riv nut stud in automotive ?

[C.L S2000]

Hello GJ,

I am new to GJ but have already seen a lot of interesting and educational posts here on GJ. I was curious if any have seen this type of fastener and if its used in automotive or industrial fields ?

Harbor Freight uses those on their Yukon tool boxes to mount the casters to. See video:

Thanks Wamsutta for the feedback. I believe I seen the regular riv nuts which is in the video, I was curious if you maybe seen the riv nut stud used on anything ?

commercially it is used a lot in communications cabinets and gear, racks and raceways, covers and so on.

Used to be used, or similar ones, in automotive work/builds - but with composite panels and recent adhesives, hard fasteners have been shoved aside for tabs and buttons and so on.

BMW has nutserts for the license plate mounts sometimes

i'm sure your rivnut stud is just a rivnut with a little all thread screwed into it.

I don’t know about commercially, but I use them. I’ve used them to install my amp research power steps on my truck, and also to mount a bracket for an air compressor/tank for a buddy in his truck.

I don’t reach for them often, but when I do, there is good reason. I ,over those things (as long as you drill the hole the right size ).

The biggest issue with riv nuts are they have a tendency to spin if they are over torqued or they were not installed correctly from the start. I know I had several do that and in a blind application where you can not get to the other side it is a pain in the a$$.


I personally prefer clip on nut plates as they do not do this, but in a location that can be rusted they are a pain also or if a tab breaks you might as well get out a good drill as either case you will be drilling them out.

Thank you everyone for the replies. I always seen these but never knew what application for automotive (or commercial) they were used in. I'm in the automotive industry which is why I'm curious if these could make my life easier or not.

Some auto use, but not much. I'd say assembly or maybe aerospace manufacturing

I just retired last May from Boeing after 30 years and I worked on assembling of new aircraft. In actual manufacturing Boeing did not use riv nuts for the reason in areas where riv nut might be used we used clip on nut plates. In areas where a the clip on nut plates would not work we used nut plates that were drilled and fastened to the structure. Riv nuts were not used as they have to be perfectly installed or they could/would spin if they are slightly over torqued.

They might be used by the vendor for a seat, galleys or lavatories as Boeing does not make their own seats, galleys or lavatories but in critical areas that would be safety of flight riv nuts are not used.

Honda uses them for accessory running boards and sidestep bars installed at the dealer or by the DIY guy at home.

There would also have to be a means of preventing it from unscrewing from the rivnut. I am sure they don't use allthread and Loctite. Thay are undoubtedly made from two pieces and you could probably kluge one together, as you said but commercially they are made to stay together.
