Searching for screws

Ace Hardware if you have one local. McMaster Carr if you have to order. They are super fast processing and shipping. 

Do be aware that allen head fasteners on a Weihrauch will require you to have 3 different sized wrenches on hand to remove the stock, tighten screws, etc. This drives me nuts personally, and I much prefer the factory slotted screws. Nothing worse than being in the woods hunting, or at a FT match and trying to find 3 separate tools just to check that the screws are still snug. 

But most people don't seem to care, so carry on. 
 
I picked up some button head socket caps

 This one was .85. Much nicer to work with. 
I will keep the originals catalogue them, and then lose them. Thanks Crow
