Professional Applications & Engineering Value

This 10-32 UNF oval head slotted screw is engineered to address critical challenges in industrial assembly, where corrosion resistance and mechanical integrity are paramount. The 18-8 stainless steel material, combined with a passivated finish, effectively resists oxidation and chemical exposure, making it ideal for applications in marine, food processing, and outdoor equipment. The fine UNF thread and Class 2A fit provide tight tolerances that prevent loosening under vibration, while the fully threaded 1-1/4" length ensures robust clamping force in thin or layered materials. Commonly used in flat head screw applications requiring a smooth surface profile, this fastener supports efficient production lines by reducing maintenance downtime and replacement costs.

Specification Summary & Compliance

The screw adheres to ASME B18.6.3 specifications, with precise Class 2A thread fit and UNF fine thread standards for consistent performance. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for regulated industries. Dimensional accuracy includes an oval head profile with 82° countersink angle and right-hand threading, providing reliable fastening in accordance with industrial norms.
