Best way to measure iron hosel size

[BigBaffy]

Hi. I need to order a bag of ferrule's for some cast stainless iron heads of different makes and models, but I have no idea how to measure the hosel on the heads. Should they all be .370? How do I know if they need the tapered .355 ferrules?

Please help.

Thanks.

A drill index sizing chart can also be used.

You could also find the specs of the shafts probably online.

Or, take a shaft to the golf store, they will sell you the correct size.

Typically, shafts for Woods are .335

Irons shafts are tapered and parallel .355 and I think .360

Just going off the top of the brain, best to measure or find the spec's online.

Thanks.

I hope this isn't too stupid a question, but do you mean the outside circumference of the hosel, or the inside (where the shaft would go)?

I'm just confused about whether the .370 and .355 refers to the shaft tip size or the size of the hosel on the head.

Male or Female, I guess would be another way of saying it.
