What's the recommended hardware for mounting things like ANL current limiters, fuse blocks etc?

Do you mean AN or not Bob? Or just what type of fastener, like AN3-? ? I'll be doing this same thing shortly as well, and I haven't given any thought to it. For the ANL, I'll probably use AN bolts in to a plate nut. Fuse blocks will get AN bolts with nuts on the threads.

Does that help, or am I not even close?

I guess I man the whole shootin' match. I bought fuse block holders and the current limiter base from B&C. It appears to want a flush head of some sort. And on the base, on the firewall side, it looks like it has an inset for something -- a washer? No idea.

Bob-

For the ANL current limiter I used a #10 MS24694 countersunk screw. I don't have the length, but if you want, I will unscrew it and take a look for ya (I do have a 063 backing plate and a platenut, FYI).

For the fuse blocks, they can take a #10 screw. However, I couldn't find a #10 screw or bolt who's head would be recessed in the hole in the fuse block nicely. So I used #8 AN515 screws with AN960-8 washers and the appropriate lock nut. Once again, if you want me to get the size screw I used (I used two lengths - one for holding one fuse block to the rib, and another for holding two fuse blocks to the rib), let me know. The #8's seemed to work fine. After all, its not like the fuse block mounting is structural. Its plastic!

Thanks Mike. No need to get the lengths. I'll fit an AN-3 bolt in there until I figure out the right size and then order that size in a #10.

Many thanks!

Bob

I used either #6 or #8 AN screws to mount my whole instrument panel. I used plate luts in some places and other I used AN lock nuts of the correct size. The RV-A plans call for the use of #10 screws and plate nuts to screw the boot cowl to the aluminum angle on the Instrument panel. The other screws are #8. My circut breaker switches all used #8 Screws. The Dynon use #6 screws and nutplates.
