S-92196A947 2-56 x 1 3/4" ASME B18.3, ASTM F837 18-8 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments and reducing maintenance costs.
• High tensile strength of 70,000 psi ensures reliable performance under significant load and stress, minimizing the risk of fastener failure.
• Precise Class 3A thread fit provides superior engagement and vibration resistance, leading to more secure and durable assemblies.
• Hex socket drive (5/64") allows for high torque application and easy installation in confined spaces, improving assembly efficiency.
• Coarse UNC thread enables faster installation and is less prone to clogging in dirty or debris-filled applications.
• Partially threaded design offers an unthreaded shoulder for precise clamping and alignment of components.
• Compliance with major standards including ASME B18.3, RoHS 3, and REACH ensures material quality, safety, and global regulatory acceptance.

Professional Applications & Engineering Value

This Socket Head Cap Screw is engineered to solve critical challenges in machinery, automotive, and electronics assembly. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, which is vital for equipment exposed to moisture or chemicals. The 2-56 UNC coarse thread and Class 3A fit ensure a tight, secure connection that resists loosening under vibration, a common failure point in dynamic systems. The hex drive design allows mechanics to apply high torque with standard tools, speeding up production lines while the partially threaded shank provides a precise bearing surface for accurate component positioning. This combination of features delivers long-term reliability, reduces downtime for maintenance, and is ideal for high-stress industrial fastening applications.
