Imperial Bolt Sizing

Question

On an imperial bolt, when it says a bolt is 1/2in thats the size of the head right?

And what size is the diameter of the bolt?

What size head would be on a bolt thats diameter is 3/8?

thx

Answer 1

No, that's the diameter of the bolt. The head size depends on the type, slotted, hex, etc.

Above 1/4 inch they are in fractions of an inch, such as 3/8, 1/2, 3/4, 1 inch.

The 1/2 inch number is the size of the clearance hole required.
