Description

The Astro pneumatic tool 78340 SAE 8-piece 3/8-inch drive Nano pinless Universal impact sockets are up to 11% shorter than standard low-profile Universal impact sockets and are made from cro-mo with lifetime warranty.

    • Great tools for a affordable price. And without the lousy pin in the middle
Size: 1/2" Metric Pinless Style: Sockets
If your auto body or a mechanic you need to try these even for 1/2 they work and bend pretty darn good. I picked it because they don't have the pin in the middle. They are durable and work great you can tell its a good socket by the weight of it. It even feels durable. Im just saying they where worth the money i work hard for and they didn't try to break my bank pretty affordable. You can see they wont break easy they like i said have the weight and they are made compact but thick. They get a 10 from me if i could rate them more stars i would. ... show more

    • Good quality 3/8 swivel sockets!
Size: 3/8" Metric Pinless Style: Sockets
The media could not be loaded. Just completed a complete front suspension job at my house, everything from inner and outer tie rods, brakes, struts, rotors, hubs, lower control arm, bushing, stabilizer bar, sway bar link, and the list continues. I exclusive used the Astro 3/8 swivel sockets for most of the job. I really beat the heck out of it with my high 3/8 impact and produces over 500 ft lbs or torque. At the end, they seem brand new, swivel seem to hold in place like original. Compared to the truck brands, these are like 1/10 the price! If I had to start over, I would exclusive get the Astro sockets. I already own a few of their sets, and the quality of their sockets are great. I found out about them from the torque test channel, and they rated Astro as one of their top picks. Easy to put into a ratchet or impact and works well as it fits into most spaces! Great buy and good quality! ... show more

    • Very nice!
Size: 3/8" Metric Pinless Style: Sockets
Just got the two 3/8 drive sets yesterday and they already saved me a bunch of time today. They held up just fine to my Milwaukee compact impact wrenches. Will be ordering the 1/2 drive sets also.

    • Great buy and looking to purchase some more in the future
Size: 3/8" Metric Pinless Style: Sockets
I use these quite often in tighter places where you don't need depth in a socket. I use them a lot on brake caliper brackets and shock bolts and things of that nature that don't have a nut on the other end. Great set to have and I own a handful or so of Astro tools and look forward to purchasing more in the future without hesitation ... show more

    • Great tools, real problem solver and they were spot on correcting the 17mm issue
Size: 3/8" Metric Pinless Style: Sockets
Update: After discovering the 17mm was actually a 16 the one time I really needed the 17mm I was genuinely not happy. I had not ever reviewed these as I really hadn't found a whole lot of reasons to use them. The 15mm comes in clutch for working on Chevy trucks, particularly the AC compressor, and they came in super handy for getting the bell housing bolts in (aftermarket without the stud and secondary nuts) on the same but mostly they just sit in the tool bag waiting for a problem to solve. I had one on the exhaust on a Infiniti G35 which is just an evil car to work on and lo and behold the 17mm didn't fit. After I figured out another way around it and had left the review I went ahead and called Astro the next day and they were aware of the problem and were quick to send a replacement and were genuinely easy to work with. Its not every day someone can turn you around so seamlessly that I came back and updated my review. Great company to work with and genuinely good product that solves problems. Original: I generally like Astro tools, and this one is pretty sturdy pretty durable and a category of tool that I love, I have quarter inch chrome gearwrench sockets with a swivel and a mix of Mac, Sunex and Snap on etc half inch swivels, so I bought this set to have 3/8. I've not had much occasion to use them until I needed the 17 mm which is labeled as 17 mm on both of the socket portion and the bottom portion but sure enough it's 16 mm, so the first and only one I've needed was absolutely useless. Not sure I would recommend these to anyone unless you really want to take the time to check that everyone is the size that is printed on the damn socket. ... show more

    • Good
Size: 3/8" Metric Pinless Style: Sockets
I haven’t used them yet, but they seem good in robust. I I measured them all with Verniers and they were fine.

    • Buy These
Size: 3/8" Metric Pinless Style: Sockets
Use them daily at a dealership on 3/8 and even 1/2 air impact and so far they have no problems at all, still smooth and snug. Only downside is the labels very easily rub off when spinning against stuff but that’s nothing to care about considering the important stuff. (the actual tool quality)
