The four bolts are NOT holding the 25k RV. The clamping force between the two pieces the bolts hold is what is holding your RV. The bolts only hold those two pieces in contact with each other, and each bolt is capable of resisting 140,000 pounds per square inch of shearing force.
In any case, nothing is pulling on those bolts, because the load is being handled by the contact between the two flat surfaces the bolts mate together.
Your bolt argument sounds good to the average Joe, but it doesn't hold water to anyone who understands physics or mechanical engineering.
I've got nothing against B&W hitches. I've used them. I find the Curt hitch to be easier. I'm not sure why you hate them so passionately.
Like usual people put words in my mouth!
I fully understand it's the clamping force! Still the FACT is there are only 4 bolts and B&W uses 8 that are for a FACT grade 8.
Have I said anything about "HATING" CURT?
I have pointed out that the FACT is CURT has ALL their 5er hitches in CHINA. Is that "hate" ?
I gave my opinion having hitched with both the B&W and Curt that the Curt is not as easy to hitch as the B&W and the Curt needs to be just right to hitch/latch. Is that "hate" ?
If you were to have left the last sentence you failed to post with the rest of my statement it would have been pretty darn clear that I DO understand the bolts are "clamping" the two pcs of metal together! I gave the example below of two similar conditions with a massive difference of bolts to obtain even a smaller rating than the 4 bolts Curt uses.
"My 21K kingpin hitch has twelve 5/8" grade 8 bolts holding it to the frame and I don't see much difference in the two conditions. "
