When you're estimating project costs or planning logistics for bulk orders, knowing the exact nut bolt weight in kg becomes essential. Whether you're dealing with MS bolts, SS bolts, hex nuts, or washers, every kg counts in transport, pricing, and inventory calculations.
This guide provides a detailed nut bolt weight chart in kg per 100 pcs, suitable for fastener dealers, engineering firms, and EPC contractors. It also includes a downloadable PDF chart with values from M6 to M24.
How Nut Bolt Weight is Calculated
The weight depends on the diameter, length, material, and head type. Standard industry estimates are used in logistics and billing.
- Unit of Measurement: kg per 100 pcs (commonly used)
- Material Density: MS = 7.85 g/cm³, SS = 8.0 g/cm³
- Head Type Affects Weight: Hex head weighs more than countersunk
This chart is only for reference based on standard hex bolts and hex nuts made from mild steel.

Weight of Nut Bolt Set (Bolt + Nut)
To calculate the full assembly weight of 1 set (bolt + nut):
Set Weight = Bolt Weight + Matching Nut Weight
Example: For M12 x 60 mm → 10.8 + 3.6 = 14.4 kg/100 sets
