Big cartridge screws?

Great question Doug - unless you are constantly adjusting things like VTF, it is one and done.

What's VTF got to do with adjusting cartridge screws ?

It really depends on what cartridge your mounting and if your trying to add extra mass with the soundsmith's. I needed a few extra grams to get my resonate freq right so I used their brass screws and they did the trick.

Also since my cartridge also needed a nut on the bottom side, aka they dont screw right into the cart, those screws prevent you from having to have fumble around with a little screw driver while balancing the nut, which is nice.

@sunnyboy, when you increase VTF for example, the stylus may ride lower due to added weight causing the overhang to increase in length requiring a cartridge in the headshell adjustment.

Absolutely correct, every time you change one parameter it effects everything else. I set VTF after all other adjustments are made ie the cart is aligned with a MintLP. I only adjust the cart screws to get the overhang and align the cantilever with the protractor and then tighten the cart screws and I am done. Last of all set the VTF. If you using shims in the head shell to adjust VTA the cart screws might come into play, OTW, adjusting cart screws has IMO little to do with VTF or even VTA.
YMMV
