OK, so couple of my zerk fittings on the propshaft/u joints broke clean off.

I've tried several different plain jane screw extractors with carbide tips and reverse cuts in them. These, however, just seems to slip around.

Any of you have experience w/ screw extractors that's bulletproof?

FYI, I've looked through catalogs from Grainger, MSC, etc. and there seems to be a lot of different kinds of extractors out there. Some of these kits cost around $30 or more, so just wanted to get some feedback before I order some.

Thanks

Insure that the extractor is not bottoming out into the shaft and causing it not to be able to grab the broken zerk. You may have to drop the drive shaft to get clearance between the extractor and the male part of the shaft so the extractor can seat properly in the zerk. I have found that it is sometimes quiker to drop the shaft and get it on the work bench than trying to fight it for HOURS under the rig. Broken fittings can be a real Pain in the butt :cry:

HAve you tried this style. I use a #31 drill with the 1/8th extractor.
if you dont have a #31 a #30 or 1/8th will also work.

this style is slightly smaller.

these tapered straight shank extractors are much more robust but might be too big and not the right tool for this job.

i have had very good luck with left-hand drill bits and usually go to them first now days.

is it broken off flush or is there any material protruding? a set like this might work.

all of these styles have their place, i use them all for different jobs and you just have to practice and get a feel for which type is best for your particular problem.

I didn't realize Snap On had so many choices of screw extractors! I wished they priced their goods a bit lower, so I don't feel guilty buying their stuff.

Thanks for all the input, btw.

I've bought couple different screw extractors, so keep you guys posted on which one worked the best. Worst case, I'm just gonna replace my u joints.

I consider extractors to be consumables, so the price is much more attractive when you can get them replaced under warrenty as they wear out or God forbid break in a fastener.
