Professional Applications & Engineering Value
This 316 stainless steel rounded head screw delivers exceptional value in corrosive or chemically aggressive environments where fastener integrity is critical. The combination of 70,000 psi tensile strength and Class 3A thread fit provides reliable performance in vibration-prone applications across industrial machinery, marine equipment, and chemical processing systems. The passivated finish enhances the natural corrosion resistance of 316 stainless steel, while the hex drive and coarse UNC threading enable quick installation in aluminum, plastics, and softer alloys. Engineered to ASME B18.3 specifications, these fully threaded screws maintain dimensional consistency for predictable performance in high-volume manufacturing and maintenance operations.
Specification Summary & Compliance
This fastener features precision 6-32 UNC coarse threads with Class 3A fit for superior thread engagement. Manufacturing complies with ASME B18.3 standards ensuring dimensional accuracy and interchangeability. The screw is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making it suitable for regulated industries and international markets. With complete threading along the 5/16" length and consistent Rockwell B55 hardness, this screw delivers reliable performance across its specified applications.
