50 pcs. M2.5 Universal 24TDOOTD Phono Head Mounting KitFeature:1, These stainless steel kits can be sucked by magnet. This universal cartridge mounting kit includes everything needed to fit each phono cartridge. This selection of bolts, nuts and washers cater to the full range of cartridge body depths.2, please note that this mounting kit is made of high-strength stainless steel and not aluminum, as many cartridge manufacturers specifically advise against the use of aluminum. For example, the Ortofon 2M cartridge assembly instructions clearly state "never tighten screws and never use aluminum screws as they may get stuck in the threaded holes of the mounting plate". The weight of the stainless steel screws compared to aluminum or other materials is also negligible, as you should always adjust the counterweight on the back of the tonearm to ensure that you have set the correct vertical tracking force (VTF) recommended for the cartridge and stylus.3 To get the best performance from your hardware, it is imperative to ensure that the cartridge is properly mounted to the headshell by making sure that always use the shortest screws that will accommodate the cartridge/headshell combination. The socket head on the screws allows for easy tightening with the Allen wrenches supplied.4, 6, 8, 10 and 12mm screws are ideal for mounting most cartridges on the market. 16 and 20mm screws are included for the deeper cartridges, and M2 screws (10mm and 16mm) are included with most Thorens headshells.Specification:Color: SilverMaterial: Stainless Steel Size: As the picture shownQuantity: 1pcNote:Due to the difference between different monitors, the picture may not reflect the actual color of the item.
