MK10 hotend structure only allows filament to have little contact with the nozzle. The material of the nozzle must be brass to ensure filament's temperature is the same as the thermistor, so it make the melt plastic more smooth. But the heat conductivity of stainless steel is so poor, it is unscientific and irrational used on MK10 nozzle; Improved Version: an M3 threaded hole has been added to the aluminum block, making it suitable for both M3 and M4 thermistor; Quantity and specification: 1 piece MK10 hotend kit, it include these parts: 0.4mm nozzle with M7 thread 1 piece, throat with 1.75mm PTFE tube 1 piece, aluminum heater block 1 piece. 12 Volt 40 Watt (12v 40w) MK10 3D Printer Ceramic Heater Cartridge with a 1/4-in (6.35mm) Diameter and 1m Wire Specification of nozzle: Compatibility:MK10 hotend M7 thread aluminum heater block; Output diameter:0.4mm; Input diameter:1.75mm; Size:M7; Material:Brass.
