Sunex Impact Socket Set Rocks!
[This review was collected as part of a promotion.] The Sunex Impact Socket set #3342 is a wonderful assortment of common standard deep impact sockets. Each socket in this kit uses the 3/8 Drive, taking the guessing game out of which ratchet or impact you need to switch to. The SAE sizes range from 5/16” to 3/4” and the metric sizes range from 8mm to 19mm. Can’t find your elusive 10mm socket? Not to worry! This socket set has 2 different 10 mm sockets AND a handy size chart on the packaging to help you find an adaptive solution. As someone who appreciates a nice set of tools, I am happy that Sunex 42 piece set has 40 sockets, one 3” extension, and one u joint impact swivel. Some companies include the carry case as one of the pieces in the kit. Sunex does NOT do that here! The light gold writing on each socket contrasts nicely with the matte black finish of the sockets making them easy to identify. I experienced positive engagement to each ratchet and impact I’ve tried with these sockets. This socket set includes a lot of value and convenience in an easy to travel package.

quality impact set
[This review was collected as part of a promotion.] After receiving the Sunex 3342 impact socket set we put them immediately into use. We have 3 trucks and 4 cars that we service and maintain. These sockets continue to hold up flawlessly and I would recommend them to anyone looking to add to or upgrade their tools. The case comes in very handy to keep the sockets organized so your not searching when you should be wrenching. The labeling on the sockets is easy to read and is both inked and stamped. overall I must say that the with the quality and features that I mentioned above you have made me a return customer.

Great kit to keep in the car
[This review was collected as part of a promotion.] I've had this kit for about a month now had a motor job coming up was going to use it on that but life didn't work out that way lol I was on my way home from work at 7am and the water pump in my 04 ram went out I keep some tools in my truck and just happened to have this kit in there and it was a life saver so after running around and getting parts I grabbed this kit and got to work it has every size socket deep and shallow that I needed they fit my snap on ratchet and bout my Milwaukee m18 impact and my m12 fuel ratchets perfect they didn't fall off no wobbles nothing did exactly what they were saposta do this kit will now and forever stay in my truck it will be great for junk yard trips as it is in a blow molded case the side walls of the sockets are thick enough that I wouldn't be worried about them breaking or anything crazy like that and the finish is good I don't see anything wrong with it I will definitely recommend this kit to anyone looking for a good cheaper set to keep in the car or keep around for garage projects

High quality tools with a lifetime warranty!
[This review was collected as part of a promotion.] I recently received a 3/8 master set and it’s been nothing but awesome,I use it daily at a machine shop and have had zero problems or issues with it. All the sockets are easy to read and easy to carry around when I need to be mobile. I recently purchased some additional sunex tools and can’t wait to buy some more. I have been looking at the higher priced tools lately but i can’t really see paying triple for the exact same thing! I own snap on,Mac and matco and the sunex tools are neck and neck with all 3. I’d recommend these to anyone,pro or just the average do it yourselfer.

My favorite impact sockets
[This review was collected as part of a promotion.] I received this impact set a couple of weeks ago and love them. They are perfect for 99% of my needs. I mainly used them for driving lag bolts for hanging things like TV wall mounts and for automotive applications. The one place I had an issue was lug nuts but that was due to my impact wrench and not the sockets. I've use the 1/2" version of these sockets before to take off lug nuts so they are definitely capable of it. It's really nice having a complete set of SAE and Metric sizes in both standard and deep lengths. The deep ones are great for longer lag bolts and the standard ones are great for tight spaces.

Good selection of sockets
[This review was collected as part of a promotion.] I have had this for a week or so now very happy with the selection of sockets and accessories

Great Impact set
[This review was collected as part of a promotion.] Received this 42 piece impact socket set about two weeks ago. So far I love them. They came in a nice red storage case. The tolerance of these sockets are really tight so they grip the head of the bolt tight and you don't have to worry about them slipping off. I really love the fact that these sockets are in a 3/8” drive which allows me to use the sockets in tight spaces vs a 1/2” socket which are usually too big to fit. I also like how these sockets clean up easily and still look new.

Best overall socket set!
[This review was collected as part of a promotion.] This socket set is perfect. Has all the sizes I needed for the majority of the work I do. I'm a technician at a Ford dealership. And this socket set works on 90% of the work I do. From simple oil changes and brake jobs to pulling transmissions. Sockets are well built. The swivel is fantastic. Could use one more, longer, extension. But that does not take away from how good this set it. I can easily grab the case and take it wherever I need it. Which is fantastic. Blow molded case holds everything in place nicely. I have Snap-On, Mac, and other big name sockets. These are just as good if not better and cost much less. I absolutely love this set. It will be getting a lot of use.
