Professional Applications & Engineering Value

This socket head cap screw with Buna-N sealing technology addresses critical fluid containment challenges in industrial machinery and equipment. The 18-8 stainless steel construction provides excellent corrosion resistance while maintaining 100,000 psi tensile strength, ensuring structural integrity under high mechanical loads. The integrated O-ring creates a positive seal against fluids and gases, making it particularly valuable for hydraulic systems, pneumatic components, and processing equipment where pressure integrity is paramount. The UNC coarse thread design facilitates quick assembly while the Class 3A thread fit guarantees precise engagement, reducing the risk of cross-threading in production environments. This combination of sealing capability and mechanical strength makes it an optimal solution for applications requiring both secure fastening and environmental protection.
