Professional Applications & Engineering Value
Engineered for demanding precision applications, this socket head cap nut combines 18-8 stainless steel material integrity with UNF fine threading to solve common industrial fastening challenges. The corrosion-resistant properties prevent degradation in moist or chemical environments, while the Class 2B thread fit and partial threading design minimize the risk of cross-threading and ensure consistent clamping force. Ideal for machinery, automotive, and aerospace assemblies where vibration resistance and reliable performance are critical, this nut's hex drive and specified 0.831" hole diameter facilitate easy installation in confined spaces, reducing assembly time and improving operational efficiency.
Specification Summary & Compliance
This socket nut adheres to UNF thread standards with a 1/2"-20 fine thread and Class 2B thread fit for consistent dimensional accuracy. It meets REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) compliance requirements, ensuring environmental and safety standards are upheld. Key specifications include a 0.8" OD, 0.84" height, and 0.45" thread depth, manufactured to provide reliable performance in industrial fastener applications.
