Brass MK8 nozzle set for 1.75 mm filament

This five-piece brass kit supplies 0.2 mm, 0.3 mm, 0.4 mm and 0.5 mm nozzles with M6 threads for MK8 hot-ends. It targets hobbyists and small-shop operators who print PLA, ABS or PCL on 1.75 mm machines such as Creality CR-10 or Prusa i3 variants. The assortment lets users swap orifice size to match layer-height or speed requirements without sourcing separate parts.

M6 thread and 1.75 mm input constrain compatibility

Only hot-ends that accept an M6 thread with a 5 mm thread length and a 2 mm input bore can use these nozzles. Printers built for 3 mm filament or proprietary thread standards will not fit. The brass material handles non-abrasive polymers but wears quickly with carbon-fibre or glow-filled grades, so those filaments are outside the intended use.

Simple hot swap but recalibration is critical

Heat the block to the filament temperature, hold the heater block with a spanner and unscrew the old nozzle with a socket driver. Screw the new nozzle in by hand then tighten lightly while the block is still warm. The supplier notes that the nozzle-to-bed gap must be recalibrated after every change; skipping this step is the most common cause of first-layer adhesion failure.

Questions about this item

Which nozzle diameter should I pick from the 0.2mm, 0.3mm, 0.4mm and 0.5mm options?

The 0.4mm nozzles are the standard choice for general printing; use 0.2mm or 0.3mm for finer detail and 0.5mm for faster, stronger layers.

What does the 1.75mm filament specification mean for my printer setup?

These nozzles accept 1.75mm filament directly through the 2mm input bore, matching the filament size used by most Creality CR-10, Makerbot and Prusa i3 machines.

How does the M6 thread affect installation on my hot end?

The M6 thread with a 5mm length screws straight into standard MK8 heater blocks, so you only need a spanner and socket screwdriver to swap nozzles.
