Stud Bolts Weight Chart

A stud bolt weight chart gives the typical weight of each stud bolt size and assists in determining quick shipment loads, quantities to purchase and material needs. The chart may be in metric or imperial sizes, weights may be recorded in kg/piece and, if necessary, for complete assemblies with nuts. It can be useful to the procurement teams comparing supplier quotations, for EPCs to use for planning materials needs, and freight planners to use for weight estimating and transport cost estimates. The weight may be different depending on the stud bolt specification, its diameter, length, thread configuration and the material grade. This not only allows users to verify the weight matches the required size and quantity, but also enables them to do so without the risk of mistakes when determining total order weight for industrial fastener needs.

How Stud Bolt Weight Is Calculated

Stud bolt weight can be estimated by calculating the cylindrical volume of the stud and multiplying it by the density of the material. For a simplified calculation, the threaded stud is treated as a solid cylinder:

Weight = π/4 × d² × L × ρ

Where:

• d = nominal stud diameter
• L = stud bolt length
• ρ = material density

Example: 3/4″ × 200 mm ASTM A193 B7 Stud Bolt

For a 3/4-inch stud bolt, the nominal diameter is 19.05 mm and the length is 200 mm. Using a steel density of approximately 7.85 g/cm³:

Volume = π/4 × 19.05² × 200 ≈ 57,018 mm³

57,018 mm³ = 57.02 cm³

Therefore:

Weight = 57.02 × 7.85 ≈ 447.6 g or 0.448 kg

This gives an approximate theoretical weight based on cylindrical volume. The actual manufactured weight may differ because the stud has threads, chamfers, and other dimensional features.
