I NEED A EQUIVALENT FOR THE ASTM A-563 GR. A AND GR. B NUTS

[JOHN1978]

Well I think a make a mistake in my last and first question made in this forum group.

I just want to know if the HEX NUTS ASTM A-563 GR. A AND GR. B have an equivalent nut instead of those one.

For example:
the ASTM A-563 GR. DH has an equivalent in ASTM A-194 GR. 2H
both are from the heavy hex nut serie.

That's what i want to know. Because I have a little problem in my local market trying to buy them.

Please if someone has more experience than me in these cases please.
Give me one hand.

This is a material used for NACE MR-0175 Service.

Are you using these nuts in the presence of H2S?


I had a problem purchasing these in Houston for some 3/8-24 x 1" Lg SHCS. I think we purchased ~ 200 for several dollars each.

I was using these in a downhole DST Test String with H2S.

I can get you a name and number if ou are interestted.
