Fastener Weight Calculator
Estimate the weight per piece and per 1,000 pieces (or any quantity) for common fastener types — bolts, nuts, washers, nails, and screws. Based on theoretical volume × material density. Essential for purchasing, shipping cost estimation, and inventory management.

| 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 ≈ 2.5× wire diameter). Ring shank, spiral, or headless nails will differ.
- Coatings (zinc plating, HDG, phosphate) typically add 1–8% 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.
