  • Five nozzle sizes cover fine detail to fast drafts

  • M6 × 5 mm thread fits MK8 hot-ends directly
  • Stamped diameter on each nozzle speeds identification
  • Clean threads and consistent bore reduce clog risk

Five-diameter MK8 nozzle kit

This set supplies five stainless-steel nozzles for MK8 hot-ends that accept 1.75 mm filament. The diameters cover .2, .3, .4, .5, .6, .8 and 1 mm, letting one printer switch between fine detail and high-flow jobs. Each nozzle is stamped with its size for quick identification. The M6 thread and 5 mm thread length match the standard MK8 heat-block interface.

Stainless steel resists abrasion

Stainless steel withstands filled filaments such as carbon-fibre or glow composites that wear brass quickly. The smooth contact surface seats cleanly against the heat break, reducing leak paths. Clean M6 threads engage without cross-threading, so swaps take minutes with a spanner and socket driver. Overall length is 13 mm and outer diameter is 6 mm, fitting the stock heater block envelope.

Size-stamped nozzles speed workflow

Every nozzle carries its diameter on the flank, eliminating guesswork when reaching for the next print. The pack includes .2, .4, .6, .8 and 1 mm tips, covering the most common layer-height choices. After installation the supplier advises reheating to 180-220 for PLA or 240-280 for ABS, then recalibrating the nozzle-to-bed gap before printing.

Questions about this item

What M6 thread length does the MK8 nozzle set use, and how does it limit compatible hot-ends?

The nozzles have a 5 mm M6 thread, so they only fit hot-ends with an M6 × 5 mm threaded heater block.

What overall length and diameter must the printer's heater block accommodate for these nozzles?

Each nozzle measures 13 mm long by 6 mm in diameter, requiring a heater block with a matching bore and clearance.

What temperature should the hot-end reach before unscrewing the old nozzle, and why is reheating critical?

Heat to 180–220 °C for PLA or 240–280 °C for ABS, then keep the block hot while turning the nozzle to avoid seizing.
