The unseen detail that keeps every layer impeccably in place

There’s a quiet luxury in construction that’s done with intention—and cap nails are the kind of detail you never see, but always feel. The square cap head adds a confident, architectural grip that helps materials sit flatter and stay put. Use them wherever you want a more secure hold through membranes and layers, especially on high-exposure exterior assemblies. It’s the small, utilitarian choice that supports a finish that reads effortlessly polished.
