Finishing nails usually have a small, rounded or countersunk head. Finishing nails are made of Q195 (low carbon steel), Q235 (carbon steel), stainless steel, and are mainly used in carpentry engineering and furniture manufacturing.

The countersunk head provides a smooth surface that can be easily finished or painted over.

Finishing nails differ from common nails in their construction, primarily in the design of their head. Finishing nails have a head that is shaped like a small cylinder, which can be driven flush or slightly below the surface of the wood, making it nearly invisible.

The Finishing steel nails are available in smooth shank and various head types, such as flat smooth head and countersunk checked head. 
Finishing nails can be further customized to meet customer requirements.
