Reese River Nut #58507 undersize - too loose for 75 ft/lbs
Hello,
My DW and I bought a used 2015 Rockwood Windjammer 3025W back in January after our local RV show. I'll be reusing using my Reese Dual Cam #26002 on the Windjammer.
We used this hitch on our previous trailer for about 15 years and I will be transferring it to the Windjammer.
However, 15 years ago you didn't use these rivets to secure the Frame Plate to the trailer frame. You just drilled the four holes and used 1/2-13 thread forming bolts to hold it on. Needless to say, they loosened up on me over the years.
But now they require rivets #58507. Instructions tell you to drill out 11/16" hole for the rivets. It says it must be a snug fit. That's not the way it's working with me.
11/16" is 0.6875". The problem I have is that the rivets have an outside diameter of 0.6795" to 0.681".
These rivets are 0.006" to 0.007" undersize for the 11/16" hole. I tested them and drilled 11/16" hole and popped in a rivet and it was undersize by several thousands, it spun easily, no friction, no snug fit. I measured in the knurled area that's gonna do all the gripping.
I complained to the vendor and they sent me a new pack. Same thing, undersize.
The rivet nuts need to deform as they are tightened. The instructions tell you what to do if they start to spin while you're tightening them but that is all depending on a snug fit. And they require a torque of 75 ft/lbs.
Has anyone else dealt with this? I can use a smaller drill size, but is being installed at the dealer. And people that didn't check it out like I did are going to have undersize rivet.
I worked in manufacturing for more than 30 years and I not a measure. I use both a digital vernier and a 1 inch micrometer. These rivets are undersize for 11/16" hole.
Should I contact the manufacturer? Because putting these rivets in if they're not tight enough is a dangerous situation.
Thanks.
