S-92196A725 1/2"-13 x 3 1/4" 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 long-lasting performance in harsh environments.
• Superior torque transmission and strip resistance provided by the 3/8" hex drive and standard socket head profile.
• High-reliability fastening ensured by the Class 3A thread fit, offering precise assembly and vibration resistance.
• Robust mechanical strength with a 70,000 psi tensile strength and Rockwell B70 hardness for heavy-duty applications.
• Wide compatibility and easy installation due to the 1/2"-13 UNC coarse thread and right-hand thread direction.
• Optimized for partial thread engagement where a non-threaded shank is required for specific assembly needs.
• Compliance with major industry standards including ASME B18.3, ensuring consistent quality and interchangeability.

Professional Applications & Engineering Value

This 18-8 Stainless Steel Socket Head Cap Screw is engineered to solve critical challenges in industrial assembly, such as joint failure under high stress and corrosion-induced degradation. The 1/2"-13 UNC coarse thread and Class 3A fit provide excellent engagement in a variety of materials, reducing the risk of cross-threading and ensuring a secure, vibration-resistant connection. The 3/8" hex drive allows for high torque application with common tools, minimizing the chance of driver slippage and head stripping. Its partially threaded design is ideal for applications requiring precise clamp load or where the unthreaded portion must act as a dowel or pivot. Commonly used in machinery, automotive, and heavy equipment, this fastener delivers reliable performance where high tensile strength and environmental durability are non-negotiable.
