Here's a pic of my Greenie's original miter gage set screw (top) which had a gray nylon patch and the current ShopSmith replacement part which is a red Nyloc patch set screw. Nyloc doesn't even advertise this "cheapy" red patch on it's website yet it's commercially available.

The way the nylon is applied to the fastener is the fastener goes through induction heating (induction heating = heating with electricity) and once heated, powdered nylon is sprayed on. The nylon melts on contact with the fastener and bonds to the surface.

Very possibly the "nail polish" is Vibra-tite. This is a liquid that is brushed on and dries but stays soft. The screw can be removed and replaced a number of times with no ill effects.

It is safe to use around polycarbonate while loctite 222 and 242 will attack the plastic.

Thank you very much, all of you. It now seems that the nail polish is not nail polish at all and never has been.

All of my set screws look much like the new ones in Mike's photo.

The new process for setscrews may not be new at all but the ones I just received are done with a different color substance and it does appear to be applied as a secondary process.

The red one is one that I received long ago with a hand full of others.
