Barrel Nuts

Barrel nuts, also known as cross dowels, steel cross dowels, or dowel nuts, are cylindrical fasteners with an internal threaded hole running perpendicular to their length. They are designed to be used with bolts, creating a strong and secure joint. Unlike traditional nuts, barrel nuts eliminate the need for machined flanges, offering a lightweight and space-saving fastening solution.

JNZC's barrel nuts are engineered for high-tensile applications, offering robust fastening solutions for industries like aerospace, heavy machinery, and structural engineering. Designed to minimize drilling and eliminate the need for long, expensive bolts, our barrel nuts are ideal for critical tasks such as hanging aircraft engines or attaching wings and tails to fuselages.

Our barrel nuts ensure secure, reliable connections while adhering to strict industry standards or client-specific requirements.
