Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and corrosive operational settings. The UNC coarse thread and Class 3A fit deliver reliable clamping force and resistance to loosening under dynamic loads, while the knurled socket head allows for efficient torque transmission without slippage. Its high tensile and shear strength ensures durability in applications like rotating shafts, pivoting mechanisms, and bearing mounts, where alignment accuracy and corrosion resistance are paramount. The shoulder design provides a stable bearing surface, reducing wear and simplifying assembly in industrial equipment and electronic enclosures.
Specification Summary & Compliance
This shoulder screw features an 8-32 UNC thread with Class 3A precision fit, ensuring tight dimensional control and interchangeability. The shoulder diameter and length maintain strict tolerances (e.g., shoulder diameter: -0.004" to -0.002") for consistent performance. Manufactured from 316 stainless steel with a hardness of Rockwell B79, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting use in regulated and environmentally conscious industries.
