| Stainless Steel 316 | 7.98 | 102% |
| Brass (C360) | 8.49 | 108% |
| Copper | 8.96 | 114% |
| Aluminum 6061 | 2.70 | 34% |
| Titanium Grade 5 | 4.43 | 56% |
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 2.5ร wire diameter). Ring shank, spiral, or headless nails will differ.
- Coatings (zinc plating, HDG, phosphate) typically add 1โ8% 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.
