1/2 inch will be fine. I think the washer bolt is the same screw from memory, but its several years ago so best check. Certainly UNF. My advice is to run a nice oily taper tap through the captive in the bulkhead before fitted a new screw. Awful to damage the thread and have to replace it.

thought I'd add to this post after my Series One exploits on headlight fitting and in particular seating rims. Be aware that there is a special Series One seating rim. SNGB make it at £25 when the "el cheapo" version commonly available is only £10. That one is fine for later etype models without the closed headlights.
The difference is "el cheapo" puts the h/lamp adjusters at 9&12 o'clock. The £25 version puts them at 3&6 o'clock which is the intended position FOR SERIES ONE cars. Guess what....I purchased "el cheapo" as I didn't know about the £25 version and was advised by the SNGB competitor it was the only seating rim available and to drill extra holes in the headlamp diaphragm at 9&12 to make it work, which I have done...argh!!!!. El Cheapo does do the job, but the 12 o'clock adjuster is tight on the bonnet top/wing joint.....don't make my mistake!!
Still can't understand why the Series One seating rim version should carry such a premium price..what a rip off.
I bought my headlight parts piecemeal and on reflection a kit would have been a better idea....Holden Electrical are a good choice'
