S-92196A639 3/8"-16 x 3 3/4" ASME B18.3 18-8 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Exceptional mechanical strength with 70,000 PSI tensile strength and Rockwell B70 hardness for reliable load-bearing performance
• Precise thread engagement with Class 3A UNC threads ensuring tight, secure fastening in demanding applications
• Optimized drive efficiency through 5/16" hex socket design providing maximum torque transmission and strip resistance
• Versatile partial threading allowing both secure clamping and smooth shank alignment in assembled components
• Regulatory compliance assurance meeting ASME B18.3 specifications plus RoHS 3 and REACH environmental standards
• Coarse thread advantage enabling rapid installation and reduced cross-threading risks in production environments

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these socket head cap screws deliver critical performance where vibration resistance and structural integrity are paramount. The 18-8 stainless steel composition provides excellent corrosion resistance in manufacturing, automotive, and machinery applications, while the 3/8"-16 UNC Class 3A threads ensure precise fitment in high-tolerance assemblies. The partially threaded design allows the unthreaded shank to bear against mating parts, distributing stress evenly and preventing loosening under dynamic loads. With 70,000 PSI tensile strength and Rockwell B70 hardness, these inch fasteners maintain clamping force in high-stress environments, making them ideal for critical joints in equipment frames, hydraulic systems, and precision machinery where reliability cannot be compromised.

Specification Summary & Compliance

These socket head cap screws feature precision 3/8"-16 UNC Class 3A threads with coarse thread spacing and right-hand thread direction. Manufacturing complies with ASME B18.3 specifications for dimensional accuracy and performance standards. The fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industry requirements for hazardous substance restrictions and chemical safety in industrial applications.
