Professional Applications & Engineering Value

Engineered for demanding industrial applications, this 316 stainless steel socket head cap screw delivers critical performance where corrosion resistance and structural integrity are paramount. The passivated finish significantly enhances protection against chemical exposure and atmospheric corrosion, making it ideal for marine equipment, chemical processing plants, and food processing machinery. The Class 3A thread fit with UNC coarse threads ensures precise mating with tapped holes, reducing the risk of cross-threading while maintaining consistent clamping force in high-vibration environments. The substantial 3/4" hex drive accommodates high torque requirements during installation, preventing tool slippage and ensuring proper preload in critical connections. These socket head cap screws provide reliable fastening solutions for heavy machinery, structural assemblies, and precision equipment where failure is not an option.

Specification Summary & Compliance

This socket head cap screw features inch system measurements with 7/8"-9 UNC coarse threads maintaining Class 3A precision tolerance for superior thread engagement. The fully threaded design spans the entire 2 1/4" length with a standard socket head profile and right-hand thread direction. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring regulatory adherence for industrial applications worldwide.
