Detailed Technical Parameters of Standard Dog Spikes
| Parameter | Specification / Value | Remarks / Standard |
|---|---|---|
| Standard Size | 5/8" x 5-1/2" (Approx. 16mm x 140mm) | The most common size. Other sizes like 9/16" x 5-1/2" are also used. |

Provides a large striking surface and prevents pull-through. |
| Shank Cross-Section | Square or Rectangular (e.g., 5/8" x 5/8") | The sharp edges cut into the wood fibers, providing superior resistance to loosening compared to a round shank. |
| Point Type | Chisel Point (Pyramidal) | Allows for easier driving into the wood. |
| Weight (per piece) | Approx. 0.45 kg (for 5/8" x 5-1/2") | Varies with size and design. |
