Here is how the Maximum Bolt Spacing equation looks like.

303.5 = 2 \cdot 1.5 + (6 \cdot \frac{100}{2} + 0.5)

303.5m = 2 \cdot 1.5m + (6 \cdot \frac{100m}{2} + 0.5)

303.5 = 2 \cdot 1.5 + (6 \cdot \frac{100}{2} + 0.5)

Maximum Bolt Spacing Solution

Follow our step by step solution on how to calculate Maximum Bolt Spacing?

FIRST Step Consider the formula

b s(max) = 2 \cdot d b + (6 \cdot \frac{t f}{m} + 0.5)

Next Step Substitute values of Variables

∴

b s(max) = 2 \cdot 1.5m + (6 \cdot \frac{100m}{2} + 0.5)

Next Step Prepare to Evaluate

∴

b s(max) = 2 \cdot 1.5 + (6 \cdot \frac{100}{2} + 0.5)

LAST Step Evaluate

∴

b s(max) = 303.5m

How to Evaluate Maximum Bolt Spacing?

Maximum Bolt Spacing evaluator uses Maximum Bolt Spacing = 2*Nominal Bolt Diameter+(6*Thickness of Flange/Gasket Factor+0.5) to evaluate the Maximum Bolt Spacing, Maximum Bolt Spacing is maximum pitch (distance between centres of bolt holes) which is 24 times the thickness of the thinner part, calculated using thickness of the flange is to gasket factor. Maximum Bolt Spacing is denoted by b_s(max) symbol.

How to evaluate Maximum Bolt Spacing using this online evaluator? To use this online evaluator for Maximum Bolt Spacing, enter Nominal Bolt Diameter (d_b), Thickness of Flange (t_f) & Gasket Factor (m) and hit the calculate button.

FAQs on Maximum Bolt Spacing

What is the formula to find Maximum Bolt Spacing?
