Thought this might be useful if you need to fit a few rivnuts but don't have a proper rivnut tool to hand.
You need a long bolt of the correct thread for the rivnut along with a nut and two washers of the correct size plus an oversize nut that is used to stop the rivnut turning. Use the approriate spanners to hold the bolt head and the oversize nut (A and C) still whilst tightening B with another spanner. If you don't have three hands it may be a bit fiddly - i used my bench vice to hold the bolt head in place leaving both hands free for the nuts. This is not possible if you can't take the thing you're fixing the rivnut into to the bench. If you are fitting into a blind hole you'd need to guess how many turns to tighten the nut - I think three complete turns is about right.

Funny I was just about to do something like this myself since it is quite logical if you only have a few to do. Like the tip with the extra, large, nut in the system. Saves me buying a tool specially.

Wow - for inserting smaller rivnuts that is really, really clever
Wouldn't like to use it for stainless M8s though - I can barely do them with a pro tool  Tell someone you love them today because life is short.

Yep - but I put a washer behind it to give the insert something solid to grip on
Used it for the dog guard bracket - used a bit of butyl on the washer to keep it in place on the back of the rivnut when I "squeezed": Click image to enlarge Admin note: this post has had its images recovered from a money grabbing photo hosting site and reinstated Tell someone you love them today because life is short.

Been fitting Rivnuts without the proper setting tool for years (on & off) but having recently just done some more and then seen this thread I thought I would just put in my own twopenethworth.
I found that using a washer / pair of washers / spacer etc against the rivnut was fiddly, not always 100% reliable (sometimes the rivnut still wanted to turn) and also brought the locknut away from the panel which did nothing to help stability (as stated earlier, three hands would help there!) but soon found a foolproof method that works every time and is much easier to use. Just drill a hole the same diameter as the bolt in the end of a flat metal bar and screw the rivnut up against that with the bolt & locknut on the other side. When you tighten the locknut to crush the rivnut, the flange of the rivnut is pressing against the metal strip (which usually holds itself or can be kept in position by finger pressure alone) and will therefore not turn. The advantage of this is that not only is the locknut much closer to the panel & rivnut (making it more stable) but in many situations (and depending on the job in hand and the length of the metal strip you are using) there is often something for the strip to catch on to prevent it rotating which means it really is an easy 2-handed job to hold one spanner and turn the other. The dimensions of the metal bar really are unimportant but it only needs to be about 2-3mm thick, twice as wide as the rivnut and about 100mm in length. A single bar with a different sized hole at each end means one tool for setting two different sizes. This week I have been setting M6, M8 & M10 steel rivnuts and it worked a breeze. ONE LIFE, GET IT! |
