Ko-ken 3/8 Sq. Dr. 6 piece Z-series Universal NUT GRIP Socket Set

Pinless Universal Design

An ordinary ball type universal join has a structure with a pin type joint. Ko-kens universal joints are connected with mutually engaged hexahedrons. This connection disperses the load across whole outer circumference. The same durability is obtained with this design in comparison to the pin-type.

Nut Grip Technology

Our nut grip sockets are unique to Ko-ken and truly a revolutionary way of approaching this type of socket. Our fastener holds nuts and bolts in place without the use of magnets. Our system is built with a spring ring and ball bearings on opposing flats. When a nut or bolt is in the socket the ball bearings push out on the springs holding the nut/bolt in place. Our nut grip sockets can completely change a mechanics efficiency. If you lose a nut or bolt inside of an engine it can be quiet the headache to retrieve. With nut grip sockets that dilemma is completely eradicated.

Love this version of Chuck It beyond all before
Size: Mini
I had the longer bendable Chuck It before, well several, which broke down. They finally wouldn’t’ release the ball. Not disparaging Chuck It. They have been my furry puppy's favorite thing ever. I am grateful. But what I like and think is intuitive about this smaller design is 2 things: 1. I can do a more dynamic throw. 2. There are circle holes in the Chuck It Ball that come with it that I think allow for easier release and the ball can go father. Just my two cents.

Still Good to Use in a Pinch
Size: Mini
Love the Chuck it brand. This collapsible one is not my favorite. Everytime I chuck it, the orange lock does not stay in place. Plus, in my opinion, it doesn't have the oomph for the distance like the other medium ones. Still good though

Excellent product and my dog loves it
Style: Classic, Size: 26in
I love these toys almost as much as my dog! It makes throwing a ball over and over much less straining on my shoulder and also allows me to pick the ball up without getting slobber all over me. Chuck-it products are high quality and they're the only ball I will buy now- it's my dog's favorite!

Solid, Quality Construction at a Value
Style: Classic, Size: 26in
It's amazing how much fun my new puppy and I have been having with a single, vacuum-molded piece of plastic. I have a 4mo named Walter and getting a Chuckit® was always in the cards. 1: I didn't know how cheap they were, and 2: I didn't realize how much fun it makes fetch. Really small things like being able to pick up the ball with the Chuckit® without having to bend down was so surprising and makes fetch last longer for both of us. Another tip is that I had watched videos where they say the throwing technique is sort of a punch, or whip action; where you sort of wind-up, throw, and then jerk your hand back (like cracking a whip). I started doing that and it was fine, and working without problems. But then I thought, "I'm just going to launch this with one continuous movement". And WOW what a difference. If you have the space (a big field, basically), you don't need to modify your throw to a punch or whip type movement. Just launch it like you're casting a fishing pole, and end your motion with the Chuckit® pointing directly at where you're trying to throw it. The ball naturally flies out at about a 45 degree angle. High and far. You don't need to overthink it. Additionally, if I'm in my backyard (fenced with neighbors all around) and I can't go high and far, I just side-arm it. And the ball releases on it's own. No need to whip. Looking forward to my Pup growing up so we can play longer. Love this thing. Oh one more tip from my brother– he says a lacrosse ball fits perfectly in these things too if you have a dog that wants to destroy your tennis balls. Lacrosse balls are practically indestructible. Just make sure not to launch it on any surface that will bounce, or you'll never see it again. I'd buy this again in a heartbeat. For the price, stop thinking about it, buy it, and go play with your dog!
