BOLT ULTIMATE STRENGTH CALCULATORS

The Calculators below can be to calculate the ultimate (breaking) load of bolts.

This uses the equations from ANSI B1 1-1974 and B18.3.1-1978 which calculates the area carrying the tensile load from the mean of the pitch diameter and the minor diameter.

Results are in Newtons.
