Unique-Bargains 0.3mm MK8 Stainless Steel Nozzle 1.75mm 5pcs

Five-Pack 0.3 mm MK8 Nozzles

This set contains five stainless-steel nozzles stamped with their 0.3 mm bore size for quick identification. They are made for MK8 hot-ends that accept 1.75 mm filament and use an M6 thread with a 5 mm thread length. The pack suits owners of compatible printers who want spare or replacement tips on hand.

Consistent Machining and Clean Threads

Each nozzle has a smooth contact surface and a precisely machined orifice so filament flows evenly during printing. The M6 threads are clean and well formed, reducing the risk of cross-threading when you swap tips. Stainless steel resists wear better than brass, so the bore stays accurate through many hours of abrasive or standard filaments.

Direct Brass Replacement for Abrasive Filaments

These nozzles replace the standard brass tips that come on many MK8 extruders, letting you print carbon-fibre, glow-in-the-dark or other filled materials without rapid bore enlargement. The jump is worthwhile when you move beyond plain PLA, ABS or PCL and need a tip that holds its 0.3 mm diameter over long prints. After installation, recalibrate the nozzle-to-bed gap before starting a new job.
