What the AI looks for in Finishing Nails
- Corrosion resistance
- Use Type 316 or 304 stainless steel for exterior work, cedar or redwood. Bright steel only for interior work. Plain steel reacts with tannins and leaves black streaks.
- Length
- About three times the thickness of the trim, reaching into framing. Finishing nails have small heads, so their holding power comes from embedment.
- Setting
- Set the head below the surface with a nail set, then fill the hole. The small head is designed to be hidden, not to clamp.
Brands that matter
- Simpson Strong-Tie: Stainless steel nail range.
- Maze Nails: Stainless and galvanized trim nails.
- Hillman: Small packs for interior use.
- Tremont Nail: Cut finish nails for period restoration.
What to avoid
- Bright finishing nails in exterior trim or cedar.
- Driving finishing nails close to board ends without pre-drilling hardwood.
Questions
Finishing nail or casing nail?
Casing nails have a slightly larger, tapered head and hold better for door and window casing. Finishing nails leave a smaller hole.
