The Mega Fuse holder I recently bought has a bolt centre to bolt centre on +/- 52mm not 50.8.
As a result the fuse will not fit on without either re-drilling the holes in the fuse or forcing the fuse down which I suspect will break the fuse ( i do not want to try this).
Since I only have one fuse holder I have none to compare it to.
Is this normal or are they meant to be exact?
I think you have a non-spec holder, but someone might correct me. I'd return the holder and get one that's the right size. Otherwise if you need fuses in future, you'll be struggling.
Thanks for the response
I bought a specific item, CIP000100001.
I have been told by the supplier "they can be tricky and you just need to bend them to get them in".
That does not seem correct to me. Engineering and manufacturing tolerances are of the upmost importance.
Can someone tell me if they have experience of these fuse holders, do the fuses just slip on or are you meant to bend them in?
You can see that the fuse will not fit and is sitting on the threads.
Hi @Chamtrev
yes, this is fairly normal with this fuse holder. The trick to get the fuse in is, to bend the holder a bit. You can do that by pressing the 2 bolts towards to each other with some force.
Then, the fuse will go in place without issues.

OK so that clears the issue up, the manufacturing specifications of 50.8mm centre to centre are guestimates, could be 50mm could be 52mm, who knows, just bend things a bit till they fit.
Airbus here I come.;)
I believe that's the Boeing approach on the 787s. ;-)
Hope we have a better answer for you soon.
Little late to the party... by as i search for the M8 on-center specs for Lynx Distributor....
There are two sizes of 70v mega fuses from Litlfuse
One is 51mm (50.8 oc)
Other is 56mm (56.0 oc)
