Product Overview

Bolt Biter is the revolutionary new extraction socket system from GearWrench. We talked with auto mechanics and industrial techs to learn what they hated about existing extraction sockets. Bolt Biter redefines extraction and solves all of their frustrations. Bolt Biter grips rusted or rounded fasteners instead of cutting into them, which means that these sockets last 10 times longer than the competition when used with an impact gun. That’s why they carry a lifetime warranty, we built Bolt Biter to match the strength of our traditional impact sockets. Bolt Biter has a bi-directional design that can tighten or re-use a damaged fastener just as well as it can remove it, making it perfect for specialized components. But durability and re-use are just the start. This improved design also seats easily onto the fastener, so you don’t have to swing a mallet under the hood. Fasteners don’t get jammed in the socket – unlike old-school extraction sockets. Bolt Biter even fits a wider range of fasteners, with “minus-size” sockets designed to fit onto fasteners worn down past their original size. Forge Ahead with Bolt Biter, the innovative leader in extraction.
  • Bi-directional design for removing or tightening damaged fasteners
  • Tapered entry enables socket to easily seat on a damaged fastener
  • Dual sized sockets designed to work with both SAE and metric fasteners
  • Square drive with hex base for use with impact gun, ratchet, wrench or pliers
  • Chrome molybdenum alloy steel (Cr-Mo) for exceptional strength and long lasting durability
  • High-visibility laser-etched markings provide quick size identification
  • Black oxide coating provides superior corrosion resistance
  • Up to 10X longer impact life versus competition
  • Up to 5x greater torque output vs. competition
  • Minus-size sockets fit a wider range of damaged fasteners
  • Blow mold case included for durable storage and organization

will this tool work on very bad strip round bolt, plyer will not grip, socket just keep turning.....

Hi Jessie, I have used it on rounded off exhaust bolts and water pump bolts and it works quite well. As long as the tool has a good gripping surface it should remove your bolt. B62

will these work with left-handed thread bolts

I have not tried to use them on a LH thread fastener but looking at the design, I believe they will. They work great for every other use I have had for them and find they work much better than other similar tools designed for the same work. I highly recommend them.

Looks like 1/4” (6mm) to 3/4” (19mm) in the photo. I don’t have it but was wondering the same thing so I zoomed in on the first photo. Don’t hold it against me if I’m wrong, just going off what I see.

got to a point in doing many projects that I needed a bolt Extractor kit. I’ve started working on a 1967 Olds 425 that I plan on swapping into my Olds. My Olds has long tube headers so there’s no need for factory exhaust manifolds. I got 8 of the 10 bolts out no problem. The last two, would not budge. These bolts probably haven’t been removed since put in at the factory back in 1967 (52 years ago) I hit the bolts with WD-40 but I don’t think any got in because of the downward angle. It took less than 5 minutes to get both stubborn bolts out, combined. They were bolt 9/16 head bolts, need the 14mm for one and the 13mm/ 1/2 inch for the other, yeah pretty rounded. The bolt holes on the head are clean, bolts didn’t break or snap. They are out and now onto the next step in my project! Get these. You will not be disappointed

Sometimes you cant fit a pair of locking pliers or some other more extreme methods I have used over the years to get rusted out nuts and bolts off in the space available. Since I work at the beach everything rusts and replacement of hardware is a regular process. Occasionally something gets skipped in the rotation and it no longer looks like a nut or bolt when we find it. I went searching to give these a test and found a nut in a cramped place with moderate corrosion. I picked the size extractor that matched the nut size before rusting and put it on a ratchet. It bit right in and came off without a fuss. I was curious if I could then put it back on and had no issues, just like with a standard socket on a new nut. These will get a spot in my maintenance bag in my truck for the inevitable rusty fastener.

These 1/4 IN. AND 3/8 IN. BOLT BITER IMPAC EXTRACTION SOCKET SET is an 8-piece set. Depending on which socket you use, it takes either a 3/8 or 1/4 in. Inpatient or regular socket wrench. It works great on either regular headed bolts or /bolts that are stripped out. The set comes on a mountable bracket, so you an put it where you want it. Great product.

I have always been pleased with any Gearwrench tool I have used and this is no exception. This extraction socket set would be a valuable addition to any mechanic or handyman's tool box. Not only do they work terrific as advertised at removing damaged bolts but they serve a much more valuable purpose when in the hands of someone who is performing restoration work to anything that is enhanced by keeping period hardware as opposed to replacing it with something contemporary. I am currently working on restoring a 1800's treadle powered lathe which has square headed bolts. It can be a challenge to remove/install square headed bolts because they are more prone to accidental damage when using a typical socket or wrench especially under high torque situations. These Gearwrench Bolt Biter Sockets work GREAT and have minimized that risk! They are impact tool tough, designed to be used with both ratchet or wrench and I just cannot offer enough praise for this tool set. I highly recommend them!

1/4 in. and 3/8 in. Drive Bolt Biter Impact Extraction Socket Set. My Mother and Father had this old glider swing, just outside of the back door. The slats have long since rotten out. All of the bolts had rusted out. These Bolt Biter sockets allowed me to remove the bolts!! I was albe to to refinish the glider, new slats, bolts, nuts and painting the frame in a total of 5 hours. These sockets also work great to drive the new bolts. These sockets stay in my general tool box, for every day. I use these almost every day, makes my job much easier!

I have several other items from gearwrench and they're pretty solid and won' fail the typical homeowner or DIY mechanic. These items are no exception. I've used other sets before that only last a couple of times and wear out. The finish on the bits themselves is pretty good and should hold up in a garage climate unless you have extreme temperatures. Its a great set at a great price.

This socket set from GearWrench are so amazing. They do an excellent job of grabbing a rounded over bolt allow you to loosen it or if needed tighten it back up. The set comes with 8 sockets all that have the bolt biter to allow you to tighten or loosen ranging in a wide range of size and each socket is designed to work with both SAE and metric fasteners. Additionally, the sockets are impact rated so you can use them with your impact wrench and not worry that you will break them. Just over all a great set that you may not always come into a situation where you will need them but when you do you will be super grateful that you went with this set from GearWrench. I would definitely recommend picking up a set and know that you have piece of mind because of the lifetime warranty offered by GearWrench.

Living right on the ocean the salt air and water takes it's toll on fasteners. They freeze in place or rust and corrode and need to be replaced. I have other gear wrench tools and I like their quality. The bolt biter can be used on metric, SAE, or worn damaged fasteners. The sockets can be used with a hand wrench or power tools or pliers. The socket grips in both directions so in a pinch the damaged fastener can be reinstalled. The black oxide coating is corrosion resistant and the chrome molybdenum alloy steel has exceptional strength and durability. Best of all the fastener can not get jammed in the socket. The set has 8 sized sockets and has a lifetime warranty.
