Albin, The "myths" as you like to call them, maybe myths in the automotive industry where your dealing with a vehicle that weighs 6,000 - 8,000 lb's., but in heavy industry where your dealing with loads of several hundred tons of force these "myths" become reality very quickly. You are correct...

Jake, With the gooseneck the bolts almost always only in shear. They are not holding any weight, since the hitch frame is setting directly on the truck frame. Where as the receiver hitch is usually mounted under the frame hanging off of the bolts, so the tongue weight is then transfered to bolts...

Jake, A grade 5 bolt is an acceptable bolt for a hitch if it is large enough in diameter. The advantage of a grade 5 over a grade 8 is it's ability to stretch before it breaks. It is almost like comparing apples to oranges when your talking bolt grades and diameters. You have to ask yourself...

I agree with you on several points, but I respectfully dissagree with you on most. I stand by my initial write up. Grade 8 bolts ARE prone to failure due to shock loading at a higher rate then A-325's, where as A-325's are specifically designed for shock loading. I have worked for companies...

Yes, cadmium, zinc electroplate, yellow zinc chromate, hot dipped galvaized, all plating works as a lubricate. I learned this lesson the hard way assembling a pedestal crane with 1" grade 9 bolts, and was busting them in two at only 75% torque load. I ALWAYS lubricate hardware EXCEPT when...

Glad to be of help. With stainless steel you still have to be careful of grade. Most hardware stores only carry a 304 grade bolt, which would be the equivalent of a grade 5. The next most common grade up would be a 316 which is almost a grade 8. Another good thing to remember is that most...

I just installed a Curt on the back of my bobbed deuce. I have a "Ranch Hand" front bumper on my Ford Super Duty that has the receiver. I haven't used it yet, but I really like having it there. I'm gathering up material right now to start fabricating my bumpers for the deuce, and I really think...

Hey guys, I think we should do a little research into using the proper hardware for bolting up these hitches. Grade "8" bolt is actualy TOO HARD, for this application. These bolts are good for an installation under constant stress load, but not for something that takes a "shock" load. Grade 8's...
