Anyone tried these screws?

[Dom in Dorset]

I bought some cheap machine heads for a bass I'm building , they seem fine but the screws that came with them break if you look at them (one broke because I though about them. There goes another. Damn.)
I'm thinking of getting some of these , anyone tried them , any good?

Haven't tried those screws but have been very happy with all the bits I bought off Black Dog, can't see them being bad from them.
