S-93445A310 8-32 x 1/8" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Maximum holding power and vibration resistance from the cup point tip design and serrations locking mechanism
• Precise, reliable thread engagement ensured by Class 3A thread fit and UNC coarse thread spacing
• High-strength durability with Rockwell B80 hardness for long-lasting performance under load
• Easy installation in confined spaces using the hex headless design with 5/64" drive
• Guaranteed dimensional accuracy and interchangeability through compliance with ASME B18.3 standards
• Safe for regulated industries with full RoHS 3 and REACH environmental compliance

Professional Applications & Engineering Value

This 8-32 UNC set screw is engineered to solve critical fastening challenges in demanding applications. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, making it suitable for machinery, automotive components, and electronic enclosures exposed to moisture or chemicals. The headless hex drive design allows for flush mounting in tight spaces, while the cup point and serrations create strong bite into shafts and collars, preventing loosening from vibration—a common failure point in rotating assemblies. With its Class 3A thread fit and coarse thread spacing, it ensures quick assembly and reliable clamping force, reducing maintenance downtime and improving operational safety in industrial settings.

Specification Summary & Compliance

This set screw features a right-hand UNC 8-32 thread with Class 3A precision tolerance, 1/8" length, and 5/64" hex drive. It is manufactured in accordance with ASME B18.3 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring both dimensional accuracy and material safety for global industrial use.
