Technical estimator
Nut blank weight estimator
Estimate an idealized hexagonal blank with a cylindrical bore from its dimensions and material density.
A transparent estimate.
Estimate an idealized hexagonal blank with a cylindrical bore from its dimensions and material density.
This geometric estimate does not model thread volume, chamfers, countersinks, radii, coating, or manufacturing tolerances. It is not a standard nut weight table. For shipping or purchase acceptance, obtain the actual part weight from the team.
Calculation
[(√3 ÷ 2) × across-flats² − π × (bore ÷ 2)²] × height × density × quantity
The default density of 0.283 lb/in³ is an approximate steel value inherited from the published calculator. Enter the actual material density for your estimate.
