S-92311A624 3/8"-16 x 1" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and extended service life
• Superior holding power and minimal slipping thanks to the cup tip design that bites securely into shafts and components
• Precise and reliable thread engagement ensured by Class 3A fit, providing tighter tolerances for critical assemblies
• High-strength performance with Rockwell B80 hardness, offering excellent resistance to wear and deformation
• Easy installation and removal using a standard 3/16" hex key, facilitated by the headless design for flush mounting
• Robust coarse UNC threads that allow for faster installation and are less prone to cross-threading in industrial settings
• Compliance with major industry standards including ASME B18.3, ensuring consistent quality and interchangeability

Professional Applications & Engineering Value

This 3/8"-16 UNC hex headless set screw is engineered to address common challenges in industrial applications where secure component positioning is critical. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for use in demanding environments such as manufacturing equipment, automotive assemblies, and outdoor machinery. The cup tip design concentrates force on a small contact area, creating a strong bite that prevents shaft or hub movement under high vibration and torque loads. Combined with the Class 3A thread fit and coarse thread spacing, this set screw ensures quick, reliable installation and long-term holding power, reducing maintenance needs and downtime in precision set screw applications.

Specification Summary & Compliance
