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 threads with Class 3A fit deliver reliable, vibration-resistant connections, reducing the risk of loosening in high-stress applications. The socket head with hex drive allows for easy installation in confined spaces, while the knurled head enhances torque application without tools slipping. Its high tensile and shear strength ensures durability in dynamic loads, making it ideal for pivots, guides, and rotating assemblies where corrosion resistance and long-term performance are paramount. By integrating robust materials and precise manufacturing, this fastener minimizes maintenance downtime and enhances operational efficiency in industries like aerospace, medical devices, and marine equipment.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a precise Class 3A thread fit for optimal engagement. Dimensions include a 5/16" head diameter, 3/16" thread length, and shoulder tolerances (e.g., diameter: -0.004" to -0.002"). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
