Professional Applications & Engineering Value
This 18-8 stainless steel socket head cap screw delivers critical performance where corrosion resistance and mechanical strength are paramount. The passivated finish significantly enhances surface durability against chemical exposure and oxidation, while the Class 3A thread fit provides superior vibration resistance in dynamic applications. The partially threaded design offers optimal performance in precision assemblies where the unthreaded portion maintains alignment and increases shear strength. These socket head cap screws are engineered for machinery, aerospace components, and industrial equipment requiring reliable UNRC coarse threads that resist loosening under stress while maintaining 80,000 psi tensile strength for heavy-duty fastening solutions.
Specification Summary & Compliance
Manufactured to precise Class 3A thread fit tolerances with 5/16"-18 UNRC coarse threads and 2" overall length. Complies with MS16995-70, NAS1352C, NASM16995, and Fed. Spec. FF-S-86 standards. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements.
