Snap on sockets/wrenches, are hands down best fit on any bolt head. Look carefully, to see if you have cracked the socket . Maybe a hair line crack right at the very top of the tool. That is about the only time I have problems or, I have had to replace a few that just plain wore out from years of use .
When snap on's "flank drive" first came out. I was hesitant to replace thousands of dollars worth of wrenches and sockets just to get the newest gimmick.
I had a 12 mm bolt on a Honda, that was totally rounded, and I was fighting it when the snap on man came in . I tried every socket and wrench I owned, and had that bolt totally rounded off .
I told him, that if "flank drive " removes this bolt, I will replace all of my tools with it right now. I ate my words that day, and went right back on the easy payment plan.

Those lug nuts rust under the chrome acorn cap, and swell . I see it all the time . Chrysler 19mm, and 22 mm , I have to pound on a 20 mm, or 7/8" socket to get some of them off
Takes me 45 minutes to a damn state inspection, because I have to pound the sockets on , then take them over to the vice, and pound the lug nuts back out of the socket . grrrr.

Some data points for look 171 when he gets off his a** and measures some things !

I measured a lot of my Snap-on tools. 6 Point sockets in the size range discussed averaged between .20 - .35 mm larger than the number on the tool. That makes a 14mm socket 14.20 - 14.35mm between the flats.

The size variance is directly related to the amount of use i have subjected them to. A size that was rarely used consistently was about .20 mm larger than it's labeled size and the heavily used ones were consistently .32-.35mm larger than labeled size.

I have never had any of these slip on a good fastener regardless of their wear.


Randomly, i have a first gen 4Runner in the shop now and i measured 14mm Toyota bolt heads at 13.95mm across the flats. No problems removing those with my 14.27mm 6 point Snap-on socket.

Wait till you start taking out the phillips head screws on that 4 Runnner.
Those screws are JIS, Japanese industry standard, and a Philips will strip them out.
I ended up buying some JIS cross points for my 88 Hi LUX, they work for both cross points and phillips.

Did you talk to the fooking guy on the snap on truck?
Get a large tool box and put everything in there.

With a key.

Here is the master key for motorcycle covers:

And thar you go:D

The Range Rover lug nuts are the worst....

Finally got off my ass to measure the sockets and work got my kid to do some more work on it. The dimensions on the both socket seems to be dead on according to some of you.

Oh, pics forgot them.http://forums.pelicanparts.com/uploa...1594526501.jpg

It must be the JIS bolts. I have never encounter them working on older Japanese cars but then again, I haven't worked on cars for over 20 years or work on them enough. The sockets are .3 or .4mm over.

Tell me more about these damn JIS bolts. What sockets or wrenches do you pros use on them?

Unsure where the hand tools from Snap-on are made, but the tool boxes are made a few miles from my home town. made in Algona Iowa.. Employs a few of my friends.. so I always root for them

I think you need to get OGV profile sockets for the Japanese rigs:

Would that eventually eat into the head of the fastener causing it to no longer grip the hex area inside? I realized some of the bolt I wanted to take out has the ever slightly rounded corners. They aren't stripped, factory.

got a close up pic of the bolt?

Can you measure a bolt head ? The ones i just took off this Toyota also have radiused corners.

For brand new sockets, those are definitely a little larger than mine.

A good quality 9/16" six point socket could work better if your 14 mm is slipping..

Be sure they are 100% engaged, i.e. hammered on.

Here's a couple of vids of how much this socket moves. That's too much and if the fastener is tight, it will strip. There are a couple of bolts up front near the radiator.

Dang it, file must be too big. I don't know how to post video?

Craftsman. They fit Toyota trucks/suvs when others do not.

I'm a Snap-On fan. My 1/4 drive ratchet ate its drive gear. I met the Snap-On truck at a local garage, and it was fixed in five minutes. So much easier than any return to department store.
