A snap shackle on a halyard is not likely to fit through a headboard, or in my case where there is a snap shackle spliced on the jib halyard, I flipped it sideways (not used) and put a regular shackle on B/C the snap shackle won’t fit through the roller furler casting. I think snap shackles are mostly intended to be attached to a sail ring.
If you have a snap shackle on the main halyard, you may likely have a regular shackle on your headboard, which of course will work. Just lowers your main a couple inches. Not sure why you take the halyard off every time?

It has a pivoting arm that swings up after inserting through the headboard and secured with a threaded pin. It has worked fine for years and easy to remove and attach, which I do routinely when done sailing for the day. Recently, I twice found it nearly completely unscrewed after a day of rough weather sailing, and that is concerning. I don’t want to lose the halyard up the mast. I am considering replacing it this winter with a standard snap shackle of the sort used on my genoa halyard. I looked at a rigging company web site and they used snap shackles for genoa halyards and pin shackles for main halyards. The logic of that escapes me. On my boat, I take down the roller furling genoa only a few times a season while the main halyard is detached every time I go sailing. I have no idea what the forces are on the main halyard but I would not think much greater than the genoa. Any words of wisdom, or reason not to use a snap shackle for the main?
