Notes & Limitations

  • Weights are theoretical estimates based on simplified geometric models. Actual weights vary by manufacturer, tolerances, and coating thickness.
  • Hex bolt head dimensions are based on ISO 4014 / DIN 931 nominal values. Hex nut dimensions follow ISO 4032.
  • For nails: weight includes a flat round head (diameter โ‰ˆ 2.5ร— wire diameter). Ring shank, spiral, or headless nails will differ.
  • Coatings (zinc plating, HDG, phosphate) typically add 1โ€“8% to the base steel weight depending on coating thickness.
  • For trade / shipping purposes, always verify with the supplier's actual weight data or mill test reports.
