Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and reducing replacement frequency.
- High mechanical strength with 80,000 psi tensile strength and Rockwell B85 hardness for reliable performance under heavy loads.
- Secure and flush installation thanks to the flanged button head design, which eliminates the need for a separate washer and provides a wider bearing surface.
- Easy assembly and disassembly with a 1/8" hex drive, allowing for efficient torque application in confined spaces.
- Precise thread engagement with a Class 2A fit and 10-32 UNF fine thread, ensuring vibration resistance and a secure hold.
- Full thread length for maximum grip and adjustability along the entire 1/2" shank.
- Compliance with environmental regulations including RoHS 3 and REACH, ensuring safety and suitability for global markets.
Professional Applications & Engineering Value
This 10-32 UNF flanged screw is engineered to solve critical challenges in industrial assembly. The 18-8 Stainless Steel material offers excellent resistance to rust and corrosion, making it perfect for applications in marine, chemical processing, and outdoor equipment where environmental factors degrade lesser materials. The combination of a rounded button head and integral flange distributes clamping force effectively, preventing surface damage and loosening under vibration—common in machinery, automotive, and electronics enclosures. Its fine threading and Class 2A thread fit provide superior holding power in tapped holes, reducing the risk of strip-out and ensuring long-term joint integrity. The hex drive facilitates quick installation with standard tools, streamlining production lines and maintenance workflows.
Specification Summary & Compliance
This screw features a 10-32 UNF fine thread with a Class 2A tolerance for consistent fit. Key dimensions include a 1/2" length, 0.75" flange diameter, and 1/8" hex drive. It is manufactured from 18-8 Stainless Steel and is fully threaded. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for use in regulated industries.
