Feature: 1. This stainless steel kit is compatible with magnetic surfaces. The universal cartridge mounting kit includes all necessary components to fit any phono cartridge. The included selection of bolts, nuts, and washers accommodates a wide range of cartridge body depths. 2. This mounting kit is made from high-strength stainless steel, not aluminum, as many cartridge manufacturers recommend against using aluminum hardware. For example, the installation instructions for certain cartridges specify avoiding aluminum screws to prevent damage to threaded mounting holes. The weight difference between stainless steel and other materials does not impact performance, as the counterweight at the rear of the tonearm should always be adjusted to achieve the correct Vertical Tracking Force (VTF) recommended for your cartridge and stylus. 3. For optimal performance, ensure the cartridge is properly mounted to the headshell by using the shortest bolts suitable for your cartridge and headshell combination. The hex socket design allows for easy tightening using the included Allen keys. 4. The 6mm, 8mm, 10mm, and 12mm bolts are suitable for most cartridges on the market. The 16mm and 20mm bolts are included for deeper-bodied cartridges. M2 bolts (10mm and 16mm) are provided to fit most Thorens headshells.
