A Clean, Polished Fastener for Seamless Woodwork
The domed head lends a subtle, tailored finish that feels intentional rather than utilitarian. I love how the square neck tucks into timber, keeping the face pristine without extra hardware clutter. Pair these with oiled oak or painted millwork for a crisp, modern-meets-classic detail. A small choice that elevates craft—and the hallmark of refined, livable luxury.
