Professional Applications & Engineering Value

These zinc-plated steel rounded head screws with integrated split lock washers address critical vibration-induced loosening challenges in industrial equipment, machinery assembly, and electronic enclosures. The 10-32 UNF fine thread configuration delivers superior thread engagement in thin materials and precision components, while the Phillips No. 2 drive ensures efficient installation without specialized tools. The combination of 60,000 psi tensile strength and Rockwell B70 hardness provides exceptional resistance to shear forces and fatigue, making these fully threaded screws ideal for applications requiring repeated disassembly and reassembly. The pan head design with standard rounded profile offers optimal clamping force distribution while the zinc plating creates a protective barrier against corrosion in demanding environments.

Specification Summary & Compliance
