Professional Applications & Engineering Value

Engineered for industrial assembly and equipment manufacturing, these zinc-plated steel screws address critical fastening challenges. The fully threaded UNC coarse design delivers maximum thread engagement in soft metals and plastics, preventing loosening from vibration. With 60,000 psi tensile strength and Rockwell B70 hardness, they maintain structural integrity in high-stress applications while the Phillips pan head provides a balanced combination of driving torque and low-profile installation. The zinc plating offers essential corrosion protection for machinery, electrical enclosures, and automotive components exposed to moderate environmental conditions.

Specification Summary & Compliance
