Very good quality. The first bit I used was for a stuck manifold plug that someone had overloaded into the engine intake. We had to use a large jackhammer to free it and although we pressed hard on the chisel it didn't come loose.

I have been using Sunex brand power sockets on a daily basis for many years and have never had a problem. When my colleague brought this set one morning, I knew I had to have one for myself too. I still kick myself for not looking for and buying something like this sooner. These are my new outlets, which are really hard to reach.

Holy smoke, these are tough things! I was concerned about the quality and I was wrong! I had a stuck caliper on a Chevy truck that required one of these sockets. I used a little cheater and at one point I thought I was going to break the ratchet! Even at the tip of the spout there were absolutely no marks after use, it was just rubbed clean! The case is very nice, thick not thin, and the lock works well!

I bought this item to use on my four wheeler after selling lug nuts. A 12mm Allen key was required, this set was available with both SAE and metric sockets at a reasonable price but proved unusable for the intended application as 12mm would not fit. He was too big. I know it was a 12mm nut because I ask the manufacturer. I haven't used other sizes so I don't know if they will fit or not, but 12mm definitely won't. I haven't contacted the seller yet, but I will soon.

Harbor Freight does not sell short sockets. This set of sockets from Sunex came to the rescue. Exactly what I needed to loosen the M12 hex drain plug from the center transfer case on an Audi A6 C5. This socket also helped me loosen an M18 hex drain/fill plug on the same vehicle; Clearance was a major concern when using Harbor Freight outlets. Chances are this Sunex set is all you will ever need when it comes to a hex head set. Buy it immediately for the first time.

I received a Sunex 3646 that was not wrapped in the traditional cardboard lid with plastic wrap. I opened the plastic case and found that most hex screwdrivers were not marked with smudges. The 19mm hex lacked a lot of paint. I assume that it is a returned and used item. If I pay for a new product and get a used one, I'm not happy. The Sunex product seems good but I blame the seller for not stating that it was a returned and used product! So yes, the seller only 2 stars! RS

Very happy with this purchase. Sunex make very strong, high quality impact sockets and these hex screwdrivers are no exception. The short profile is ideal for those tight spaces. IE caliper bolts. They have been used many times both with a percussion pistol and by hand with no visible signs of wear. The hexagonal tips are precision cut, ensuring reliable engagement with fasteners. The drive head is also precision cut, well suited to other tools with minimal "skewing". Sunex has quickly become…

Works great I've worn them seriously so far. I had to use my 3/4 x 10mm percussion gun to remove the drive motor from a Bobcat at work. He immediately loosened the screws. I bought a set for 5/16 but ended up using way more sizes than I wanted. I think this is my pick because it's so compact and easy to carry on a bolt as I'm not very good at guessing what size which hex head is. They're short on some things, but for the price, they're worth having in a toolbox.

I really like this little set. And most importantly, they are very durable and do not twist or deform. You'll find there are others from other companies that can't handle a lot of force. These will not. Sunex is always a good product. I would happily buy anything they do. You are very innovative. I used this set to tighten the differential cover and I liked that it was the correct size hex for the drain plug and filler plug. All my life I've settled for cheap tools, and now that I'm an antique…

I love this hex screwdriver set. I'm an electrician and I terminated 750 KCMIL wires close together in spade lugs. I had to buy a Husky ratchet because my cobalt was too thick, but I came up with a Husky ratchet and these short hex screwdrivers to tighten the eyelet screw to the wire. It was sooo beautiful. until my partner dropped the ratchet. I don't know how but the driver went off the ratchet and hit a 4 inch pipe coming out of the ground. Not sure which tube and I couldn't fish it out with
