In this tutorial we are going to learn about **What is formulas to calculate the hole span for through hole axial components?**

**Standard Tooling**

Metric Formula: Minimum Hole Span = [(Comp Body Length* x 1.112) + 2.36mm] – Lead Dia

Inch Formula: Minimum Hole Span = [(Comp Body Length* x 1.112) + 0.093″] – Lead Dia

**Large Lead Tooling**

Metric Formula: Minimum Hole Span = [(Comp Body Length* x 1.085) + 4.11mm] – Lead Dia

Inch Formula: Minimum Hole Span = [(Comp Body Length* x 1.085) + 0.162″] – Lead Dia

**5mm Tooling**

Metric Formula: Minimum Hole Span = [(Comp Body Length* x 1.109) + 1.40mm] – Lead Dia

Inch Formula: Minimum Hole Span = [(Comp Body Length* x 1.109) + 0.055″] – Lead Dia

**5.5mm Tooling**

Metric Formula: Minimum Hole Span = [(Comp Body Length* x 1.067) + 2.30mm] – Lead Dia

Inch Formula: Minimum Hole Span = [(Comp Body Length* x 1.067) + 0.090″] – Lead Dia
