  • Stainless steel resists wear from abrasive filaments

0.3 mm MK8 Stainless Steel Nozzle Pack

This two-piece set provides 0.3 mm diameter nozzles built from stainless steel for MK8-style hot ends that accept 1.75 mm filament. The M6 thread with a 5 mm length matches the standard MK8 pattern, making the parts suitable for owners of compatible 3D printers who need a harder-wearing tip for abrasive filaments.

Simple Threaded Swap With Hot-Tightening Step

Installation requires heating the hot end to the printing temperature, then unscrewing the old nozzle while holding the heater block with a spanner and fitting the new one using a socket driver. The supplier notes that the threads are clean and well formed, but warns that the nozzle and block remain extremely hot during the change, so contact must be avoided to prevent burns.

Hardened Tip For Abrasives At Standard MK8

Stainless steel resists wear from filled materials such as carbon-fibre or glow-in-the-dark filaments that would quickly erode a brass tip. The 0.3 mm orifice limits maximum layer height and flow rate compared with larger nozzles, and the fixed 13 mm overall length and M6 thread mean the part only fits hot ends designed to the MK8 specification.
