This may seem like a simple question, but it turns out that the answer is not one size fits all. To find the answer to this specific question you’ll need to understand what exactly “head” means in this context. The head of a bolt refers to how far down from the top your threading starts on any given item, and for bolts with heads larger than 1/2 inch (12 mm) typically use an imperial measurement system rather than metric measurements.
The “bolt head size chart” is a tool that allows you to find the bolt head size for any given bolt. The bolt head size is the diameter of the circular part at the top of a screw or bolt.
