  • Length: Brad nails come in various lengths, typically ranging from 5/8 inch (16 mm) to 2 inches (50 mm), although shorter and longer options are available.
  • Head: They feature a small, barely visible head, which is essential for creating a clean and unobtrusive finish.
  • Material: Brad nails are typically made from high-carbon steel for strength and corrosion resistance.
  • Point Type: They often have chisel or wedge-shaped points, allowing for smooth penetration without splitting the wood.
  • Collation: Brad nails are usually collated in a strip or wire configuration, suitable for use in nail guns.

2.3 Common Uses and Applications

18-gauge brad nails are popular for a wide range of applications, including but not limited to:

  • Finish Carpentry: Perfect for attaching trim, moldings, and baseboards, as they leave minimal holes and ensure a clean finish.
