What to attach compass with

I've called bolt depot to ask what they recommend to use to attach a compass with, stainless, brass or silicone bronze. I think there recommendation was bronze. The phone was poor connection. I thought I would come to the place of all knowledge to ask. I have a Ritchie navigator compass with a wood faring block that will be installed. The wood block is about 2.25 inches at its thickest and about .25 inches at its thinnest. I was thinking of using a machine screw to fasten both the block and compass together to the bulkhead. Have access to back of bulkhead of course to attach nut.

Any advice is appreciated,thanks. Adam z.

I think my compass is in with stainless screws.
Test your screws with a magnet - if they stick to the magnet, get different screws.

As Al suggests, different grades of stainless have different magnetic properties and fasteners are notoriously low grade. Silicon bronze fasteners are a good combination of non-magnetism and strength. If you can't find what you're looking for in silicon bronze, go with brass. Everything inside your compass is brass and the adjustment screwdriver that came with the compass originally was also brass.

I think my Ritchie (I replaced it a few years ago) came with nylon screws.

I would think that anything non magnetic would work just fine.
