- Durable Rockwell B79 hardness offers excellent wear resistance, extending service life in repetitive industrial applications.
Professional Applications & Engineering Value
This 316 Stainless Steel shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and corrosive environments. The UNC coarse threading and Class 3A fit ensure rapid assembly with high vibration resistance, reducing maintenance needs in conveyor systems, robotic arms, and electronic enclosures. The knurled head and hex socket drive facilitate secure tool engagement, minimizing installation errors. With its corrosion-resistant properties, it excels in chemical processing, marine hardware, and food-grade equipment, providing long-term reliability where moisture and aggressive substances are present. The precise shoulder diameter and length allow for accurate alignment in pivoting mechanisms, enhancing operational stability and reducing part wear.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A precision fit for tight tolerances. Dimensions include a 5/16" head diameter, 3/16" thread length, and 1 1/8" shoulder length with tight tolerances (e.g., shoulder diameter: -0.004" to -0.002"). It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use.
