[This review was collected as part of a promotion.] Gone are the days of wasted time trying to extract a stripped bolt head with pliers! These Bolt Biter Nut Extractor bits are magic. I could not believe how easy it was to remove a rusted/stripped sheetmetal screw from an old vehicle. I wish I had these bits many years ago. The time and frustration that I would have saved!! The quality and packaging is top notch. The handy storage case keeps the bits organized for quick reference. These are my "go to" bits now and reside in the top drawer of my tool box.

[This review was collected as part of a promotion.] These are great, they work without slipping. I have a small engine repair shop, so I use tools all day. So when we run across rounded nuts I pull these out pick the right size they grip onto the rounded sides of rounded nuts and spin them off.

[This review was collected as part of a promotion.] Just got the chance to use the bolt biters and gripped a stripped out bolt very easy. Comes with plenty of sizing for smaller bolts. It has a nice case as well. These will definitely come in handy being a mechanic

[This review was collected as part of a promotion.] We had a stripped transfer case bolt we couldn’t extract. We pulled out the Gear Wrench Bolt Biter set and within less than a minute we had the bolt out. We recommend this for both at home mechanics and in a professional setting which is where we were able to use this.
