What would be the correct reference dimension to show on a drawing for 11 gauge ASTM A-1011 steel?

Thanks David. Do you think a steel screw could possibly gall up with a stainless steel nut?

Thanks 3DDave.

Thanks John.

Dimensionally should a class 3A screw always work with a class 2B nut if they are both made out of steel? If you use anti-seize, should it work if they are both stainless steel?

Thanks, good idea.

Thanks to all of you for sharing your suggestions. We have decided to countersink the back side of the aluminum plate and use flat head screws with nuts. I should have considered this option days ago. Thanks again for all your time and help. Have a great day.

If we disregard galvanic corrosion, is it OK to screw a #8-32 a low strength steel screw into 3/16" thick aluminum sheet? I seem to remember that it is not generally recommended because the aluminum like 5052-H32 is not as hard as a steel screw and that is why we use helicoils. But what about...

Equipment will be 1 1/2 miles from the beach. It needs to last about 15 years. Plates do not need to be electrically bonded.

Situation #1: I have two powder coated steel plates that will be attached with #8-32 screws. There are clearance holes in one plate and threads in the other plate. They will be installed indoors at room temperature in Florida. I am concerned with the high concentration of salt in the moist...

I am working on a very old assembly that has a stainless steel fasteners. I will be working on the equipment and then will be putting in new stainless steel screws and nuts. The notes on the old assembly drawing specified "Apply anti-seize compound GA-9289, Type 2, to threads". I need to work...

I believe the spec that pertains is one that I found shortly after I initiated this question to the web site. I believe ASTM F 1387 Section 8 defines the test to certify that a fittings burst pressure will be at least equal to 4 times the working pressure.

DesertFox I looked thru the attachment you sent and it looks like the fittings are using a 4x safety factor. Thanks for all the info.

I have a stainless steel compression fitting that has a working pressure of 6000 psig. The manufacturer' rep does not know what the relationship is between working pressure and burst pressure. I do not have time for him to research it. Does anyone know what the burst pressure would be? I...

We are thinking of having de-ionized water running through (1/2 inch tube OD) brass compression fittings. The brass is alloy 360 and as such has a zinc content of about 40%. I have heard that if the zinc content in the brass is about 15% or higher, that it has a tendency to leach out of the...
