I will keep an eye out for you, thanks.I haven't played for a few days. I play at various times, since my sleep cycle is not much of a cycle
I've popped on and moved 500 screws from my stash to my inventory. I had 894, so I can spare those 500 (plus whatever I happen to get from scavving as I go along). If we're on at the same time, we can teleport to each other and I'll drop the screws for you.
I think that a useful location for one is the garage/barn between Silvia Homestead and Billing's Homestead. They're SW of Flatwood, across the river, near the river that marks the western edge of the gameworld. Easiest way to find it is to follow the river roughly south from Flatwood until it runs into a river running roughly east-west, cross that river, head roughly west along the far bank until you find a power substation and Hillside Hotdogs. Follow the road roughly south from the hotdog place and you'll soon reach the homesteads. The garage/barn you want is in the fields between the two. One of those half-tube things that were common in the real world during/after WW2. Quonset huts, I think they're called. The only mobs that spawn near there (outside of the Project Beanstalk event that sometimes spawns at one of the homesteads) are some very low-level minor robots (liberators and protectrons) and maybe some very low level scorched. In the barn/garage itself are 3 very low level radroaches. So it's a safe spot to get to and work in.
Thats the one I found and now use, thinking of moving my camp up that way.
