Hello Kristen,
First, let me say that no, I cannot tell you specifically what fasteners I used for the cabin top controls or for any other hardware. The sketches I put together and published simply document what I installed on my boat and, as you have already surmised, does not specify preparation of components or assembly instructions. Since I am only restoring one boat, there is no need to document to that level of detail. The good folks at Ensign Spars (past and present) would be a good source of specific information if you can't figure it out on your own. I believe the only person I asked about fasteners was Chad (formerly of Ensign Spars) about what size rivet to use when re-attaching the Sheer Clamp (3/16 X 1/2 every 6 inches for a total of 124 !!).
What I can offer is, I used best practices for fastening deck equipment as garnered through experience, asking more experienced heads (as you are doing), the many good books written about restoring boats and Google! Best practice here includes; how to prepare the structure you're mounting to, diameter hole to drill and bevel for any given fastener, number and type of washers, type of nut, thread lock, thickness of backing plate, sealant, dissimilar metals treatment, how many threads to leave showing and recommended tightening for the application.
During the planning for my boat's restoration, I built-up a fastener inventory by accounting for all the manufacturer recommended fastener diameter sizes, then determined the most common thread count that accommodated the widest range of lengths for that particular fastener as offered by the supplier and then purchased my best-guess lengths in batches of 10-to-100 depending on use.
As an example, I settled on 10-32's for all my #10's in both Black Oxide and plain finish. I settled on the 18-8 grade whenever I could find it and have a variety of lengths, ranging from 3/4" all the way up to 2-1/2". I think I used 5 different #10 lengths to account for all the different hardware mounted all over the boat. In the case of the Harken 459's, I had to use at least 2 different bolt lengths due to variation in the cabin top thickness on my boat.
Sorry I couldn't offer more help...you'll have to do your own study and revel in the experience!
