Gents,

What are the known minimum and maximum measurements for the shoulder to face of a No1 bolt head?

I need to improve the head space; which is currently about 72 thousands of an inch. I would like to get it down to around 64 if possible; or at least better than it is by at least 3 or 4 thou.

The current bolt head measures 0,638 (16,21mm) .

I would like to know if this is at the large or small end of the scale?

And if anyone has what I need; would they be willing to sell?

I'm also in the market for a No4 bolt head at around 0,635" to 0,638"

Thanks in advance, Zed.
