Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these metric socket head cap screws deliver critical performance where standard fasteners fail. The black-oxide alloy steel construction provides superior corrosion resistance in harsh environments while maintaining Class 12.9 strength characteristics. The M36x4mm coarse thread configuration ensures rapid assembly in structural steel connections, machinery frames, and equipment manufacturing. With partial threading design, engineers gain flexibility in clamping applications while the 54mm head diameter and 27mm hex drive provide substantial bearing surface and torque capability. These socket screws solve vibration-induced loosening problems through precise Class 5g6g thread fit, making them ideal for dynamic load applications in construction equipment, industrial machinery, and automotive manufacturing where reliability is paramount.
