- Regulatory compliance meeting ASME B18.3, RoHS 3, and REACH standards for global quality assurance
Professional Applications & Engineering Value
This 5/16"-18 UNC set screw delivers exceptional engineering value in demanding industrial applications where vibration resistance and corrosion protection are critical. The 316 Stainless Steel composition provides superior performance in chemical processing, marine environments, and food processing equipment where moisture and corrosive agents are present. The cup point design creates permanent indentation in shaft components, preventing rotational slippage in power transmission systems, while the Class 3A thread fit ensures precise engagement with mating parts for reliable, long-term fastening solutions. The headless configuration allows for flush mounting in space-constrained assemblies, making it ideal for machinery, automotive components, and precision equipment where secure positioning is paramount.
Specification Summary & Compliance
This high-performance set screw features 5/16"-18 UNC coarse threading with Class 3A thread fit for superior dimensional accuracy and engagement. Manufacturing complies with ASME B18.3 specifications for consistent quality and performance. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety standards for industrial fasteners.
