Who sells Spanners?

I remember using an adjustable spanner on a nut when my foreman walked past.He asked to have a look at the spanner,when I passed it to him he threw it out of the window. I then had a long lecture about how the spanner for a 1/2 BSW is marked 1/2 BSW and that is the tool you use. Metrinch (what a stupid name) are a vague copy of the tools designed to work on deformed nuts and bolts, the fact that they can be used on various nuts and bolts,similar sized but difeerent standards is coincidental. There are a few instances where (once again by coincidence) fittings are within a few thou of one another 3/8 BSW and 5/8 bsw , 18mm and 28mm for example) and the two sockets or spanners are close enough that they are virtually interchangeable. This has however been taken to extremes by some of these so called universal tools,I have seen a socket marked 1/2 AF,13mm,1/4 BSF which diod a pretty useless job of fitting any.
Each to his own,but I heeded my old foremans advice and have owned and used four sets of sockets and spanners, BSW/BSF, AF,BA and to my shame Metric. I've also followed his lead and thrown a few out the window too.
I've sold tens of thousands of tools over the years,each one designed to fit one size of nut and to fit it correctly,I've also sold hundreds designed to fit chrome plated,brass or alloy fittings or ones that are rusted and/or damaged. I've never sold one that was intended to do both.

It doesn't, make sense to compare the metrisch tools with an adjustable spanner. If you compare these then you clearly don't understand the basic principle's of metrisch tools. I hear you say that you have sold a lot of tools but no technical explenation why metrisch basic principle's do not work. Unstable load could not give an explenation either. He only said something about certification.

Then Peter, you need;
http://sidchrome.com.au/product/13-piece-pro-series-geared-spanners-set-af/
"TORQUEPLUS™ FASTENING SYSTEM
Apart from allowing extra torque, TORQUEPLUS™ also reduces the risk of fastener rounding, provides a greater opportunity to turn worn, rounded fasteners and meets aerospace specification."
The above explanation of their torqueplus system is from their website and is basically the same concept as metrinch where the loading is applied to the flats of a hex rather than the corners.

If you are into selling tools, i can understand that you want to sell as many tools as possible and not looking for tools that have more applications
Still haven't seen an explanation from you why an "universal" tool like the Metrinch isn't a good tool. I don't use adjustable spanners either and only want to use proper fitting tools but the Metrinch principle works very well on aluminum, chromed and rounded (damaged) bolts and off course on all standard bolts and nuts
Scott, that looks nice. Another item for my Christmas wish list..........

Snap-On has the same thing with their Flank Drive range. From their catalogue..
Flank Drive Plus wrenches feature a patented open end design that delivers up to 62% more turning power than conventional open end wrenches and are available in sizes from 7mm - 25mm and from 1/4" to 1-3/8". Snap-on Flank Drive Plus wrenches deliver more power than anyone ever expected from an open-end design. The box end of Snap-on wrenches features our original famous Flank Drive wrenching system that grips on the sides, away from the corners and helps you turn the most stubborn, and even rounded fasteners. With Snap-on Flank Drive Plus wrenches you get sure-gripping performance at both ends of the wrench.

The vast majority of my spanner work is in AF Inch sizes, so I am going to use the chart below to illustrate my point. Seeing as Metric spanners are also measured as "AF", ie ACROSS FLATS then, taking into account manufacturing tolerances for both spanners and fasteners, the only really interchangeable sizes between AF and Metric will be the 9/32-7.1mm, 7/16-11.1mm, 9/16-14.2mm (at a push),3/4-19mm,7/8-22.2mm (again at a push), and of those, ONLY the 19mm is able to work as a 3/4", the rest can only be a METRIC spanner working an INCH size, which means that I still need to have the relevant INCH spanners in my box to be able to work.
Any other sizes will start to grip towards the corners of a nut as opposed to ACROSS the FLATS, a-la Flank Drive or Torqueplus, and that migration towards the corners will increase the risk of slippage and rounding off of worn or really tight fasteners.

Strong opinions aside, I think that the crux of the utility of Metrinch/Flank Drive tools lies in good workshop procedures, after you have employed them.
A properly fitting, correct size spanner is best but these 'alternative' tools will assist in the removal of a damaged nut or bolt
and therefore have some merit even if the nut/bolt head is further deformed in the process.
The essential point arising is that a damaged item should never be re-used, a new correct size replacement is needed.
Sadly, in the real world, people (ie.me) do run a file over the flats and re-use, digging a pit for the next time!
I don't do that sort of thing now, but in my unthinking youth I did some truly horrific bodges just to get a car back on the road.

I think that this discussion has derailed for no serious reason.
I have quited a long long time ago trying to enter into heated discussions with anyone that i obviously disagree with.
Anyone is free to have its own opinion, and be responsible for the choises he makes for himself every day.
What is the point of trying to persuade someone else for something, anything? In an internet forum for God's sake!
Grow up you lot!

For my part, I am not getting hot under the collar. I was merely laying out my point of view.
For what it's worth, I actually bought a set of the one-size-fits-all sockets this weekend to be able to get a socket that could drive a tap in a recessed location.
My tool use preferences are merely my choice, and I would never expect anyone to follow, nor dictate that anyone did while outside the hangar at work.

Metrinch - I must have every size of socket and spanner they make and although I don't use them on 'good' heads, they're invaluable for where the right tool size no longer fits a rusty/corroded/damaged one.
The only downside is that sometimes nuts get jammed in the tool and have to be hammered out so need to be careful not to hit the spanner/socket.
