Professional Applications & Engineering Value

This M3 flat head screw is engineered for precision and resilience in industrial settings. Made from black-oxide alloy steel, it combats corrosion and wear, making it ideal for machinery, automotive, and electronics where exposure to moisture and chemicals is common. The fully threaded coarse pitch design (M3 x 0.5 mm) with a Class 6g thread fit ensures rapid, secure fastening in metals and plastics, reducing assembly time and minimizing loosening risks. The 90° countersink and hex drive allow for flush mounting and high-torque application, solving alignment issues in tight spaces. With a tensile strength of 120,000 psi and Rockwell C32 hardness, it handles dynamic loads effectively, supporting long-term operational integrity in high-strength applications.

Specification Summary & Compliance
