Dzus Fastener Sizing

[Jason Oldfield]

Can somebody help me size / select a Dzus fastener? What I want is what I would call a button-head Dzus fastener with an ALLEN (Hex) drive (this is going in an area with limited clearance, and a standard Dzus tool will have a hard time getting in there). I don't need anything that's self-ejecting, just the Dzus (I think they actually refer to them as buttons) itself.

Moroso APPEARS to make what I want, but I can't match the dimensions to ANY dimensions of the Dzus I currently have. The size I have (and would need to make sure that the shaft diameter and length were the same) is as follows:

Head Diameter: 0.675"
Shaft Diameter: 0.406" (0.400" nominal?)
Overall Length: 0.775"
Shaft Length: 0.660" (from bottom of button head to end of shaft)

I don't care about the material (the ones I have now are steel, which is fine), and I generally don't care about cost because I only need two of them (though I know I'm probably going to need to buy 10). The only things I really care about is that it works in place of the fastener that I have now (I'd prefer them to be silver-ish in color, but really they could be any color).

Thanks in advance...
