Sea-Dog 316 Stainless Steel Butt Hinge 1-15/16 Inch, 205142-1, Sold in Pairs

The Sea-Dog 205142-1 is an investment cast 316 stainless steel butt hinge sized for doors, hatches, and lockers aboard boats and in other corrosion-prone environments. Butt hinges consist of two rectangular leaves that attach to the abutting surfaces of a door and door jamb; they are typically mortised into the surrounding wood or fiberglass so the leaves sit flush, then joined together by a hinge pin that lets the door swing freely. Because the leaves and pin are investment cast from 316 stainless steel rather than stamped from lighter-grade alloys, the 205142-1 resists rust and pitting in salt air and washdown conditions far better than standard hardware store hinges, making it a long-term fit for marine cabinetry, companionway doors, and storage compartments.

This hinge measures 1-15/16 inches across the leaf and 15/16 inches wide per leaf, with a 3/16 inch pin diameter, and it opens to a full 1-15/16 inches. It installs with four #10 flat head fasteners (not included), which countersink into the mortise for a clean, low-profile finish once mounted. The 205142-1 is sold as a matched pair, giving you both hinges needed for a single door or hatch in one purchase. Its unfinished silver stainless finish blends with most marine hardware and does not require additional coating.
