Default Need a 1/2"-12 threading die - where???

In restoring my Olds I discovered that most of the bolts are 1/2"-12 threads - not the standard (today) 13 threads per inch. Anyone know where I can get a die at reasonable cost? The tool houses I have checked are up around $70 - ouch for one die....

Thanx!

Norm

Norm:
I have both a tap and die in 1/2" X 12. Yes, they are high. If you will pay shipping, I would loan them to you.

Let me know

MSC has them in their catalog for $19.00, the round type.
Online I found them at www.mscdirect.com

Try MSC (Manhatten Industrial Supply) 1-800-645-7270. 1/2-12 die, part #03934122 lists for $18.35, and a plug tap #04843991 is $13.56. They also have taper and bottoming taps. These are imported (usually Poland or Japan)and of good quality. If you want to own a set at reasonable cost, I hope you'll find this helpful.

Get a hex die, not a round one. That way you can use it with a ratchet and deep socket to chase threads on studs. Al Wait

No problem Norm. Would be happy to do it for ya. Mine are "Hanson", and are a bit higher than some to buy, but the crazy thing is that they will sell you one tap for about $44, or two for $24 each!!! The only Die Hanson makes for that size/pitch is a round one. The don't make it in a hex the machine tool place was told by Hanson (or is it spelled Hansen? whatever).
