Screws and Nuts Screws and nuts are made of brass with excellent rigidity, and 24K gold plating is applied to enhance corrosion resistance while creating a luxurious feel around the cartridge. In addition, the gold-plated layer, which has a different hardness from that of brass, disperses material-specific vibration modes. Flat-head flat head screws are used for the screws, which are easier to tighten than Phillips-head screws because the screw heads are less likely to be crushed. The flat knurling on the nut prevents slippage, making it easier to press down on the nut when tightening and preventing the screw from spinning out. The outer diameter of the screw head/nut is a small 4mm to prevent damage around the cartridge, and can also be used with headshells that have a counterbore for screw head fitting.
