Description

NEIKO presents our 3/8-Inch-Drive Impact Socket Set with SAE and metric sockets! It includes both deep and standard SAE and metric sockets with easy- to-read laser-etched markings for quick identification. Each socket is protected from oil, dirt, and grease thanks to a phosphate coating and is constructed with drop-forged premium CrV steel for maximum life and durability. With a 6-point hex socket design to protect from round off and other damage, each socket in this socket extension set can be used with complete confidence. This set includes extension bars and a U-joint adapter to let you reach more angles on fasteners in tight places. It also comes with a blow-mold socket case that has an individual space for each piece. Secure levers on the case prevent it from opening while you are traveling from jobsite to jobsite. This set includes the following SAE standard and SAE deep sizes: 5/16", 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", and 3/4". It also includes the following metric deep and metric standard sizes: 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, and 19 mm. Additionally, each set comes with one 3-inch-drive and one 6-inch-drive impact extension bar, a 3/8-inch universal joint, and a 1/2-to-3/8-inch reducer. Whether you need this high-quality socket set for use on a housing construction site or for an automotive mechanic job, it will help you get the job done quickly and efficiently for years to come.

Sturdy Impact Socket Set
Size: SAE & Metric Style: Deep & Shallow Pattern Name: SAE & Metric, Swivel
This impact set replaced all my 3/8 drive sockets. After a year of steady use, pounded with impact drivers, both pneumatic and battery, this set is still in perfect condition. No sockets cracked, size markings still readable. The case keeps them organized for ease of use. I would buy this set again, for sure. ... show more

Really nice sockets excellent markings. Excellent condition quality control was top-notch. The case is well. Made the hinge with a good latch. I really like these. Makes it a lot. Easier to keep all my sockets to one place. If you’re on the fence about these, don’t be go ahead and buy them great for medium to light use like I intend to use them for not every day purpose but I regularly wrench on equipment and I trust them ... show more

Great 3/8 impact socket set!
Size: SAE & Metric Style: Deep & Shallow Pattern Name: SAE & Metric, Swivel
As all the other reviewers said, this is a great set. It has everything you need! Each socket has a big white label on it, but they are also engraved with the size in case the white label rubs off. I bought it to use with my 3/8 Milwaukee stubby impact. With 550 ft lbs. of torque, the Milwaukee can put a lot of strain on sockets but these Neiko sockets handle it easily. And for the price, it’s a no-brainer! ... show more

Excellent case, quality and variety
Size: SAE & Metric Style: Deep & Shallow Pattern Name: SAE & Metric
Sizes are stamped/rolled and laser etched. Nice touch. Would have been nice if the etching lined up with the detent pin holes but that's picking nits. Phosphate coated not iron oxide which is nice. Box says "Made in Taiwan". These are CrV as opposed to CroMo. CrV is more brittle and so I'm told the walls need to be thicker to compensate for impact shock, but they will last longer than CroMo, as CroMo will begin to deform with use. Supposedly CrV will shatter, CroMo will crack instead. I've never seen a socket shatter under correct application so, always wear eye protection when wrenching, and take that for what you will. Thicker walls might create clearance issues around certain fasteners. On that odd bolt or two it's likely that clearances are an issue from every angle so I'll be using a extended box wrench anyways. I was willing to give up thinner socket walls for all the other features this set offers. The plastic case the sockets come in gets 5 stars. It has an actual hinge as opposed to more expensive brands which use a flimsy piece of plastic left connecting the two halves from the blow mold process. The handle grip is part of the case, and not separately attached giving it a very solid feel. Additionally it has hinged clasps rather than clips which we all know wear out quite fast from use. All the sockets lay down in the bottom tray and appear to stay quite secure when closed when the retaining foam sheet is left in place. I wanted a socket set that did not use the top lid to hold sockets as repeated removal/replacement of those sockets will quickly wear out the plastic that retains them. The case for this socket set is a strong selling point. It's important to me that I be able to stow this kit reliably in a vehicle or mobile-repair situation and not have the rear hinge let go and dump it's contents all over my trunk. This kit comes with a VERY useful 3/8 to 1/2 impact adapter which I'm sure I'll use on the 3/4"-17mm+ sockets switching between my two guns. Extensions are also of useful sizes and appear quality with minimal wobble/slide on the tool-end square drive and little to no off-axis rotation at the socket-end square drive (meaning they were allowed to cool slowly and properly). This limits an extension doing the ol' whirly-gig and flinging your sockets across the concrete when you tap the trigger on the gun a bit too soon before you're 100% on a fastener. The u-joint socket adapter is a bit on the bulky side, but that should come as no surprise as it's CrV impact rated. IMO it should have been deleted and made room for a 6" or 8" wobble extension OR a small selection of 8-12mm 12-point sockets (for drivelines), and all the extensions should have been wobble. That may be just me though. I wish Neiko or their parent company would consider branching into chrome, because it's obvious whoever puts these sets together knows what they are doing. In any case, I'm very pleased with this purchase and would recommend. I buy a lot on amazon and rarely review. ... show more

A Solid Choice for the Hobbyist Mechanic

As someone who takes on mechanical projects more as a hobby than a profession, I recently found myself in need of an impact socket set for use with my Milwaukee M12 driver. High-end, brand-name sets seemed overkill for my level of use, leading me to the NEIKO 3/8-Inch-Drive Impact Socket Set. This set appeared to offer the balance of quality and affordability I was looking for. Upon arrival, the first thing I noticed was the uneven coating of oil on the sockets, intended to prevent rust. While initially a bit concerning, it turned out to be a minor issue that didn’t affect the set's functionality. The sockets themselves are robust and have so far handled the tasks I've thrown at them with ease. From casual automotive work to various home repairs, this set has proven to be quite capable. The practicality of this NEIKO set is its standout feature. It's straightforward and unpretentious, yet it includes some commendable qualities. The durability, thus far, has been satisfactory. One month into using them, and they've shown no signs of wear or failure, which speaks to their build quality for the price point. While not adorned with the prestige of more recognizable brands, this socket set fulfills my requirements perfectly. It's a practical choice for anyone like me—a simple mechanic who enjoys dabbling in projects without needing professional-grade tools. I plan to monitor the longevity of these sockets and will provide updates on their performance. As of now, they are a valuable addition to my toolkit, effectively supporting both my work and home repair needs. ... show more

The Socket Set That Finally Ended the “Where’s the 10mm?” Era
Size: SAE & Metric Style: Deep & Shallow Pattern Name: SAE & Metric
I bought this set as a Christmas gift for my husband, who owns a lot of tools… just not complete sets of anything. He’s the kind of mechanic who has three versions of the same socket and is somehow still missing the one he needs at any given moment. This set was meant to close the gaps and provide backups for the usual suspects. Mission mostly accomplished. Quality: Right out of the case, these feel solid. The sockets are made from heat-treated chrome vanadium steel, and they have that reassuring weight that says, “Yes, you can put an impact wrench on me.” No thin walls, no sharp edges, no sketchy feeling under torque. They’ve already been used on stubborn bolts without any signs of deformation or wear. Finish: The black phosphate finish isn’t just for looks, it’s practical. It helps resist corrosion and makes the laser-etched size markings easy to read, even in a dim shop or when everything is already coated in a fine layer of grease and regret. The markings haven’t faded after use, which is a small but important win. Functionality & use: The 6-point hex design does its job well. Fasteners stay intact instead of rounding off, even under impact. The set includes both deep and standard sockets in SAE and metric, plus extension bars and a universal joint, which makes this a genuinely versatile kit rather than a “mostly useful” one. Whether it’s automotive work, shop projects, or general mechanical chaos, this set covers a lot of ground without needing extra pieces pulled from elsewhere. Size range: From 5/16" to 3/4" SAE and 8 mm to 19 mm metric, this hits the most commonly used sizes. It’s not a specialty set for obscure fasteners, but it’s exactly what most mechanics reach for day-to-day. For someone who already has tools but lacks organization or completeness, this fills in the missing puzzle pieces nicely. Case & durability: The case deserves a shoutout. It’s sturdy, well-organized, and has already survived a few accidental drops in the shop without cracking or popping open. Everything stays in place, which means fewer loose sockets rolling under benches never to be seen again. Value: At around $70, this feels like a fair price for a 44-piece impact-rated set that actually holds up to use. You’re paying for durability, coverage, and convenience, not just a brand name. It’s especially good as a gift for someone who works with tools regularly but hasn’t invested in a complete, organized socket set yet. Overall, this is a strong, practical set that does exactly what it’s supposed to do. Not flashy, just reliable. Four stars and a solid recommendation for the mechanic in your life or anyone looking to finally stop hunting for that missing socket. ... show more
