S-92196A133 5-40 x 1 1/2" ASME B18.3 18-8 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to 18-8 Stainless Steel construction, ideal for harsh environments and long-term reliability.
• Exceptional mechanical strength with a 70,000 PSI tensile strength and Rockwell B70 hardness, preventing stripping and failure under high stress.
• Precise and secure fastening ensured by the Class 3A thread fit, offering tighter tolerances for vibration-resistant assemblies.
• Optimized for high-torque applications with a standard hex socket head and 3/32" drive, allowing for efficient installation with common tools.
• Versatile partial threading (3/4" min thread length) provides a non-threaded shank for precise clamping and alignment in assemblies.
• Reliable performance in coarse-thread applications with 5-40 UNC right-hand threads, enabling quick assembly and disassembly.
• Compliance with major industry and environmental standards including ASME B18.3, RoHS 3, and REACH, ensuring product safety and regulatory acceptance.

Professional Applications & Engineering Value

This 5-40 UNC Thread Socket Head Cap Screw is engineered from 18-8 Stainless Steel to solve critical challenges in industrial and engineering environments. Its inherent corrosion resistance makes it ideal for applications exposed to moisture, chemicals, or outdoor elements, preventing rust and maintaining integrity. The Class 3A thread fit and coarse UNC thread form provide superior grip and vibration resistance, reducing the risk of loosening in machinery, automotive, and aerospace assemblies. The partially threaded design with a minimum 3/4" thread length allows for precise clamping force distribution, making it perfect for securing components where alignment and shear strength are paramount. The hex socket drive ensures high torque application without slippage, facilitating efficient maintenance and assembly in confined spaces.

Specification Summary & Compliance

This screw features a 5-40 UNC coarse thread with a Class 3A thread fit for high precision. It is manufactured in accordance with ASME B18.3 specifications and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free from hazardous substances and safe for various industrial applications.
