What is a Clearance Hole?

A clearance hole is slightly larger than the bolt diameter, allowing smooth insertion without binding. It ensures proper assembly in mechanical and construction applications.

Why Proper Fit Matters

  • Prevents assembly stress and misalignment
  • Improves structural reliability
  • Ensures easier installation and maintenance

Common Fit Guidelines

  • Close Fit: Minimal clearance for precision assemblies
  • Normal Fit: Standard engineering applications
  • Loose Fit: Easy assembly with more tolerance

Engineering Applications

This tool is widely used in mechanical design, fabrication workshops, construction planning, metalwork, and product assembly where accurate fastener fitting is required.
