Gunsmithing 8-40 screw length

[jesseanderson2]

I just ordered a seekins 20 MOA base on my 700p lapua for a nightforce. I don't know what length of 8-40 screws to buy. I find them in lengths of .360", .205",.280". I don't mind cutting/sanding them down a little however if I could get the right size first or close that would really help. Thanks for your time

Jesse,

I measured some that came with a MKIV base I have for a M-700 LA.
They measure .323 OAL and .220 thread length on the short ones and .453 OAL and .350 thread length on the long ones.

Hope this helps.
