Heavy-duty bright steel spike with a smooth round shank, flat head for striking, and a sharp diamond point. The bright (uncoated) finish is intended for general utility work where surface coating is not required - use galvanized or coated spikes for permanent exterior installs that need rust resistance.

• Material: Bright (uncoated) carbon steel
• Head: Flat for striking
• Point: Diamond
• Shank: Smooth round
• Size: 5/16" x 4"

Tip: The 50 Lb contractor box is sized for high-volume framing and form jobs; transfer working quantities to a nail bag rather than carrying the full box on the wall.

Short utility spike for light framing work, formwork bracing, securing thin material to wood, or bulk-pack ground anchoring.
