Me removing block studs using heat, hammer and then an extractor from a set supplied by Toolzone, that worked fine.

Nice if you can afford it.
Small second hand Stilson wrench from Chesterfield market (£2.00) with an extension pipe and some heat if necessary. Hasn't failed yet.

These are the ones I like...
https://www.ebay.co.uk/itm/I-Set-of-Syke...SwE~1cHMzk Keep an eye out for them. I recall I paid no more than a tenner for my set, though to be fair, I suppose that is more than 2 quid on Chesterfield market... :o)

Good information thanks Jeff Taylor. The Wurth product looks especially good. What, I wonder "dissolves" the rust? An acid?
I was particularly interested to see that the cooling effect is said to open pathways for the lubricating part of the mixture. This would suggest that, without the contraction due to cooling, penetrating oil wouldn't penetrate well rusted threads.

Glad to hear it works OK for you, but the biggest problem with using Stilsons or Mole grips is that they pretty much always mark the studs up. A marked & damaged stud is a WEAK stud. Best to avoid this sort of damage if at all possible. My preference is the Sykes type mentioned numerous times above. A metric set works perfectly well on imperial studs, all be it sometimes 1/4" studs are a little difficult to get down the extractor. Having said that when extracting 1/4" studs I usually use the 2 nut method as a 1/2" drive extractor seems like overkill to me.

I wouldn't have thought there was much point in re-using a stud that had to be removed using any sort of extractor system or heat for that matter. I would prefer to replace with new. The Stilson method is not "sympathetic" but it is effective - small flats made with an angle grinder can assist with leverage and grip.
I bought a set from Halfords a few years ago, metric but they fit the imperial studs I've used them on, if needing a wiggle to get them off occasionally. It uses a cam type roller system rather than the knurled single cam type which really does chew up studs. I'd say the roller system is quite kind to the studs, smooth as the rollers are they don't seem to slip but will mark a stud if you need to apply a lot of force.

Totally agree with Reckers, if you need excessive force to get the stud out it’s scrap. I also use stilsons when necessary, or weld a nut to the stud.I have no interest in saving the stud! |
