This is part of it, for sure. They do tend to change part numbers and suppliers so it becomes a guessing game if the part from 10 years ago is the same.
Also want to go on record. Some of this is funny as hell!
Thanks

It really is a bummer. We were able to use them for so long and now its just brutal to go track down manufacturers. But it is what it is. My company did purchase some software that will cross reference McMaster-Carr part numbers to manufacturers. Just not all are listed.
Thanks
Dale
I appreciate the replies, I hesitate to give out too much info about where I work and the whys of the issue. It does make it harder to find parts and place orders. But more or less I'm just whining.
Thanks
Dale
I need manufacturers part numbers not suppliers part numbers. Has to do with DFARS requirements. McMaster does not provide sources from where they buy stuff. McMaster is such a good all around place to find things, looking for the next great site.
Thanks

Looking for an alternative to McMaster-Carr and Grainger. Anyone have some they would like to share. My company no longer allows me to use these guys.

They are being torqued at 120 ft lbs ea on a quantity of 12. Hard to tell when the failure happened, it is just noticed when removing the bolts to remove the unit. The screw seizes then the fight is on to get it out. This has happened 4 times in the process of testing 20 units.

I have a unit that is armor I am bolting down for a vibration test. I have now grade 8 bolts holding it down. One of those lost a thread during diss-assembly and damaged my product. I am hoping that by using a bolt that is softer that I can prevent any damage to my product if a screw decides to...

The carbon steel inserts are stripping out the first few threads. Our test guys use pnumatic tools for installing and removing assemblies and these are tearing up the threads in the inserts. Also there should not be any moisture present during the use of this fixture it is a vibration fixture...

I am having a terriable time locating some C1020 carbon steel plate for a Job. I need 12 pieces .625 x 14.0 x 22.0. My machine shop has tried all his contacts. Even a name and number of a manufacturer would be great to see if there is some sort of shortage. The only problem is that it has to be...
Its a 304 S/S no coating that I know of, I believe its a 14 gage thickness with a brushed finish. These are signs used in subways and on streets in locations around New York.
