Patrick,
I think Brownells also has your 1/4-30 tap for 22.99 US dollars. God only knows what the shipping might be to get across the pond. Here is a link to the HSS tap section. Sombody needed to give my American and your English engineers a whack on the forehead with a slide rule for choosing those thread sizes.....but they sure did a good job on the rest of it

I checked Chuck's MSC and I couldn't find our taps on-line, but I'll bet if you called or got the catalog per Chuck's suggestion, they would have it. They have a ton of stuff.

I agree. The prices seem favorable when I see what a non-metric tap costs here. It is astonishing how many taps & dies one can have, and still not have the right one. Screw thread systems are one of those fields where the world has always been afflicted by the "not invented here" syndrome".

As to MSC versus Brownells, I have observed on several occasions that something that, as an industrial product, can be bought by the gallon without wrecking your budget, suddenly costs the same for a scent-bottle sized flask if it is sold as shooting supplies. And the industrial product is usually precisely labelled, without any snake-oil fantasy as can be found on the "delicatessen" products offered to shooters, model-makers etc.

Oops, this is turning into a rant, better stop now!

Springfield didn't want to pay royalties for patent rights. So they made up their own parts.

Try Kromhard twist drill in Akron OH if they do not have a tap in stock they will make you one. http://www.kromhard.com/

OK to make your own parts, but why on earth invent a new thread diameter/pitch combination? Or did they have underemployed toolmakers? In my "It might come in handy one day" draw - well, actually, it's 360 draws in 3 converted office wall cabinets - I have a Chinese-marked 5.5mm die with 0.9mm pitch. One of those things that you just dare not throw away, otherwise Murphy's Law will cut in and ensure that you need it the very next day!

from the Krag, 1903. Johnson,, and the 1903. all share this screw size. it had nothing to do with Mauser or payin them money..
same thing with the band screws, and butt plate screws,..the didnt change them from the trap door, to the M1 Garand, and trench guns.
the 1917 shares the same screw pitch with the P14....
they didnt change do to they had it in use, with lots of back stock,,if it aint broke dont fix it sort of deal...
but the screw pitch had nothing to do with Mauser....
