Hi,
I am in the process of rebuilding an all-black 4x5 Anniversary, and I wanted to replace all of the screws with stainless steel.

Thus I was wondering if anyone had a full list of all of the screws and their relevant sizes/heads used in the Anniversary.

Also, I live in the UK, and we have not used Imperial size screws in a long time over here, but more than anything I have no understanding of how the American screw nomenclature works. I know that the machine screw thread in the Anniversary is called a #4, however I have not figured out how to translate this into a BSW, as I gather the UNC threads are compatible with Whitworths, assuming that I might still find some suppliers over here who stock small diameter BSW machine screws.

Thanks in advance,
T

Not exactly as you requested but can help you.

Hi Laurent,
that is rather interesting anyway. I shall try to transcribe and translate what they mean. I am still very unclear as how to translate the hash numbers to something that means something to me.

Cheers,
t

I'll try to scan asap the shematic for help you.

More manuals available at http://www.southbristolviews.com/ graflex manuals link on the left.

Graflex was never very good at listing screw sizes except for the common sizes that could be purchased locally. Specialty screws are only listed as to their function with no clue as to their size if one is missing.

The wood screws are listed as length-diameter-head type.
RH-round head; FH-flat head; oval head-OH.
Machine screws length-diameter/thread pitch-head type, same as wood screws.

Some machinist info:

It is still so terribly complicated. those lists tell me that a #4 has a diameter of 0.112", which is not a measurement that can be converted into a practical fraction, as screws seem to be listed by fractions of inches, but not in 14/125ths... So I gather there will be no joy in me being able to figure out what they mean, and I shall have to order stock from the USA. I do find it daunting that standards would be set at such a level that are impossible to translate.

Thanks for your help though.

The figures are online.

may be of some help.
Skip fractions on the screw number/diameter, convert to mm by multiplying the thousands by 25.4.

Tf, not wishing to question your choices but may I ask why you want to replace the original screws ?

I guess a few reasons. One is that I am missing a couple of the originals, so there are already a few that look a little out of place. Then there is the fact that the originals on the all black body were painted black, so they look pretty ratty now. I am also adding a component to the left side, so I shall be adding some screws. So it just makes sense, in my head, to swap the whole lot for new, and the stainless would be less likely to react with brass/wood/leather, unlike the original screws which rusted and tarnished and often locked or corroded.
