A hardened steel drop-in nozzle for MK8-style hotends, with an M6 thread for 1.75mm filament. MK8 is the classic Creality-style nozzle found on the Ender 3, Ender 5 and CR-10, so this is a direct upgrade that lets those popular machines print abrasive filaments without wearing out. Hardened steel is wear-resistant, standing up to carbon fibre, glow-in-the-dark, wood- and metal-fill filaments that quickly chew through brass, and it handles higher temperatures too. Pick your tip: 0.8mm for balanced faster printing, 1.0mm for high-flow speed, 1.2mm for large-format work, or 1.5mm for extra-wide, maximum-flow printing. Fits straight in, no modifications needed.

Great for
Changing your nozzle
- Heat the hotend
Bring it up to around 200 to 230C so any filament in the nozzle is soft.
- Hold the heater block
Grip the block with a spanner or pliers so it cannot twist, then unscrew the old nozzle.
- Fit the hardened nozzle
Screw the new nozzle in while the hotend is still hot.
- Snug it down
Tighten it firmly while hot so it seals against the heatbreak and does not leak.
Common questions
Will this fit my Ender 3 or CR-10?
Yes. Stock Creality machines like the Ender 3, Ender 5 and CR-10 use MK8 nozzles, so this drops straight in with no V6 upgrade needed. It is the direct way to make one of those printers abrasive-ready.
Why choose hardened steel?
Hardened steel resists the abrasion from composite and filled filaments that would wear out a brass nozzle in hours. It is the right choice for carbon fibre, glow-in-the-dark, wood- and metal-fill materials, and it tolerates higher temperatures too.
Can I print everyday PLA and PETG with it?
Yes, it handles all standard filaments fine. Brass just heats a little faster and costs less, so for purely non-abrasive printing brass can be the better value. Choose hardened when you print abrasives or want one nozzle that does everything.
Which tip size should I choose?
0.8mm gives a balanced, faster print with more flow than a standard tip. 1.0mm opens up the flow for fast, high-throughput printing. 1.2mm suits large-format and structural prints with thick layers. 1.5mm is the widest bore for the fastest, heaviest large-scale prints.
What is an MK8 nozzle?
MK8 is the most common nozzle format on hobby 3D printers, with a standard melt zone and an M6 thread. It is the tip fitted to Creality machines like the Ender 3 and CR-10, plus many clones. It is not interchangeable with an E3D V6 or Volcano nozzle.
