As far as I know the metal ones aren't available. Place a wtb ad or hit the junkyard. Any particular reason you want a metal one?
 
They haven't been available for many many years. I mainly saw them in 1990-1994 throttle bodies for DSM, or for the 3000GT platform. The plastic ones work just fine with a new o-ring and dust cap.

Here's some throttle body part numbers for reference -
BISS Screw - MD614948
BISS Screw Cap (1G) - MD614150
BISS Screw Cap (2G) - MD614532
BISS Screw O-ring - MD608806
1990 Throttle Body Inner Gasket - MD125822
1990 Throttle Body Outer Gasket - MD340327
1991-1992 Throttle Body Inner Gasket - MD146399
1991-1992 Throttle Body Outer Gasket - MD340327
1995-1999 Throttle Body Inner Gasket - MD184046
1995-1999 Throttle Body Outer Gasket - MD302262
1990 Idle Speed Controller O-ring - MD614299
1G Idle Speed Controller O-ring - MD614417
2G Idle Speed Controller O-ring - MD614417
1990 FIAV Gasket - MD614300
1G FIAV Gasket - MD614406
2G FIAV Gasket - MD614406
 
Thank you everyone for all the information. And the reason I want a metal one is because the plastic ones strip out to easily. Which I've experienced firsthand too many times. I've heard of them being in some of the hyundais and that those would work. I'll just have to find someone selling one I guess.
 
I hope you can find what you're looking for, but if it's any solace, my 1999 has had a plastic biss screw that's never been touched and never backed out on its own. Recently I spent 5 bucks replacing the oring on it and put it back in, car runs like a brand new 1g and hopefully good for 16 more years!
 
Yeah I'm not sure I follow either. I've adjusted so many over the years including my own personal. None of the plastic stripped. Is your throttle body messed up?
 
I usually see them disintegrate in customer throttle bodies, when I install new ones I use a high-temp synthetic grease on the threads, o-ring and BISS cap, along with the shaft seals, TPS sealing washer, and ISC o-ring.
