Never Let a Rounded Bolt Stop You Again
Meet the GEARWRENCH 5 Piece Bolt Biter Metric Wrench Insert Set – the ultimate solution for one of the most frustrating jobs in the shop: rounded, frozen, or damaged fasteners.

The Bolt Biter system changes the game.
These inserts are an incredible 70% thinner than standard extraction tools, allowing you to slide them into tight spaces where no socket could ever fit. Use them with any 6-point, 12-point, or even ratcheting wrench in your toolbox. The revolutionary bi-directional design not only grips to remove the toughest stuck bolts but also allows you to tighten damaged fasteners, making it perfect for emergency repairs. This set isn't just a tool; it's a timesaver.

Love this set!!!
Size: Medium (2.5"), Style: Fetch Pack 1
I was trying to figure out which of the many different balls this company offers, and I was getting frustrated but then i was SOOOO happy to see they had multiple sets that had multiple of the different balls they offer!! I bought this set and the other set they offer, but this one was my favorite and I think my dogs too! The orange ball works great and bounces just high enough that it doesn’t clear our patio wall, but enough for him to go and jump up to retrieve. But the glow in the dark ball is his favorite! Both me and my pomsky were blown away how we brought the glow in the dark ball outside just as the sun was going down, and when we brought it back inside it was BRIGHT AND GLOWY!!! Even with the sun going down and not much light left!! He loves to play with it in the house after it’s all glowy from the sun. Sometimes we even glow it up under a light inside the house if it’s dark outside, and he will play with it outside in the dark haha he loves it!!! And I think it’s pretty cool too!! All of the balls this company overs are VERY durable! We realized early on that we cannot give our dog regular tennis balls cuz his favorite thing to do is tear the outside fabric off!! So we were trying to figure out what company has the best balls for dogs so they can’t sit there and try to pry them apart, and we found this company!! We have already bought from them about 3 times and all of their balls are durable and bounce how they say they will bounce!! They have the super bouncers and the glow in the dark one and the one with angles that will bounce in different directions and the ones you can throw REALLYY far! Overall, all the balls from this company are very durable, bounce really good, and keep my dog occupied without allowing him to sit there and tear it apart!!! Which i love cuz I do not like when he stops playing with us to sit there and try to take off the fabric, cuz then he could swallow it! So always buy the balls from this company!!! They are the best and most durable!!!! Also plenty soft for your dogs mouth so they can chew on it a bit and it won’t hurt their teeth/gums!

Good sturdy balls
Size: Medium (2.5"), Style: Fetch Pack 2
My dogs love balls! Unfortunately, they tend to chew them up very quickly. My Belgium Malinois chews on this all the time, and it has held up pretty well. Good option for chewers

Fetch Perfection
Size: Medium (2.5"), Style: Fetch Pack 2
If you’re anything like me, fetch is the ultimate game with your furry companion. The Chuckit! Dog Fetch Ball Medley has taken our playtime to the next level with its variety and durability. This 3-pack of medium-sized, ultra-rugged balls is perfect for endless games of fetch without worrying about wear and tear.
I love how each ball has a unique texture and color, keeping my dog engaged and excited every time. The medium size is just right for energetic dogs, allowing for long throws and big leaps. Plus, the rugged design means these balls can withstand even the most enthusiastic chewers and rough play sessions, making them a great investment for active pets.
However, the vibrant colors can sometimes make them easy to lose in green grass or sandy beaches, but a good game of hide-and-seek with your dog is a small price to pay for such fantastic fetch balls. Additionally, while they’re durable, no ball is completely indestructible, so occasional replacements might be necessary for the most aggressive players.
Overall, the Chuckit! Dog Fetch Ball Medley is a must-have for any dog owner looking to enhance their playtime. They’re fun, durable, and keep both you and your dog entertained for hours. A solid 5-star rating for their quality and variety, with a tiny star lost to their occasionally elusive colors.

great ball!
Size: Medium (2.5"), Style: Fetch Pack 2
My pitbull LOVES these. She is a power chewer and tough on balls and toys and tends to go through them insanely quick. She is still on her first ball out of this pack and its been at least two months. It is a little small for her mouth but she doesn’t seem to mind, as it has quickly become one of her favorites. Not a loud ball and it doesn’t usually make that wet chewy noise when shes going to town on it which is huge for me😂😂 Safe for my pittie so i’d imagine a smaller dog would be just fine.

Border Collie Approved: Easy to Clean, Durable, and Great Bounce
Size: Medium (2.5"), Style: Fetch Pack 2
These are the best balls out there for dogs. These fit great in the chuck-it ball launcher, which we need to wear out my border collie. They fit her mouth properly and, most importantly, do not absorb all the spit or water after a good rain. They are quick to clean off and have good weight so you can let them fly! Furthermore, they bounce well, which is perfect for my dog that likes to catch them on a bounce. The ball is a strong rubber, so should not be easy to chew up. I've used these for years, and the only time I've had to replace them is when one gets lost in the hay field. I highly suggest these as replacements for the common tennis balls.
