BOLT TORQUE CALCULATOR
Determine precise tightening specifications for high-tensile fasteners. Accounting for friction factors (K-factors) and proof load utilization for secure industrial assemblies.
✓
Tension Analysis
Verify clamping force (kN) based on applied torque and material property classes.
✓
Surface Factors
Adjust for dry, zinc-plated, or lubricated threads to prevent over-tightening.
