    No. As a matter of fact that is not what I should be thinking about. I did it so I don't ever have to think about it again.

    The whole point of this thread was me asking if there was anybody much...

    I'll 2nd the BK FCR! I bought two of them when I brought the S300/FLEX in (and put one in the R650). Things RIP!
    And, significantly faster roughing than an end-mill (even in a Speedio) if the part...

    Guys, lets not focus on the bolt. Was it not obvious in my very first post that the bolt was not necessarily my concern?

    The stupid U-nuts are the point of focus here.

    While I agree with the general consensus (bad carbide). Do you have any support under the center of that part?
    By the time you get all those slots in there, it ain't very rigid anymore. Harmonics...

    It isn't the bolts I am worried about. It is the U-nuts. These: Amazon.com: The Hillman Group 58456 3/8-16-Inch Regular Extruded U-Nut, 15-Pack: Home Improvement
    And the size of the holes this...

    It isn't the winch that is the problem. And I am not tossing names around.

    People tie off vehicles to winch all the time.
    Some things just need to be built/assembled for the worst case scenario. I think this is one of them.

    In the big picture, opinions don't really...

    That is exactly what I was thinking! And why I was pretty much dumbfounded when I saw them intended to mount a winch bumper.

    I know EXACTLY why they are using them: the design of their bumper...

    Well, I appreciate the input. I'm getting a lot of flack from people saying I am being overly critical, or "out of my league" (true).
    I'm just trying to understand how, what looks to me like a...

    Yea, I can not find a single spec on these things anywhere. Which leads me to believe they are not intended for critical applications.

    I did. They are lower, much much lower than the numbers I (and Cole) are coming up with for a grade-5 bolt.
    I don't know if that is because they are forged? Designed for side-loads? Cut threads...
  16. Well, me not being an engineer, if I were to...

    Well, me not being an engineer, if I were to design, build and sell a WINCH bumper that mounts to the stock bumper mounts?
    I damn sure would not use significantly smaller/weaker hardware to mount it...
  17. No, I am not up to the task. That is why I am...

    No, I am not up to the task. That is why I am asking. I did not design it. I bought it. The 3/8-16 bolts and U-nuts were supplied (china mart bolts).
    The base material is 10ga. Although, the...

    Interesting. So, take the china-mart bolt factor in to account, and I am probably looking at about 6,000lbs?
    But, what about the U-nut? I can't find shit for specs on those things.

    Also, what do...

    According to that, the shear strength would be 4880. And I know bolts are stronger in shear than tension. So, I am not following your math.

    So, your telling me one 3/8 grade-5 bolt will pick up 7700lbs? I don't buy that.

    Okay, my google-fu skills have run dry.
    I am looking for load specs for 3/8-16 U-nuts. Something like this: Amazon.com: The Hillman Group 58456 3/8-16-Inch Regular Extruded U-Nut, 15-Pack: Home...

    Wait, so you have this Axile VMC next to an Okuma M560, and it out-performs it? (no small feat) Why not get another Axile?!

    You are a little late to the party. But thanks for the reply.
    The larger end-mill (as mentioned a ways back) was significantly worse.
    One of the first things I tried. And it was then that I...

    I don't have a drill recommendation (my go to for stuff like this is Walter. But that is because they have never let me down, so that is all I know).
    But, I will say: only way I have ever...
