Problems with removing stuck/rusted nuts

[Guest Sam Davies]

Hi there guys

 

Just wondering what sort of problems you guys have with seized nuts. Are there specific parts that give you the most grief? How often do you have to tackle a problem like this in your daily work? Have you had any bad experiences using a blowtorch to heat them? Has anybody found a better alternative to the blowtorch for removing them?

 

We are thinking about launching a product that will aid in removal of stuck nuts, either rusted or seized with threadlock compound. But it is very important that we get extensive feedback from the guys who will actually be using this product as to what their problems and needs are, so we can design it most effectively.

 

I'd be extremely grateful for any feedback you could give, the more specifically you can describe your problems (and solutions) the better. All information is useful to us, even something you might think to be obvious or not so important. I'd love to get some feedback here and use you guys as a testing board for ideas. We currently have an alpha prototype in the works, when it is ready we will be looking for ten or so workshops willing to test out a completely free (cost and obligation) demo version and give us feedback.

 

I look forward to your responses.

 

Best Regards

Sam

I call my torch, my "gas axe" Whenever I get a car from up north the salt damage is incredible. Most everything you touch on the underside needs to be cut off. Glad I don't see to many of them. Turns into a lot of work.

Being a tech in the rust belt, my torch set is my best friend. We do use rust penetrant, with limited success. Some of the bolts and studs we see are so rusted and corroded, there's nothing left of them. No amount of spray chemical will loosen this up. Seized bolts are one thing, rusted away is another. For some applications, nothing beats the heat wrench.

Living and working in Michigan I see alot of rusted and seized bolts. I can't imagine how it must be in other parts of the country. I have a torch but I find my favorite is my electro-magnetic induction heater, the MiniDuctor. It's kind of pricey but works wonders. The only complaint I have is the life span of the elements due to the insulating sheath burning through on hot fasteners. It's a great tool, but you may have a better idea. The biggest advantage is no flame to damage nearby parts and it's safe, within reason, to use near the fuel tank for those stuck strap bolts. Or I recently had to heat an exhaust manifold to get broken studs out and the brake line, shift cable and other vulnerable parts were nearby. I had to use the torch so I had to shield the parts with a wet shop towel and hope for the best.
