💡 How to pick the right tap drill diameter for inch mechanical fasteners
You generally match your hole size to the minor diameter target while accounting for material stretch during threading.
- Select decimal equivalents right on the wall mount so you cut faster on busy job sites
- Stick to manufacturer pitch data when working with soft aluminum alloys
- Match the pitch to your specific metal grade for consistent threading performance every time
