Brass Hex Domed Cap Nut

The BRASS HEX DOMED CAP NUT is a decorative and protective threaded fastener integrated with a hexagonal base and smooth hemispherical dome top. It can fully cover exposed bolt ends, avoiding sharp edges while providing reliable threaded fastening and excellent corrosion resistance for humid, water contact and mildly corrosive environments.

Fabricated from solid brass raw material, this acorn nut features inherent rust-proof, acid and alkali resistant performance without extra plating treatment. The natural polished brass surface delivers uniform metallic luster, and brass material has outstanding ductility, easy machining and stable mechanical properties to meet medium load fastening requirements of sanitary and marine equipment.

The standard six-sided hex body matches conventional spanners and sockets for convenient tightening operation. The seamless rounded dome cap fully encloses bolt thread tips, preventing scratch injuries and isolating threads from water, dust and corrosive media to extend service life. Precisely rolled internal threads fit standard metric bolts tightly, supporting repeated disassembly and maintenance operations.

Brass hex domed cap nuts are widely used for plumbing pipeline connection, bathroom sanitary hardware assembly, precision instrument casing fastening, marine metal fittings, furniture decorative connection and all equipment requiring both anti-corrosion performance and neat appearance. Its dual functions of protection and decoration make it a preferred fastener for water and corrosion exposed assembly projects.

We supply full OEM and ODM custom manufacturing services, supporting tailor-made production based on customer technical drawings, physical samples and special dimensional demands. Custom thread sizes, dome height, wall thickness, surface finish (nickel plated, chrome plated) and dedicated export packaging are available to satisfy sanitary, marine and decorative hardware project requirements. Private laser marking and custom brand printing services are also offered for plumbing distributors, sanitary ware manufacturers and marine hardware suppliers.

Each BRASS HEX DOMED CAP NUT is manufactured under strict brass fastener quality control standards. All finished cap nuts pass comprehensive dimensional inspection, thread precision test, surface smoothness sampling test and salt spray anti-corrosion verification before shipment, to guarantee accurate thread tolerance, seamless dome forming and consistent long-term corrosion resistance for every production batch.
