Mechanical
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.

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.
