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 Torque Calculator

Calculates the torque needed to clamp a fastener to a target axial force, accounting for thread geometry and friction. Use it when tightening critical bolted joints to avoid under- or over-torquing.
