This is a set of Bergen Aviation spanners, I actually bought these because I was after some
long series spanners and unfortunately I couldn't find any, but these actually popped up in a search
on eBay and I have to say that these are absolutely fantastic.
They are a double ring so you have a ring on each end and these are also straight.
Now I have searched to try and find out about Bergen and I can't really find out a
lot about them, so I was a bit dubious to begin with of the quality of the
spanners. Obviously if you in America these will be known as wrenches. The actual
sizes that I needed for work where 19 & 24 mm so this set has those in.
To be honest I am actually surprised at the quality of these the actual quality of
the chrome plating on them is very good and I have to say I've been using these for
about two years on site with absolutely no problems. Obviously because they are
ring spanners there are certain jobs where you can't get them on sometimes you do need an
open-ended spanner but because these are so long you do get a lot of leverage. So
I'll just get that one out which is the 19 mm on one end and 18 mm on the other and
that is a standard combination 19 mm and you can see that you've got maybe 6
inches extra leverage when you are tightening or undoing nuts and bolts. So
these are really advantageous and they're much better than long series
spanners because they are even longer than that. The ones that I use most of
the time is 19 mm which would be M12, and 24 mm which would be an M16. As you
can see these have been used quite a lot at work in a tough environment
and there is absolutely nothing at all wrong with them. They are still working
perfectly well. So I actually searched the Internet and there were a lot of people
saying that Bergen are not such good quality but to be honest I found them
absolutely superb they are much cheaper than Teng or something like that and the
quality on these is absolutely superb. So I do apologize in advance
because you're probably going to go out and buy a set of these and it's going to knock
you back about £35 for the full set. So the sizes in this kit are 8 and 10 11
and 13 14 and 15 16 and 17 18 and 19 20 and 21 22 and 24. So to demonstrate the
advantage of these I've got an M12 bolt which is in a tapped hole in this 10 mm
steel plate. We are going to put the ring end on there and I'm going to ensure that is tight.
I can tell you now that is very tight. Because of the length of the
aviation spanner you obviously get a lot more torque on this so I can simply put
that on there and I could simply push down with one hand and easily undo the
bolt. So it requires a lot less effort when you are tightening and undoing nuts
and bolts. Another advantage of these spanners
is that because they are straight there is less chance of them slipping off if you
need to lock them up against something. There is one particular machine that I
work on and you can't actually reach both sides of the machine at once so I tend
to lock the spanner up against a shaft and the shaft is round and is stainless steel. Now with one of these spanners I can
quite easily lock the shaft up.
It is quite a large diameter maybe two inches and I can simply put the
spanner on and it will actually hold itself against the shaft. If you get a
normal spanner because the end is angled when you put that on there and you
tighten that up because it's angled it does tend to push it away so if you try
and tighten it as tight as you can get it the spanner actually slips off. It's
really hard to recreate it but I'm just trying to explain this the best I can at
home hoping that you will understand what I mean.
So because of the angle of the spanner when you try and get the nut on the
other side of that really tight it tends to slip off and the spanner falls off.
But with the aviation spanners because they are straight you can lock them up
perfectly well on something like that or against
the flat surface and there is less chance of the spanners slipping off. So
that makes them really useful for me. Obviously that may be a disadvantage for
some people it does mean that when you are tightening nuts and bolts there is
potentially a trapping hazzard and some people do call straight spanners like this
knuckle breakers. But for me these have been absolutely fantastic and I
really wouldn't hesitate to buy another set of these. There are jobs that you do and
there are 10 times better than a traditional ring spanner or a combination spanner.
So I would just like to point out that I'm not affiliated with Bergen in anyway I'm
not actually on commission but these are just one tool which I found really,
really useful and they have been a very good quality spanner.I hope you have
