Review: Working in a shop, you run across vehicles that have seen many hands and tools on them. It is a given that you will run across some rounded off bolts and nuts. It’s also a given that the rounded off nut amd bolt is in such a spot that you can’t use a socket style extractor. This set is pretty good, has inserts for metric and standard. And is designed to used with a ratchet or a wrench. Place it over your bothersome fastener, give it a few love taps with a dead blow hammer and apply torque. I’ve had to use 3 different sizes and had success with all three. I did not notice that when a had a bolt that was stuck pretty good and had to put some serious torque on them, I could feel a little bit of slipping, so I gave a couple more taps and used some spray lube and they came out pretty easily. It’s one of those tools that you hope to never use, but when you need it, it’s worth it’s weight in gold. So far they are performing very well.

Review: I bought these because I had bought a car that the oil drain plug was stripped. It was extremely tight! This removed it with ease, using a long ratchet!

Review: The Bolt Biter inserts are disappointing compared to the Bolt Biter sockets (¼”, ⅜”, & ½”) and other extractor sockets in my shop. I have the full sets of the socket style Bolt Biter extractors and a small set of RocketSockets, but bought the inserts for bolts in a small space (the first test being a bolt for a wheel bearing on a GM w-body car that’s confined by the CV axle into the knuckle/spindle) and to keep in my travel bag for farm/ag work when away from the shop. After tapping the bolt biter on and starting to turn it with a wrench, the insert’s ‘teeth’ steel gave way and just rounded the insert out. This flattened the teeth inside the insert but didn’t make any progress loosening the fastener or even rounding steel off the bolt head suggesting the bolt is much tougher steel than these. Eventually I removed the knuckle from the car to replace it with a salvage yard part, but I wanted to at least give the inserts a fair shake by using them in more ideal circumstances, not awkward angles. I tried the next size smaller, ½-, and I had to tap it onto the rounded bolt but not beat it on with a sledge, just a few taps with a ball peen to seat it and make sure it was a snug fit. With the slightly smaller insert, I experienced the same failure point with the insert rounding out and only chewing the bolt up a bit more. Pictures of the rounded bolt (a gift from the car’s previous owner presumably!) and the chewed up inserts are attached.These would likely work well on softer metals like brake bleeders, zerk fittings, or bolts with a deeper head, but the steel they’re made with is softer than standard automotive hardware, so if a bolt is cross-threaded or really rounded and rust-welded, these will not provide assistance. At this point, the stuck bolt needs to be cut for a flat head driver attempt (unlikely to work since that provides less force and leverage overall), or ground off and drill it out since the inserts certainly didn’t help the rounded bolt head situation.Note: On Gearwrench promotional material for these, some of the examples have them improperly being used and sitting on fasteners backwards. Be aware of the taper in these inserts and ensure the wide flange side is what’s on the bolt head that you’re trying to remove.I’m generally a fan of Gearwrench tools and a significant amount of my every day ratchets, wrenches, and sockets are GW tools, so I’ve generally been pleased with the durability and usage of their tools. The Bolt Biters miss the mark, though.
