• Exceptional mechanical strength with 70,000 psi tensile strength and Rockwell B70 hardness for heavy-duty applications
• Precise thread engagement with Class 3A thread fit ensuring reliable fastening in critical assemblies
• Easy installation and removal with standard 3/8" hex drive socket head design requiring minimal clearance
• Versatile partial threading allowing both threaded engagement and smooth shank functionality
• Regulatory compliance assurance meeting RoHS 3 and REACH environmental standards for global applications
• Optimized coarse thread design with 1/2"-13 UNC configuration providing rapid assembly and superior vibration resistance

Professional Applications & Engineering Value

Engineered for demanding industrial environments where chemical exposure and moisture are constant challenges, these 316 stainless steel socket head cap screws deliver unmatched performance. The passivated surface treatment creates an additional protective layer that significantly enhances the natural corrosion resistance of 316 stainless steel, making these fasteners ideal for marine applications, chemical processing equipment, food processing machinery, and offshore installations. The Class 3A thread fit ensures precise tolerance control for critical assemblies where vibration resistance and joint integrity are paramount. With their partially threaded design and coarse UNC thread spacing, these screws provide both secure fastening in threaded sections and smooth bearing surfaces in unthreaded areas, solving common alignment and stress concentration issues in heavy machinery and structural applications.

Specification Summary & Compliance

This socket head cap screw features precision 1/2"-13 UNC coarse threads with Class 3A thread fit per ASME B1.1 standards, ensuring tight tolerances for high-performance applications. The fastener maintains Rockwell B70 hardness and 70,000 psi tensile strength throughout its 2" length with minimum 1½" thread engagement. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental compliance for international industrial use. The inch system measurement, right-hand thread direction, and standard socket head profile provide consistent performance across various assembly requirements.
