Precisely size clearance holes for your bolts and fasteners using our expert calculator. Avoid costly rework and ensure optimal assembly with correct drilling dimensions. Select your desired fit – close, normal, or loose – and input the nominal bolt diameter to get instant, accurate results for various engineering and DIY projects.
Formula:
Clearance Hole Diameter = Nominal Bolt Diameter + Clearance Tolerance
Where:
- Nominal Bolt Diameter: The standard diameter of your bolt or screw.
- Clearance Tolerance: An added value determined by the desired fit (Close, Normal, or Loose), and unit of measurement.
