has anyone got a metric spanner set model?

[stephengibson76]

Grabcad have a nice set but they are not standard length or they are a dumpy set, we would like to drop them into assemblies to make sure we can get to fixings

I didn't think there was a set standard for length and exterior of sockets and boxed-end spanners (wrenches for the non-British audience). The better quality tools will have a thinner wall on the sockets and boxed (closed end) for the spanners. 6-point and 12-point closed end spanners will have different (wall) thickness as well. Impact sockets will have a different wall thickness from hand-sockets as well.

There isn't even a standard to force you crazy British to call it a wrench 🙂

Open end wrench/box end wrench 

There are some head "clearance" standards (based on a composite study of commonly available ones)  I guess in the machinery handbook from the SAE aeronautical drafting manual... nothing for metric in there but this guy has done some work... http://www.roymech.co.uk/Useful_Tables/Screws/Head_Clearances.html

This is my definition of a "spanner wrench".

Maybe cbliss.com has what you need.

I wouldn't put that in the Boot.

I am looking for spanners or combination spanners, (wrenches are for plumbing ...  see picture below.  They do come in standard lengths, theoretically you tighten each fixing with the same force, (human power) and the larger the spanner, the longer the lever hence the correct torque for the size of bolt you are fixing, (this is my understanding anyway, hand tight, then ****)

I could always go to the workshop and measure.  We use impact sockets for our socket sizes as they are the largest we would put on a fixing

thanks, a useful table

[stephengibson76]

thanks, cbliss was my first check, dont know why I missed that one, looks pretty close dimensionally to the spanners we have in the shop

[stephengibson76]

the **** was the technical engineering term "n i p" as in n i p it tight

just a censorship test
