S-94355A731 3/8"-16 x 3/4" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh environments
• Maximum torque transmission through the hex drive design, ensuring secure installation without head interference
• Precise thread engagement with Class 3A fit for reliable, vibration-resistant fastening in critical assemblies
• Enhanced durability from Rockwell B80 hardness, maintaining structural integrity under heavy loads
• Wide industrial compatibility due to UNC coarse threads and flat tip design for consistent seating on shafts and components
• Regulatory compliance assurance meeting ASME B18.3 standards and environmental directives (RoHS 3, REACH)
• Optimized for right-hand applications with standardized 3/8"-16 thread size for seamless integration

Professional Applications & Engineering Value

This 3/8"-16 UNC Class 3A hex headless set screw delivers exceptional engineering value by addressing common industrial fastening challenges. Manufactured from 18-8 stainless steel, it resists oxidation and chemical degradation, making it ideal for machinery, automotive, and outdoor equipment exposed to moisture or corrosive agents. The headless design and flat tip provide flush mounting, preventing protrusion in rotating assemblies while the coarse UNC threads ensure quick installation and high resistance to loosening under vibration. With its hex drive accommodating standard tools, it enables high-torque applications in confined spaces, securing pulleys, gears, and collars with reliable, repeatable performance.

Specification Summary & Compliance

This set screw maintains precise Class 3A thread fit per UNC standards with a diameter of 0.375" and 3/4" length. It conforms to ASME B18.3 manufacturing specifications and demonstrates compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability for global industrial use.
