Bolt Circle Calculator
Knowing the pole base anchor bolt configuration is important when it comes to determining the bolt circle calculation for light poles. The majority of light poles that we see are square with anchor bolts in the corners. At times, there is an existing pole in place which makes it difficult to measure the corner to corner diagonal. Our calculator will help calculate the bolt circle for square 4-bolt patterns where the only measurement needed is the space between bolts.
Enter the information below to estimate your bolt circle calculation.
