Professional Applications & Engineering Value
This 3/8"-16 UNC high cap nut delivers exceptional engineering value through its 18-8 stainless steel composition and optimized design. The high cap profile provides increased bearing surface, effectively distributing clamp load and preventing surface damage in assembled components. With coarse UNC threading and Class 2B thread fit, it ensures rapid installation while maintaining precise tolerances for vibration-prone machinery and structural applications. The external hex drive accommodates high-torque applications without stripping, making it ideal for heavy-duty equipment, industrial machinery, and marine environments where corrosion resistance is critical. These industrial cap nuts solve common fastening challenges by combining durability with regulatory compliance for global supply chain requirements.
Specification Summary & Compliance
This high cap nut features precise 3/8"-16 UNC coarse threading with Class 2B thread fit per ASME B1.1 standards, ensuring consistent dimensional accuracy. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental and safety compliance. The inch measurement system and right-hand thread direction provide standardization for North American industrial applications.
