Brass Fasteners for Marine Industry
Marine environments are among the most corrosive in the world. Saltwater, high humidity, UV exposure and biofouling demand fasteners with proven marine-grade performance. RKIC Group supplies C280 Muntz metal and C260 cartridge brass fasteners — the industry standard for marine hardware — to boat builders and offshore equipment manufacturers worldwide.
Why Brass for Marine Industry?
Saltwater Corrosion Resistance
C280 Muntz metal provides superior resistance to saltwater and marine atmosphere.
Dezincification Resistance
Naval brass (C464) with added tin provides maximum dezincification resistance.
No Galvanic Corrosion
Brass is compatible with GRP, aluminium and timber hull materials.
Biofouling Resistance
Copper-based brass naturally inhibits marine biofouling on underwater fittings.
UV Stability
Brass maintains structural integrity under prolonged UV and ozone exposure.
Proven Track Record
Brass has been used in marine applications for over 150 years.
Marine Industry Applications
Deck Hardware
Deck fittings, cleats, fairleads and stanchion base fasteners.
Hull Fittings
Through-hull fittings, seacock bolts and keel fixing bolts.
Offshore Equipment

Frequently Asked Questions
Which brass grade is best for marine fasteners?
C280 Muntz metal (60% Cu, 40% Zn) is the standard marine brass grade for above-waterline applications. For submerged or severe saltwater exposure, Naval brass (C464 — with 1% tin) provides better dezincification resistance. RKIC Group supplies both grades.
What is dezincification and how does it affect marine fasteners?
Dezincification is a corrosion process where zinc leaches from brass in saltwater, leaving a porous copper structure. It weakens the fastener without visible external damage. Naval brass (C464) and DZR (dezincification resistant) brass prevent this — specify DZR brass for submerged marine applications.
Can brass fasteners be used with aluminium boat fittings?
Brass and aluminium are galvanically incompatible in saltwater — direct contact will cause galvanic corrosion of the aluminium. Use nylon or PTFE isolating washers to separate brass fasteners from aluminium fittings, or specify stainless steel for aluminium boat applications.
