Professional Applications & Engineering Value
Engineered for demanding industrial environments, these 316 stainless steel socket head cap screws deliver exceptional performance where corrosion resistance and mechanical strength are critical. The cold-worked fabrication process enhances grain structure, providing superior resistance to stress corrosion cracking in chemical processing, marine, and food equipment applications. With their UNC coarse thread pattern and Class 3A thread fit, these fasteners ensure rapid installation and reliable clamping force in high-vibration machinery, automotive assemblies, and structural frameworks. The combination of 110,000 psi tensile strength and Rockwell C25 hardness makes these socket head cap screws ideal for applications requiring repeated disassembly without thread wear or galling issues.
Specification Summary & Compliance
These 5/16"-18 UNC socket head cap screws feature precision Class 3A thread fit tolerances and are manufactured to ASME B18.3 dimensional specifications. The fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest international standards for hazardous substance restrictions. All dimensional and mechanical properties adhere to the specified cold-worked fabrication process, maintaining consistent quality and performance across production batches.
