Vertere Titanium cartridge screws are designed and precision machined to provide the best connection between tonearm head-shell and the cartridge where the cartridge body is already threaded to accept M2.5 fixing screws. These add a total of 1.5g mass at the head-shell which could also be advantageous when a lowering of cartridge/tonearm resonance is required. Being made from titanium, these are the perfect match for Vertere reference tonearm.
