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.

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.
