Re: Jaguar/Victor screw supplier

I would like to add that I would prefer binding head screws in this application if I was placing an order. All screws are not created equal.

Re: Jaguar/Victor screw supplier

I would recommend removing every single painted screw and throwing them in the garbage. There are markings on the motor controllers themselves, and those screws can and will get accidently swapped around. I know this from experience. If you rely on screw color you WILL eventually kill a motor controller. It's not a question of "if", just a question of "when".

Get people used to looking at the markings on the motor controller. If you have trouble seeing them, paint those, not the screws. You'll be happy you did in the long run.

Doing this on a gray Jaguar leaves metal debris inside the unit. Not good. The effect is the same for a Victor (I believe) except the Victor is conformally coated so that the debris is typically left largely trapped in the coating itself (the coating wicks up the terminals).

What I encourage my team to do with Black Jaguars is to only remove and replace one screw at a time (if they need to remove a screw). If they're disciplined in this practice, the screw colors can be of use. Of course I also encourage them to follow "Trust, but verify".

Re: Jaguar/Victor screw supplier

I recommend that you also check into the finish of the screws that you will be getting. Certain finishes can create conductive particles, which can contribute to arcing across the terminals of your Victor or Jaguar.

Al or Bruce -- do button head socket cap screw perform similarly to binding head screws? I agree with Bruce that it is easier to control the screw torque using a Torx head driver. The CAD view available on McMaster appear to show similar holding surfaces (under the head) for both types.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
