Well...
I use screws in my job. Lots, and lots, and lots of screws.
Several weeks ago, I contacted my supplier because I was running low, and needed to restock.
Now, I'm very particular about my screws...and so are my customers, so I requested samples which I could approve or refuse, because I had gotten funky screws from people before.
I have leanred that a screw is NOT just a screw like any other screw. Screws have signatures.
After refusing a few samples, they sent a sample of the screw I was already using, and that I had previously bought from them.
YES! I said. I'll take 25,000.
Delivery was supposed to take two weeks.
It took more than a month.
I ran out of my supply yesterday.
I got them today.
I opened the box today.
Crisis mode set in.
They were not the screws I approved, but were exactly a screw that I had earnestly refused. Among the worst of the samples.
They don't want to take them back, because "They meet the ANSI specs" for a 5-40 thread Fillister head screw.
Escuse me? Don't want to fix your error?
Regardless, they're not the screws I approved.
I CANNOT use these screws because of the way they affect my product adversly, and because of appearance issues. I need a good looking, handsome screw with a well formed head. Not a vaguely Coneheaded shape.
Coneheads. Heh.
Approved screw on the RIGHT, Received/refused screw on the LEFT. Notice the taper of the head of the received screw, and the rather "vague" slot for the screwdriver? It's more like..a DITCH dug out of the head.
These screws are 3/4 inch long threads, by the way.
Reversed...different angle. This shows the lack of well-formed, clearly defined top of the head.
Approved screw on the right. How nicely it fills the hole it gets countersunk into. Not so, on the left..
