S-94355A148 6-32 x 1/2" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and extended service life.
• Exceptional holding power and thread engagement ensured by the Class 3A thread fit, minimizing the risk of loosening under vibration.
• High-strength durability with a Rockwell B80 hardness, providing reliable performance in demanding applications.
• Secure and flush installation thanks to the headless design and flat tip, perfect for applications where a protruding head is not acceptable.
• Easy installation and removal with the 1/16" hex drive, allowing for efficient assembly and maintenance with standard tools.
• Reliable fastening in coarse-thread applications due to the UNC thread form and coarse thread spacing, offering quick assembly and strong holding in softer materials.
• Broad industrial compliance meeting ASME B18.3, RoHS 3, and REACH standards, ensuring quality, safety, and environmental responsibility.

Professional Applications & Engineering Value

This 6-32 UNC set screw is engineered to address critical challenges in industrial assembly, such as component slippage and corrosion-induced failure. Manufactured from 18-8 Stainless Steel, it provides excellent resistance to rust and oxidation, making it suitable for applications in machinery, automotive, and electronics exposed to moisture or chemicals. The Class 3A thread fit and coarse thread spacing ensure a tight, secure fit that maintains position under dynamic loads and vibration, reducing maintenance needs. The headless design and 1/16" hex drive allow for a clean, flush installation in confined spaces, while the flat tip offers concentrated clamping force without damaging shaft surfaces. Ideal for securing collars, gears, and pulleys, this screw delivers reliable, long-term performance in precision engineering contexts.
