Basis of Calculation
Carbon steel (density 7.85 g/cm³), GB/T 5782 partially threaded, coarse pitch, base-metal weight (coating excluded). Typical deviation within ±5% for standard parts; stainless 304/316 scale by density 7.93/7.98 (≈ +1.0%/+1.7%). Use measured values for trade settlement.
Matching Nut & Washer Weights
| Hex nut (ISO 4032 / GB/T 6170) M10 | 9.7 g per piece |
| Flat washer (ISO 7089 / GB/T 97.1) M10 | 3.57 g per piece |

FAQ
What nut fits an M10 bolt, and how much does it weigh?
A matching M10 hex nut (ISO 4032 / GB/T 6170) at about 9.7 g per piece; a flat washer (ISO 7089 / GB/T 97.1) runs about 3.57 g per piece.
How much heavier is an M10 bolt in 304/316 stainless, and how much does coating add?
Geometry is unchanged — only the density ratio applies: about ×1.010 for 304 and ×1.017 for 316. Coating is extra: hot-dip galvanizing typically adds 3–6%, electro zinc under 1%; chart weights are base metal without coating.
