Learn how to use the Clearance Holes and Tolerances for Inch Size Fasteners calculator and its working principles

How to Use the Calculator

  1. Enter the diameter of the fastener in inches.
  2. Select the tolerance class (1, 2, or 3).
  3. Click the "Calculate" button to compute the appropriate clearance hole diameter.
  4. The result will be displayed in inches.

Understanding Tolerance Classes

The tolerance class indicates the level of precision required for the fastener and hole fit. Class 1 offers the tightest fit, while Class 3 provides the loosest fit. The tolerance factor is multiplied by the fastener diameter to determine the additional clearance needed.
