Questions about this item

How do I install the M2.5 screw, nut and washer without cross-threading the cartridge?

Start each M2.5 screw by hand through the headshell slot, add the matching washer and nut, then tighten gently with a small hex driver until the .30, .41, .45, .53 or .65 in bolt seats flush — do not force the threads.

What part of this kit will wear out first and need replacing?

The aluminium washers can deform after repeated cartridge swaps; keep a spare set of the five lengths so you can refresh the vibration-damping surface when the washers no longer sit flat.

Which dimension limits how many times I can swap cartridges before the hardware binds?

The 2.5 mm thread pitch on every bolt means the aluminium threads will gall before the 7.5, 10.5, 11.5, 13.5 or 16.5 mm shank lengths become an issue.
