Torque Calculator

Calculate tightening torque and maximum load for bolts.

Calculate the maximum torque and load for different types of bolts:

BA

BSF

BSW

Metric Coarse

UNC BS970

UNF BS970

UNC ASTM

UNF ASTM

Mach. Screw

The calculated values are the maximum recommended values, based on 90% of yield.

If your bolt is not listed, enter the values of your bolt by hand.
