Clamping Force Calculator

Divide the applied torque by the product of the torque coefficient and bolt diameter to determine the clamping force. The Clamping Force Calculator is a tool designed to compute the force exerted by a bolt when tightened to a specific torque.

This is crucial in various engineering and industrial applications, such as bolted joint design, injection molding, and machinery assembly. Understanding clamping force ensures that joints remain secure without overloading or damaging components. This calculator accounts for torque, bolt diameter, and frictional coefficients to provide accurate force estimates.

Formula:

$F = \frac{T}{K \cdot D}$

Variable	Definition	Units
$F$	Clamping Force	Newtons (N)
