No because they need 80 pcs by the end of this week.

Custom stuff is weeks not days, and the qty price is never good at only 80. . . they probably wouldn't make less than thousands id guess ;D

Or do you mean manufacture by someone other than Unbrako or Holo Crome or some other big maker?

Maybe the local machine shops can work something out with you. Buy something close, have 'em set up a jig and fix 'em up in a jiffy. It'll add to the cost, obviously, but-times are tough-maybe you can find someone to moonlight and do it. Only issue being stainless sucks to machine.


First rule of engineering is to never make what you can buy, but if you can't buy 'em......

I sell to machine shops, and my customer that needs these is one as well.  They'd loose money making these themselves when they can crank out $75 to $500 an hour on their CNC machines ;D

All they machine is stainless and worse.  Actually all their SS is high tensile valve material.  They also work with Titanium, inconel, hastelloy and all the other fun materials.

Cutting tools have really improved over the years, stainless is cake now (for the most part, sometimes there's a little trouble) and those guys are good at it because it's all they do.

[laugh] First rule of Monsterlover is never buy what you can make [laugh]

Set screw with a thinned-down jam nut?

Length isn't an issue if they're tailoring the end anyway.

Second rule of engineering is to not design yourself into a corner where you need an oddball fastener  [roll] (but I digress...).

Funny, I've never done that either.  [laugh]

I've found a strong correlation between boneheaded design/engineering and designers/engineers who aren't personally involved with fabricating, assembling, and maintaining what they create.
If you've had to suffer with what you've botched, it's extra motivation to put in the work on the front end, rather than [bang] at the finish.

Perhaps there's a perfectly good reason for the dilemma the OP is faced with, but it sure smells a lot like designer ADD.

It seems that the thread pitch changed from 3/8-16, which is available readily, to 3/8-24 which is unobtanium.

Current plan is to use 3/8-24 regular head SHCS and turn the head down.  Customer ok'd that this morning.

;D

Also, thruway fasteners no quoted. . .

Definitely. I've seen some pretty stupid things over the years (that I, thankfully, had nothing to do with - but had to fix).....

I think every engineer should be required to build the first unit...

and then repair the first broken one.

I bet things would change. ;D
