Understated Hardware, Elevated Finish

The soft dome head and muted galvanized sheen bring a quiet sophistication to exposed hardware moments. I love the square-neck detail—it nests into wood for a tailored, seamless look. Use these to secure bench slats or deck accents where the hardware becomes part of the design story. A dependable, polished touch for luxe, lived-in spaces.

Good Plug if you need this model
These are the OEM for Kohler 7000 series I did service on. They needed to be gapped but that’s every spark plug.
