    • Construction & Form Works: Provide reliable fastening for temporary and permanent structural supports.


    Why Choose Our Dome Nuts?

    Unlike generic casting nuts, our machined dome nuts offer:


    • Precision T-Threading: Ensures smooth engagement with rock bolt threads, reducing installation time and stripping risks.
    • Corrosion Resistance: Black oxide finish provides a protective layer against moisture and rust in underground environments.
    • Engineered for Load Distribution: The dome shape minimizes stress concentrations, making them ideal for heavy-duty applications where failure is not an option.
