MK8 Hardened Steel Nozzle M6 1.75mm – 0.2–1.0mm Wear-Resistant for Abrasive Filaments 3D Printer

Print with confidence using this MK8 hardened steel nozzle, designed for 1.75mm filament and standard M6 threading. Built for durability, this nozzle is ideal for abrasive filaments such as carbon fibre, glow-in-the-dark, wood-filled, and metal-filled materials.

Compared to standard brass nozzles, hardened steel offers superior wear resistance and a longer lifespan, making it the perfect upgrade for demanding 3D printing applications.

Key Features

• Made from hardened steel for excellent durability
• Designed for abrasive filaments
• Compatible with MK8 hotends (M6 thread)
• Supports 1.75mm filament
• Available sizes: 0.2 / 0.3 / 0.4 / 0.5 / 0.6 / 0.8 / 1.0mm
• Precision-machined for consistent extrusion
• Corrosion and wear-resistant

Why Use Hardened Steel?

Standard brass nozzles wear quickly when printing abrasive materials. This hardened steel MK8 nozzle maintains its diameter over time, ensuring consistent print quality even after extended use with tough filaments.

Nozzle Size Guide

• 0.2mm – Ultra-fine detail printing
• 0.3–0.4mm – Balanced detail and general use
• 0.5–0.6mm – Faster prints and stronger layers
• 0.8–1.0mm – High-flow printing for large parts

Compatibility

• Compatible with MK8 hotend 3D printers
• Suitable for most printers using M6 threaded nozzles
• Commonly used in Ender, CR series, and other MK8-based systems

Note: Compatibility depends on the hotend type (MK8), not just the printer model. Not compatible with V6 or other nozzle formats.

Specifications

Common Applications

• Carbon fibre, glass fibre, and metal-filled filaments
• Glow-in-the-dark and wood-filled materials
• High-wear industrial and functional prints
• Long-term, heavy-use 3D printing

Important Notes

• Requires slightly higher printing temperatures compared to brass nozzles
• Always install while the hotend is heated for proper sealing
• Re-level your print bed after changing the nozzle

Tip: When switching from brass to hardened steel, increase your printing temperature by 5–15°C to maintain consistent extrusion.
