S-92196A400 1/2"-20 x 5" 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 environments and reducing maintenance costs.
• High tensile strength of 70,000 psi ensures reliable performance under heavy loads and vibration, minimizing the risk of fastener failure.
• Precise Class 3A thread fit provides excellent engagement and clamping force, leading to more secure and stable assemblies.
• 3/8" hex drive and standard socket head allow for high torque application and easy installation in confined spaces.
• Fine (UNF) thread spacing offers improved vibration resistance and finer adjustment capabilities compared to coarse threads.
• Partially threaded design provides an unthreaded shoulder for precise location and shear resistance in assemblies.
• Compliance with ASME B18.3, RoHS 3, and REACH guarantees consistent quality, safety, and environmental responsibility for global supply chains.

Professional Applications & Engineering Value

This 1/2"-20 UNF Socket Head Cap Screw is engineered to solve critical challenges in demanding industrial applications. The 18-8 Stainless Steel material provides excellent resistance to corrosion and oxidation, making it suitable for machinery, automotive, and marine environments where durability is paramount. The fine thread (UNF) and Class 3A thread fit ensure a tight, secure connection that resists loosening under vibration, a common failure point in dynamic systems. The combination of a high tensile strength of 70,000 psi and a Rockwell B70 hardness means this socket head cap screw can withstand significant stress without deforming, providing long-term reliability and reducing downtime for maintenance and replacements.
