Professional Applications & Engineering Value

This 18-8 stainless steel pan head screw delivers critical performance advantages in demanding applications where corrosion resistance and mechanical reliability are paramount. The combination of UNF fine threading (10-32) and Class 2A thread fit ensures precise engagement in machinery, electronic enclosures, and precision equipment, reducing the risk of vibration-induced loosening. The passivated surface treatment enhances the natural corrosion resistance of stainless steel, making these fully threaded screws ideal for chemical processing, marine environments, and outdoor applications. With dual Phillips/slotted drive options, maintenance personnel benefit from flexible installation methods while the rounded pan head profile provides a finished appearance and eliminates sharp edges in accessible areas.

Specification Summary & Compliance

Manufactured to exacting ASME B18.6.3 specifications, these screws maintain precise dimensional control with Class 2A thread tolerances for consistent performance. The 10-32 UNF fine thread configuration provides superior holding power in materials where coarse threading may compromise integrity. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and material safety. The fully threaded 1½" length and standardized pan head design guarantee interchangeability and reliable performance across industrial applications requiring high-strength stainless steel fasteners.
