Professional Applications & Engineering Value

These 8-32 UNC rounded head Phillips screws with lock washers deliver critical vibration-resistant fastening solutions for industrial machinery, electrical enclosures, and automotive assemblies. The passivated 18-8 stainless steel construction provides excellent corrosion resistance in humid or chemically aggressive environments, while the integrated 410 stainless steel split lock washers prevent loosening under continuous vibration and thermal cycling. The coarse UNC threading ensures rapid installation and reliable performance in materials where fine threads might strip. With 80,000 psi tensile strength and full threading, these screws maintain structural integrity in high-stress applications, making them ideal for maintenance operations, production lines, and OEM equipment where reliability is paramount.

Specification Summary & Compliance
