Stainless Steel AISI 316 Mirror-Polished Boat Cleats | 4Boats

Precision marine cleats manufactured from AISI 316 (marine-grade) stainless steel with a mirror-polished finish for secure mooring on boats, docks and decks. Smooth, rounded horns minimise chafe and provide a reliable mooring point for ropes and fenders.

• AISI 316 (A4) stainless steel for superior corrosion resistance in saltwater and freshwater environments
• Mirror-polished finish for a high-gloss appearance and easy cleaning
• Available in multiple lengths (common sizes: 4 in, 6 in, 8 in, 10 in, 12 in); select the correct length for line control and deck footprint
• Base dimensions, hole spacing and bolt hole diameter vary by SKU—refer to the product page for exact measurements
• Designed for through-bolt installation; use marine-grade A4/316 stainless steel bolts, nuts and washers
• Use isolation washers or dielectric coatings when fastening to dissimilar metals to reduce galvanic corrosion
• Follow fastener manufacturer's torque specifications—hand-tighten then torque to spec; avoid over-torquing
• Robust mooring point suitable for dock, deck and boat applications—verify model-specific load ratings where provided
• Smooth profile to minimise line wear and chafe

Installation and care: fit with appropriate marine-grade fasteners and a compatible marine sealant (eg. marine polysulfide or recommended marine sealant) to prevent water ingress. Rinse with fresh water after use and dry; clean with a non-abrasive stainless cleaner and a soft cloth. Avoid chlorine-based or abrasive cleaners. Use a dedicated stainless polish for long-term finish maintenance. For best corrosion prevention, use A4/316 fasteners and isolation methods when joining dissimilar metals.
