Compare calculators

Both calculators run independently — change the inputs on either side to compare results.

Torque Calculator

Calculate the rotational force (torque) produced when a force is applied at a distance from a pivot point. Use it for bolt tightening, lever design, motor sizing, and any mechanical analysis involving rotational force.

Applied Force (N)

Distance from Pivot (m)

Mechanical

Screw Thread Calculator

Determines the clamping force a threaded fastener generates from applied torque, accounting for friction. Essential for engineers and mechanics sizing bolts or designing assemblies where clamping load is critical.
