[This review was collected as part of a promotion.] I picked up a 5pc bolt biter set (86191). The kit is well packaged and in a very nice case. Case is something like use only in an emergency type of case. Overall wet solid kit - something you will need when you desperately need it at most. Very universal that covers a good range of common sizes. This kit came in clutch when I had to swap out a bad chain on the kiddo’s bike. A lot of the hardware was all seized up from poor bike store build. Surprisingly most of the fasteners were rounded. To save the day came the bolt biter kit!! Literally fit every bolt I needed it on snug and got that sucker out!! I’ll invest into the bigger kit soon, and this can be the kit I leave at home or take on the go with me.

[This review was collected as part of a promotion.] The Gear Wrench Bolt Biters are useful for rounded off fastners. But often I use these Bolt Biters on acid corroded battery terminals. These Bolt Biters have great grip for some of the most froze on fastners to be removed. They work well. The only disappointment I have with this product is that each Bolt Biters have a thick edge that tends to not allow fitment that are close together, each bolt needs adequate spacing between each bolt and fastner or this tool wont fit properly. Another disappointment is the tools color accent paint, it seemed dry to brittle, upon opening the paint was already flaking off, so presentation isn't to impressive.

[This review was collected as part of a promotion.] Another win for gearwrench bolt bitter. You dp know you need them until you have them. Not the run at the mill parts house extractors. Built with quilty and have good weight to them. Cant eait to get my hands on the rest of them!
