Proto sockets

[martin666]

Got this set of sockets today, as I took them out of the box, looking down at them I noticed that there was two of the same size ( ended up being 16mm ) when I pulled the extra one off the rail I saw that it wasn't stamped at all, nothing no name, no size, nothing. Least it wasn't painted inside hahaha

Had a similar situation with S-K. I assume it's caued by being the same as 5/8" until they stamp the size on them.

It isn't same. 5/8" is equal to 15.8 mm. A 16mm socket would slightly oversized.

Glad you can laugh about it. Some people in the past wanted to get up a lynch mob when mistakes happened.

What size was missing? 18 or 19mm? Which seller and are they going to make good on it?

I guarantee they use the exact same tooling and blanks

Quick google search shows 15.88 mm.

5/8 = 0.625"

to mm 0.625x25.4=15.88 mm

It's .005 difference. also never needed a 16mm socket

5/8" = 0.625
0.625 x 25.4 = 15.875

1 mm = 5/127" = 0.0393700787"
0.0393700787" x 16 = 0.6299212592" = 15.9999999836.

My top calculation is the correct conversion. Where you got confused is that you calculated from 5/127" (0.03937") straight into 16 (x16) and then across to mm (x25.4). You completely ignored the 5/8" (0.625")
All you did was say 1 mm equals this, and 16 of this equals this, then convert to mm. Basically you took 1 mm, converted it into inches, multiplied it by 16 and then converted it back to mm.

PS. The google search shows 15.88 because naturally when you round 15.875 it goes up.

Too much beer

They still are so close I doubt they actually use different tooling

The conincedence is too much having the same issue with a different brands 16mm deep socket

18mm was missing but I knew that when I bought them, . The blank socket is an extra 16mm so no harm done. Happen to have the missing 18mm, so I'm happy with the set. Sockets are the usual Proto quality and I have no complaints at all. Only mentioned it because I had never seen a blank name brand socket, am definitely more amused than anything else, even if it wasnt an extra it wouldn't bother me. Still perfectly functional and doesn't take a brain surgeon to remember the 16mm is the unmarked one. Even though I suffer from the common OCD most here on GJ do too, I limit it to having at least one of everything ( 6 point, 12 point, shallow, semi deep, deep, swivel, impact, etc. ) . been swinging wrenches for 40+ years and have still yet to look inside a socket, or ***** about a scratch here or a nick there, and yes 90% of my tools are truck brands or top tier American made, but understand that they are tools and exist only to get the job done and make me money . As long as they do that I have no *****

I wouldn't be so quick to say that. I can't speak for Proto but all my other brands a 5/8 socket will not fit on a 16mm fastener. All of my sockets in 16mm and 5/8 in the same set are different. While I haven't gotten out the calipers there is a very noticeable fit difference between the two sizes on the same bolt head.

Just to add to the peeing contest on the metric and SAE socket sizes, I thought I would mention off memory a 3/4" SAE socket and a 19mm metric socket are about the only sockets that interchange. There might be others but the 3/4" and 19mm are the only ones I can quickly think of.

 

[General Geoff]

22mm can be used as a super tight fitting 7/8" socket. I do this on my truck's lug nuts.

I have to agree with you, before I came on here I had never looked inside a socket except to wipe grease and dirt out of it. I started messing with go-carts and minibikes when I was around 10; worked in service station in my teens have been a diy'er (heavy at times) since then - actually pushing 50 years now.

And I also have to break the GJ OCD addiction. Last year I had to buy the 4.5mm shallow and deep 1/4 drive sockets. Why, I don't know since I never used them before and probably never will, but simply because they exist.

Yep, sounds like the "I have to have one of everything" kind of guy.

5/16" and 8MM pretty much interchange, and I generally find 5/8" and 16MM to interchange also.

7/16 and 11mm 9/16 and 14mm 19/32 is basically 15mm and 13/32 can be used for 10mm but its 10 thou off.

but you dont need to use a 7/8 when its really 22mm
over time it will round the 22mm lugs off.

at best you are going to have to wiggle the 7/8 socket off the 22mm nut every day of the week. it will get you by and a lot of folks at tire shops do it but it kills the lugs
