The better way to do this, is use the tap Before it starts spinning. And moderately hard to install bolt - remove, tap, and then put the bolt back in.
This is another one of those vanlife trends that got spread through influencers that nobody bothered to understand before applying.Plus Nuts provide the ultimate pull out strength in thin metals and plastic. They feature the widest grip range of any blind threaded inserts. The solution is to add a spacer (washer) when using Plus nuts in thin sheet metal. Search Plus nut.
Yes. The Transit sheet metal is not "thin", it's probably right in the middle of available sheet metal gauges (probably closer to bar-stock than the thinnest sheet metals, even).so pull-out resistance, Plus-nut 2.5 more vs RIVNUT.
in shear the screw or bolt will be the limiting factor
what other loads are you referring to?
From the document you posted:Even the inventor (who invented both plusnuts and rivnuts) recommend plusnuts only for plastics
I agree with your general sentiment here, and there are certainly many examples that can be pointed out.This is another one of those vanlife trends that got spread through influencers that nobody bothered to understand before applying.
The document you posted does show some comparison data for pure axial loading (fancy word for pull out force) I understand your theoretical explanation of the forces/strength for but have never seen any comparative test data from Bollhoff. Is there any test info/claims from them or other manufacturers that you know of? I would honestly be very interested in such info. Certainly the strength perpendicular to pull out is very important in a van.Rivnuts are stronger than plus nuts in almost every loading condition except pure axial load ...
The rivnut is stronger and resists deformation better than the plusnut in all directions except pure pull-out force
I have also installed a hundred or so plusnuts (M5, M6, M8) without any spinners. Mostly transit sheet metal to hold heavy things against walls.I’ve installed at least 300 plus nuts in my van and not one of them spin. It’s not that hard. Use the mcmaster tool and a torque wrench. Clean up any threads that need it with a tap. Use a washer below the head of the plusnut when installing. If you do those things, you have pretty much 0 chance of a spinner, which is the only real downside compared to rivnuts. Plus nuts are a lot more lenient on hole size than rivnuts, which is useful when using existing holes in the van.
rivnuts are fine, but using mostly M6/ 1/4 hardware, you want all the pull out you can get in the (very thin) .7mm transit sheet metal
