Hey everyone, I'm new to the forums. I recently picked up a 1/4in socket set from tekton. At what point should a 1/4in drive set stop? I saw online they make 15mm and a very obscure 5/8. At what point should it crossover into 3/8? Will I regret not having a 15mm and 5/8? I'm a DIY guy and mostly do small engine repair and light automotive repair on my own vehicle. I looked online and I think SK makes a 17mm 1/4, That's just insane. IF I were to purchase these sockets should I go with shallow or deep? Thanks in advance.
I'm in the DIY camp too. I don't think you'll "regret" not having those 5/8 or 15mm in a 1/4" drive. It sounds as if you might
feel your set would not be complete without them, and so in that case you might buy them just for peace of mind, pride of ownership, and confidence that your set will handle whatever you might encounter. If that's the case, I'd buy them for those reasons. For example, 1/4" drive SAE sets typically max out at i/2 sockets. I have several sets of of these in various locations on the farm and truck, and I bought 9/16" sockets for all of them. I added them mainly to satisfy the
feeling that I have that size if I ever need it, almost like completing the sets that the mfrs failed to do. But in all the years I've had them, I think I used one only once, and then it was a matter of convenience at the moment, so I didn't really need it. But it sure feels cool when I open any of those sets and think to myself "Man, I got that 9/16" socket in this set too." The emotional satisfaction is definitely worth having bought them, even though none fit into the case "trough" compartment dedicated to the standard sockets that already fill them.
From a practical viewpoint, I think those oversize sockets would be more like a specialty tool for those rare instances where a 3/8" drive just won't work, like for those specific jobs where you have to buy the specific tool for it. I personally have never encountered one where a 5/8" or 15mm on a 1/4" drive was the only way to fly and nothing else would quite do. I was recently working on a small device on my bench that had a variety of fasteners both hex and hex key. The 1/4" drive was much easier to work with while a 3/8" would have been bigger and more cumbersome getting around it. I had one fastener that required a long shank hex key bit socket, but I only have these longs in 3/8" drive sockets. I just got a 1/4" to 3/8" adapter (which I also have in every 1/4" set) so I could continue to use the smaller, lighter 1/4" ratchet. I can't think of a single instance I've encountered where this adapter would not serve perfectly for using these 'oversize' sockets in the normal 3/8" drive with a 1/4" ratchet--that's precisely what they're made for.
If you go for those bigger sockets, might as well get them in both standard and deepwell sizes. Why not?
