S-92196A734 1/2"-13 x 5 1/2" ASME B18.3 18-8 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel construction for longevity in harsh environments
• Superior load-bearing capability with 70,000 psi tensile strength for demanding industrial applications
• Precise thread engagement through Class 3A fit and UNC coarse threads ensuring secure fastening
• Optimized torque transmission via 3/8" hex drive and standard socket head profile
• Reliable partial threading providing both threaded and unthreaded sections for versatile clamping
• Regulatory compliance assurance meeting ASME B18.3 standards and environmental regulations
• Consistent performance backed by Rockwell B70 hardness for repeated use without deformation

Professional Applications & Engineering Value

This 18-8 stainless steel socket head cap screw addresses critical engineering challenges in heavy machinery, automotive assembly, and industrial equipment where corrosion resistance and high tensile strength are paramount. The 3/8" hex drive combined with UNC coarse threads enables efficient installation in high-vibration environments, while the Class 3A thread fit ensures precise alignment and reduced risk of cross-threading. The partially threaded design allows for optimal clamp load distribution across the 1 3/4" minimum thread length, making it ideal for applications requiring both secure fastening and structural integrity across the 5 1/2" overall length.

Specification Summary & Compliance

Manufactured to ASME B18.3 specifications with Class 3A thread fit tolerance and UNC 1/2"-13 coarse thread spacing. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The inch-system screw features right-hand thread direction and maintains dimensional accuracy across all critical parameters including 0.5" thread diameter and Rockwell B70 hardness certification.
