Professional Applications & Engineering Value
These 8-32 UNC rounded head Phillips screws provide critical solutions for industrial applications where corrosion resistance and mechanical reliability are paramount. The 18-8 stainless steel material combined with passivated finish creates a robust barrier against oxidation and chemical exposure, making them ideal for automotive assemblies, electronic enclosures, and marine equipment. The fully threaded design ensures maximum holding power across the entire 1/4" length, while the coarse UNC threads and Class 2A fit enable quick installation and superior vibration resistance in high-stress environments. The rounded head profile distributes clamping force evenly, preventing surface damage and maintaining structural integrity in demanding industrial fastening applications.
Specification Summary & Compliance
This screw features precision 8-32 UNC coarse threads with Class 2A thread fit tolerance for consistent engagement. Manufacturing complies with ASME B18.6.3 standards for dimensional accuracy and mechanical properties. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring restricted substance compliance for global markets.
