Attwood recommends using only stainless steel fasteners for stainless steel hardware.

• The cleat stays up when pulled up. Friction springs hold it in place and reduce rattling
• When lowered, cleat is only 1/2" above deck
• Beautiful, strong and durable each stanchion is a 7/8" rod of solid #316 stainless steel
• Backed by a Lifetime Warranty against corrosion-resistance

Installation is simple and quick just drill twice with a 7/8" hole saw. Drainage receptacles (included) capture moisture and send it to the bilge via pitot tubing (not included).
