Bolt Extractor Offset Wrench Set - 7pc Rounded Fastener Remover Kit - 6-Point Box-End Metric Design - Stripped Bolt & Nut Removal Tool - Professional Grade Mechanic Wrenches - Part: 1311

Fantastic!! If you have a real bad bolt/nut, try and add some heat to it with a small torch and then use these. Worked wonders for me. I don't like to spend alot on tools either, but these were worth every penny..

These are definitely great I tried them both ways they work both ways

It is getting difficult to find offset box end wrenches like this around here. I didn't notice in the description of these wrenches but it an intuitive concept that seems so fa to work well. Instead of 6 or 12 point as many have, these have flat wedges that actually do the gripping on the point and part of the side of the nu/bolt being subjected to. This is good to prevent rounding. I haven't tridd on a rounded object yet to see if it will need to be filed/ground off go get a smooth surface but it should be "foriving" and work ok.

I've been keeping an eye Olsa Tools for the past few years, it's been amazing watching them grow! These wrenches have some serious bite to them if you can get then fully seated on a rounded nut. I got to use these for the first time a few days ago and was definitely impressed. Got me out of a really sticky situation on a John Deere skid steer with a Yanmar engine. Had high hours and the exhaust aftertreatment had never been off, so the hardware was NOT playing nice. These wrenches were the only tool in my arsenal before busting out the liquid wrench that was able to break them loose. Then I was able to proceed as normal! Gotta say, these really are impressive. And it beats paying the fortune the tool trucks are asking for similar products.

Had a 19mm nut stuck by rust. Tried loads of oil snd heat. But every time i tried a normal wrench the nut started to deform and not move. Figuerd i migth as well try this kit. Put on this wrench and pulled as hard as i could and nut got lose. So this is a tool set that i am happy to have the next time i am in rust hell and cant fit a impact hammer

I soaked the bolt in WD-40 during the night before trying to remove it, but that didn't help. The bolt is the original one which has secured the locking mechanism of the hood for a 1969 Dodge Dart, btw. The extractor's teeth are just not tall or sharp enough to hold on to or dig into the rounded-off edge of that infamous 52-year-old bolt. I've also tried with sockets made for extracting damaged stuff like this. Nothing doing! Maybe because the guilty party is in a confined space and the socket was too big. The other bolt which has also secured the mechanism for years I managed to twist it away with no difficulties with a standard 1/2 inch wrench, though. I will drill that bolt off, instead. I gave this set four stars because I know these wrenches will work on bolts which are not as messed up as the one I'm referencing right now. Also because the extracting wrenches come in a nice box and case, and also because they appear to be made in Canada. No Made in China nowhere on the box! PS: Maybe because I used the 13mm wrench on a 1/2 inch bolt the extraction was unsuccesful, come to think of it.

These won't extract a bolt with a completely rounded head. However, they do a good job as long as there is some material there. Or even better, use them on bolts you feel are slipping before you have rounded them at all. It will help preserve the head. The heads are nice an compact and I could get them to fit in and around an exhaust manifold where nothing else would go. Tools seem well made are polished to a jewel like finish.

I had a nut that wouldn't come off the bottom of the turbo charger. I had tried for hours trying to get it loose to no avail. The head of the nut was damaged, and it was in a place where I couldn't use my extractor sockets. I didn't want to try and cut the nut off and risk damaging the turbo charger. Found these on amazon and they worked like a charm. Less than 5 min and it was off. I couldn't be happier about this purchase

Very well made tools. Worked as described on rusted nuts .

High quality extractor wrenches. Completely rounded a bolt on an exhaust heat shield. These wrenches gripped and took it out with ease. The tray looks great and matches my snap on trays. My first order was missing 2 wrenches right out of the box. Olsa customer service was great and send a replacement right away. Great tools. Great company. Highly recommend their magnetic socket organizers aswell.

Expensive, but worth it.

Yep these work good stuff

Work's great
