Steve,
You might check with Keystone Electronics, they specialize in a lot of oddball electronics hardware.

Steve,
You could probably modify these http://www.mcmaster.com/#90910a714/=omte40 by making a block with 4-40 D&T holes on a matrix (20X20?) and fly cut it in one pass. With 2 blocks and an electric screw gun you could probably do a few hundred per hour.
If you need "lots", I know a guy with a CNC screw machine that could make custom screws reasonably.

Hi Richard!
Thanks! But do you have a link to the vendor where that has the ones that have a head height of only .030" ? All the ones I'm finding have a head height of at .059" which is too tall...

You can use a 5/16" 4-40 cap head screw. Same length but the head is only .030" thick. I have attached a picture. It won't show up on the posting, Steve, but you should get it directly.

Morning all,
Looking to find a 5/16" long 4-40 thread wafer head machine screw. It's to fasten down a TO-247 Power Transistor...don't have any clearance for the screw head. That's why I'm looking for a thin head. I only have about .053" clearance for the head of the screw.
Any help would be appreciated...
Steve
