Yes, it's ok to tighten them. If you can get to the back, of course, then nuts and bolts may be better. Darren

That's what i was thinking for the top two. AFAIK LR fitted them but IMO are not strong enough for purpose. There isn't even a washer on the back.

Not having a washer on the back isn't that big a deal, assuming they're fitted properly. They are designed to fit into panels where access to the rear isn't possible anyway. Darren

Very true, but there is access on these two and I get the impression it was done quickly just to get it on. ⭐️⭐️God Bless the USA 🇬🇧🇺🇸 ⭐️⭐️

Old post revival I know, but as a 'Sticky' I thought this maybe useful. Image below is taken from the LR OEM Lamp Guard fitting instructions. Shows a very simplistic method of fitting rivnuts. Haven't tried it myself (yet!) but it bears some resemblance to the method described by Litch regarding the flat metal strip.

Hello All
This is worth a look if your working out how to approach this... Both with and without a Tool... fitting the Defender Front Light Guards also gets a mention. The usual requirement of needing 3 hands when using a home made Tool is also refereed to...

Hi,
For small size rivnuts (al or st) i use ordinary pop up rivet tool by some little changes. What you need is a threaded rod with a suitable length and same size with the nut. A thick washer and a normal nut (may be two). If you remove the capsule holding the jaws and the spring, you can easily insert the rod. All you need is stretching movement of the rivet tool that it is still capable of.

having successfully ruined my poor fathers hands (blind leading the blind) and both of us getting blood everywhere, i say this...if you are going to use the crap method they give you in the destruction manual, then dont...its easier and kinder on your hands to buy the tool with the many mandrels needed... you wont regret it and the car is held together by rivets so there is always another mod or fix that requires them
 defo worth the investment |

Hi
As others, I apologise for opening this up again but I have spent a frustrating afternoon shearing bolts and rounding nuts using the DIY method. See pic. It is only a 6mm but it hardly flexes until the bolt shears or nut rounds or my muscles give in. My question is that is it possible some (cheap) rivnuts are rock hard and will not work with the DIY method. I only have two to do so dont want to waste loads o money on a tool. Perhaps someone can recommend a 'soft' brand of riv nut
Thanks Grouse 2 |

Feel your pain. I have found exactly the same in the past and gave up after about only 50% success. Same issues as you have had. It only to get you out of trouble but anything more than that, buying the tool is the way to go👍

It’s almost impossibly to crush the steel rivnuts with the simple home made tool. However the aluminium rivnuts will work well with the home made tool.

I think your problem lies with the nut and bolt, not the rivnut.
Most coach bolts are 4.8 grade at best, which is roughly comparable to mature cheddar. I've done loads the DIY way using decent 8.8 bolts and grade 8 nuts. Equally a short armed rivnut setter is only £35 on Amazon and works well! |
