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.

General-purpose construction spike for anchoring concrete forms, securing fence post base plates, staking layout points, or driving through dimensional timber. The 3/8" diameter shank resists bending under heavy hammer blows.
