A new, unused set of high-quality stainless steel cartridge mounting screws, nuts, and resin washers that minimally affect sound quality. Plastic washers are also included to prevent scratches on the cartridge and shell. Of course, these are standard flat-head screws with a minus head for cartridges. The 5mm screws often don't require nuts, so we've omitted them to reduce the price. Made of stainless steel, these are recommended for those who are more particular about sound quality than with aluminum screws. 2.5x5mm 2.5x8mm 2.5x12mm 2.5x16mm 2.5x20mm Two of each size listed above. Stainless steel nuts x8 Washers x10 A total of 28 pieces in this set. #MC Cartridge MC Cartridge #Step-up Transformer Step-up Transformer #Turntable Turntable #Analog Record Analog Record #Cartridge Record #Tonearm Cartridge #Record Phono Equalizer #Phono Equalizer Tonearm #Audio Audio Bolt Screw #Head Shell #Lead Wire #Screw #Nut #Washer #Bolt #Screw
