Another gem. As a time served mechanical fitter I knew which way to use an open ended spanner - but I had no idea why! That's my bit of learning for today, don't need to learn anything else until tomorrow!
@@ToTheGaragealthough you aren't wrong, you forgot something. You always pull to yourself. So as not to slip and bash your knuckles. So you set the jaw based on your description of forces, and pull.
This is not a good advice. He’s completely wrong. This is only a demonstration on how to improperly use a range. The torque test channel did an imperial test proving this is a myth perpetuated by adjustable wrenches and poor technique.
@@coryulrich6489 Torque Test Channel has no videos on adjustable wrenches. If they have one on using an open end wrench backward I couldn't find it. They have one video that mentions using one discontinued ranch backward. But they come to no conclusion.
Shocking how many people either don't know this or don't believe it. So far you are the first of a dozen you tubers who knows why it's better to use a crescent wrench in the correct direction. I don't see why these people can't tell the deference by simply trying the damm things both ways. You can literally see them rounding off the nut when used the wrong way. If you look at the angle of the handle it appears to be pulling the wrench off the nut when used the wrong way. Thank you so much for laying it out in black and red.
what no comments so far, good one John, must say from my point of view IF IF I can get the ring end on thats my favorite choice,but what you say is very true and I bet most people also do not realize is that the length of a standard spanner help dictate the torque than can be put on a bolt, which is why the spanners get longer with the size increase.
Nice. Wish I had thought to that when I was filming. Wait for a week or so and I will pinch it though🤣 Must admit I was bracing myself for a lot of negative comments about teaching people to suck eggs. Despite knowing loads of folk who you would imagine would know, have never been shown this stuff! I will hold judgement for a few days though. If i don't get too much abuse I have loads of these little facts, and if i am honest, emergency bodges.👍👍
👍. Yet amazingly rare knowledge these days. The decline of formal apprenticeships means many people are never taught engineering fundamentals, they leap straight to cad cam programming and 3D printing.
Was watching a Ytube by a Massey Ferguson mechanic and his spanner slipped several times - I thought 'My Gosh, how come he doesnt know this?' Anyway, next video up was yours. Now my dad never exactly told me 'why', but logic still somehow thought that holding it the correct way would hurt my hand more if the spanner did slip - but you showed by explaining the force direction why that would not be so ...thank you.
The demonstration of the “right” and “wrong” way to use an open end spanner or wrench is not correct. In fact, that end is designed to be flipped over and used either way. That is why it is set at a 15° angle. It allows a nut to be turned when there is restricted space to swing the wrench. Some people might think that it is designed to be used in one direction by comparison to a “Crescent” style adjustable wrench, which is intended to be used in one direction only. In that case, the directionality has to do with the movable jaw. Using the wrench in the correct direction tends to force the movable jaw against the body of the wrench, keeping the assembly tighter.

An interesting video as usual John. However, I must say that in 55 years of spannering I have never had a problem with open-ended spanners slipping off the nut. Perhaps because I always maintain a steady pressure along the spanner towards the nut. I've had too much experience of open-ended spanners rounding the flats but that's why I always try to use ring spanners or hexagon sockets and avoid open-enders and, in particular, adjustable spanners like the plague.
Closed and 6 sided is always best 👍 but sometimes you need the access. Im with you on the adjustables I own several as I like new toys but other than having one for an emergency box where you only have space for one spanner, I rarely touch them. There is One form of adjustable spanner that actually works. It doesn't slip in its setting and the jaws are always parralell. I do own one and will have to find it out and share. Its a WWII Adjustable German U boat spanner. You cant avoid to be rounding off heads in a sub!
Interesting analogy. TBH the open end for me is only there when i can't get the ring end on a nut or bolt head..... or to use on pipe fittings. Open enders damage the corners of the bolt or nut whichever way you push or pull it. Good video though. Cheers ;)
another thing I discovered (and yes I should have known better) thanks to James May the longer the screwdriver you use the less chance you have of buggering up the slot. :)
Agreed. The hierarch is Six sided ring spanner or spanner 12 point socket or ring spanner Split ring spanner (brake pipe spanner) 2 sided or open ended spanner Adjustable spanner pliers 👍
Well just dandy if your dad or grandad - explained this to you when you were a nipper. But for the rest who say: *_'Oh yeah, of course I've known about this my whole working life'_* ...bull. Deep down, you know _you're only lying to yourself._ So just swallow your pride and admit it - that in all those years on all those jobs of using open-ended spanners - that you really didn't know this.
Interesting theory and demonstration. It does make sense, but I too have never had an issue with this - I position as needed according to accessibility. I could see this being useful on large fasteners tho 👍🏼
Hi. Thanks for the comment. It does not affect how likely you are to slip as in round off the nut or allowing the spanner jaws to splay. (This is what the torque change tested. It affects the likely hood of the spanner slipping OFF the nut. ie moving towards the user's hand. The cause of many a grazed knuckle.
Another gem. As a time served mechanical fitter I knew which way to use an open ended spanner - but I had no idea why! That's my bit of learning for today, don't need to learn anything else until tomorrow!
Thanks Alan. I will try to come up with something every week or so.
Tomorrow may be pushing it🤣

No problem Rob. Thanks for watching
Excellent simple lesson, thanks.
Glad you liked it!
Best tutorial and explanation so far, like it, other u tube channel so suck in this spanner thing
Thanks
Nicely explained John
Thanks Terry👍
Nicely explained - as always. Nice spanner set you have there. I must have at least 5 different brands of spanners in my mixed up toolbox!
Ive got those as well Mike. Its just my Sunday best I let everyone else see🤣
@@ToTheGarage happy Sunday everyone lol
wish someone had told me this before! Well done.

Nice work boss!
Appreciate it!
If you noticed one side is bit longer than the other side. larger end should be direction of the force applied.

Thanks for posting this. The torq test channel proved what you've said to be correct. I was here to basically said what you did.

Although that might not be the intention of the spanner head angle, the logic of what he’s saying still stands
So many mechanic's don't know this. I knew at 7 yrs. old and my son has known since the first time he picked-up a wrench in my shop.
U should do a video on when to use which type of spanner

Hi John,
Back to basics.....bet a fair proportion of listeners USE their spanner so correctly, but not WHY.
Well done sir.
Thanks Harry. I was a little nervous about sharing this sort if stuff👍
@@ToTheGarage another documentary? Lol
Great video
Glad you enjoyed it
Great Tip, but does this work on U.S. left hand "Wrenches"?
Only if you stand at the other end of the 'Wrench' 🤣
Watching right after spoiling a bolt 😅😅
Always the way👍
Thanks, mate!
You're welcome!
Wow, I didn't understand how much there's to it. Thanks
No worries!
another thing I discovered (and yes I should have known better) thanks to James May the longer the screwdriver you use the less chance you have of buggering up the slot. :)
Great tip! Yes the angle you misalign it through reduces👍
Just use the boxed end for breaking bolts loose. The open end is better for Supply lines or double nuts where a boxed end can't be used.
Agreed. The hierarch is
Six sided ring spanner or spanner
12 point socket or ring spanner
Split ring spanner (brake pipe spanner)
2 sided or open ended spanner
Adjustable spanner
pliers
👍
Well, you could use the closed end portion of the wrench vs the open end.
Very true. Most folk will be able to use the ring or box end of a spanner without nstruction👍
The bed is a triangle double with the right down and left top. Thanks john

I've watched this several times but I still have no way of remembering which was to use a wrench.
Closed end for breaking nuts, bolts loose. Open end for once there loose, otherwise you will round off nut or bolt with open end.
👍
Well just dandy if your dad or grandad - explained this to you when you were a nipper.

What's a spanner?
Some people can poke their eye out using a spanner...
Ha Hah🤣. Its funny because its true.
Too funny 🤣🤣🤣🤣
bold of you to assume i own a spanner
Now go try and get your wrench to slip off,
No difference
Huge difference Glen!
Sound logic
Why does one need to watch this upside down?
I knew since I was about 14 years old
This is common sense everywhere in the States except blue states
😁
I don't believe this to be accurate information see torque test channel please. He shows you it doesn't matter as far as slip.

Only very naive people will believe this nonsense…
