduces galling during installation. With its coarse UNC threading and Class 3A fit, it ensures quick assembly and high vibration resistance in machinery, pivots, and rotating mechanisms. The knurled socket head allows for secure tool engagement, preventing cam-out in high-torque applications, while the precisely machined shoulder maintains component spacing and reduces wear on moving parts.
Specification Summary & Compliance
This shoulder screw adheres to UNC coarse thread standards with a Class 3A thread fit for precision. Shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005". It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of restricted substances for industrial use.
