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
Compute the tensile load capacity of a metric screw thread based on nominal diameter, pitch, material strength, and safety factor. Use it when verifying bolt joint adequacy in structural or mechanical assemblies.
