S-92313A434 3/4"-10 x 5/8" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and extended service life.
• Exceptional thread engagement and holding power from the coarse 3/4"-10 UNC thread and precise Class 3A fit, minimizing the risk of loosening.
• Secure and high-torque installation enabled by the 3/8" hex drive, allowing for a reliable and flush headless design.
• Enhanced surface durability and wear resistance thanks to the Rockwell B80 hardness rating.
• Effective component locking provided by the cup tip, which bites into the shaft for a firm, non-slip grip.
• Broad industrial compliance meeting ASME B18.3 specifications, ensuring dimensional reliability and interchangeability.
• Safe for regulated applications with RoHS 3 and REACH compliance, free from hazardous substances.

Professional Applications & Engineering Value

This 316 stainless steel set screw is engineered to solve critical challenges in demanding industrial settings. Its headless design with a 3/8" hex drive provides a secure, flush-mount solution for assemblies where protruding fastener heads are not permissible. The 3/4"-10 UNC coarse thread and Class 3A thread fit ensure rapid installation and a vibration-resistant, high-strength connection, crucial for heavy-duty machinery, power transmission components, and permanent fixturing. The cup tip creates a positive locking action on shafts and collars, preventing axial movement under dynamic loads. Manufactured from 316 stainless steel, it delivers outstanding performance in corrosive environments such as chemical processing, marine applications, and outdoor equipment, significantly reducing maintenance frequency and failure risks.
