These versatile sockets feature a pinless construction that's less floppy than the completion after extended use with 6-point design that offers a deeper hex and inner socket depth while maintaining a mid-size overall length for better maneuverability. Unlike traditional universal sockets that use pins for articulation, the 78344M utilizes a pinless design, allowing a full 360° of freedom for the head to swivel and angle with a longer service life. Constructed from forged Chromoly (CRO-MO) steel, these impact sockets are built for heavy-duty use and backed by Astro Tools' simple lifetime warranty. The set covers the most popular 3/8" drive metric sizes from 10mm to 19mm, with overall lengths ranging from 68mm to 80mm (2-5/8" - 3-1/8").

I own a lot of big brand tools & most of my swivels are snap on branded, gave these a shot & so far so good! Only used a handful of times however for the price worth every bit. 10/10

So I haven’t used these ALL that much but when I have I’ve put them on my Milwaukee 3/8 stubby impact (the new one 2562 model) and they’ve performed well. Mostly used them pulling transmissions and whatnot. The length I find to be just right on these “mids”. Not too long and not too short. I like the slim profile of the pinless design and these have not bound up on me like other cheaper brands pinless design has.

Bought these as my pinned version broke for the 3rd time and figured I would give these a try, so far so good after hammering the 12mm throughout the day no looseness or wear noted, will update review if they fail on me.These are nice when new but don’t last even under low torque, and warranty through the website is almost useless as a replacement isn’t in stock. As well I waited weeks to even get a reply only to be told “it went to spam due to photo” yet that’s what the site tells you to do.

Bought these because I got tired of having to fish a socket with a swivel around a catalytic converter when I'm pulling manifolds to do further engine work, with how skinny the socket is I can put it on a long extension and slip it right where I need it to be. Socket is the perfect length for the nuts on the bottom of GM exhaust manifolds (I work at a GMC/Cadillac dealership) and it doesn't seem to lose any joint durability when I put my bigger half inch impacts on it for the extra bit of torque. Definitely worth the buy, my only complaint would be the storage case takes up more drawer room compared to the shallow swivels.
