Key Features & Benefits at a Glance
- Exceptional corrosion resistance with passivated 18-8 stainless steel construction, ideal for harsh or humid environments.
- Superior mechanical strength with 80,000 psi tensile strength and Rockwell B80 hardness for reliable, long-lasting fastening.
- Precise and secure thread engagement thanks to the Class 2A thread fit and UNF fine threads, reducing the risk of stripping or loosening.
- Efficient and flush installation with a standard 82° flat head profile and No. 2 Phillips drive for a clean, countersunk finish.
- Maximum grip and holding power from the fully threaded design, ensuring consistent clamping force along the entire 7/8" length.
- Broad industry compatibility and reliability, manufactured to meet ASME B18.6.3 specifications for consistent quality.
- Safe for regulated applications with compliance to RoHS 3 and REACH environmental standards.
Professional Applications & Engineering Value
This 10-32 UNF flat head screw is engineered to solve critical fastening challenges in demanding industrial settings. The passivated 18-8 stainless steel provides excellent resistance to oxidation and chemical exposure, making it a top choice for marine equipment, food processing machinery, and outdoor enclosures where moisture is a concern. The combination of fine threading (UNF) and a Class 2A thread fit ensures vibration resistance and precise alignment in assemblies, reducing maintenance needs. The flat head with Phillips drive allows for a sleek, flush mount, which is essential for applications where protruding hardware is not an option. With a tensile strength of 80,000 psi, it reliably handles dynamic loads, providing engineers with a durable and compliant machine screw solution for critical mechanical systems.
Specification Summary & Compliance
This screw adheres to Class 2A thread fit tolerances for consistent assembly and is manufactured according to the ASME B18.6.3 standard. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict environmental and safety requirements for hazardous substances.
