Sea-Dog Smart Cleat 6-1/4 Inch Stud Mount 316 Stainless Steel Boat Cleat

The Sea-Dog Smart Cleat (part number 041666-1) is a stud mount cleat built for clean, secure line tie-off on boats, docks, and marine hardware installations. Constructed of investment cast 316 stainless steel, it resists corrosion from saltwater and marine exposure while holding its polished finish over time. The knob-end design keeps lines from slipping off the horns, reducing the risk of lines working loose and minimizing the potential for collision injuries when moving around deck.

Unlike traditional through-bolt cleats, the Smart Cleat uses hidden stud mount fasteners, so there are no exposed nuts or bolts on the mounting surface to collect water, dirt, or debris. Installation only requires two standard-size bit holes drilled for the studs, with no cutouts or hole saws needed, making it a straightforward upgrade or replacement for an existing cleat base. The studs measure 1/4 inch by 1-1/2 inches with 1/4-20 NC threads, and the cleat ships complete with stainless steel washers and nuts for a full, ready-to-install package.

At 6-1/4 inches long, this cleat suits a wide range of cleating applications where a compact, classic-style tie-off point is needed. Its investment cast construction gives it a solid, one-piece feel that stands up to repeated line loading over years of use.
