Theaded on easily - not easily scratched by tool - color close to black, not to green.
Great quality and fast shipping
Nicely machined and finished.. I was surprised that it even has a staking notch too!
This particular castle nut has great fitment, tight tolerances, and nicely cut threads. The finish is very uniform and presents a proper blackened phosphate treatment. The material hardness holds up well when torquing to specifications and did not mar or deform like some I have used from other suppliers, both higher and lower cost. I use these often and this where I get all of them from!
it has a nice finish and the notches are clean
