McMaster-Carr has socket head in lengths up to 60mm long.
for flathead, Fastenals was a source, but they were special order from Germany and you had to buy lots of 10 screws last time I bought some with shipping they were $60.00 for 10

M6 X 1.0 are easy.

Unless something has changed, and the only change I am aware of is the ebay seller I linked above...Tom

I'm not sure what you're asking.

Cooper screws won't work in an Anschutz, and Anschutz (M6 X 0.75 threaded) screws won't work in a Cooper.

Remington 700 or 40XB screws are the correct diameter and thread for a Cooper 57M...Tom

Ebay 6 x 0.75 screws arrived a few days ago. All the way from China. Threads are correct as is size.
The 50 mm screws are the correct length, The heads needed some work to fit properly. The screw for the front of the triggerguard's head was a bit too wide to fit in the recess, a few minutes in the electric drill and a good file fixed that. The forward screw needing a tapered seat was also done using the electric drill, file and machinists blue to fit the proper taper.
Epoxy bedding to start now.

What is the length of the screws you are trying to buy? .075 is not an easy tread to find .o1mm very common, found 6x.075x25mm (1") flathead socket head screws don't know if this would help.
l had used either flat or rounded head screws to do what you want to do, round head screw I would put a slight bevel under the head to fit the recess. easily done with a file and drill, drill press or lathe.
Screw .075 tread not easily found in all head shapes.

I bought a die (die nut ) and 3 or 4 long 1/4 20 socket head bolts , cut to length , chucked up the bolt in a drill and filed the od down slightly then ran the die on the shank , I have found that in some Anschutz the hole in the aluminum or stock is smaller or to small for the 1/4 bolt , just an option

I thought I had a fix, but was wrong. I picked up some socket head cap screws from a new super-large Ace Hardware today for an Anschutz mount but they turned out to be M6 x .80 rather than .75. Close but not close enough. Since .80 is what my thread gauge shows, and it doesn't appear to be a valid number, maybe my gauge is mis-stamped

.80 pitch is all you will find at Ace. try McMaster-Carr for socket head .80 x 6mm
they have lengths up to 60mm

Flat head you could order them from Fastenals, but I am not sure if they still bring them in from Germany and only in minimum 10 per order

Metric M6 screws have one of two pitches -- 1 or .75. M5 screws have .8 or .5 pitch.
