50 Pcs Nozzles Hardened/Stainless/Brass Set for CR-10, Ender 3 + MK8 Cleaning Kit Review (2026)
Updated September 21, 2026 · Research-based review
Our verdict
A large mixed nozzle set that bundles hardened steel, stainless steel, and brass MK8 nozzles in multiple bore sizes with a cleaning kit, aimed at CR-10 and Ender 3 style printers. The variety covers most filament types and years of spares, but sorting so many similar looking nozzles by material takes some care.

What we liked
- + Hardened, stainless and brass in one set cover most filament types
- + 50 Pcs gives spares across materials for years of printing
- + Cleaning kit helps clear minor clogs before replacing a nozzle
Trade-offs
- - Different nozzle metals are easy to mix up once out of the box
- - Generic hardened nozzles may not match premium wear resistance
What is actually in the box
This set bundles MK8 threaded nozzles across several bore sizes, made from three different metals: hardened steel, stainless steel, and brass, plus cleaning tools that typically include tweezers, a wrench, cleaning needles, and a brush. The mix of materials is the main selling point, since each metal suits a different filament category. Brass handles standard PLA, PETG, and ABS well and is the easiest to clean. Stainless steel resists corrosion better and tolerates slightly higher temperatures. Hardened steel is built for abrasive filaments like carbon fiber or glow in the dark blends that would wear a brass bore out of shape over time. Having all three in one set means a printer running mixed materials does not need three separate purchases.
MK8 compatibility
These are standard MK8 threaded nozzles, the same thread pattern used on stock Ender 3, Ender 3 Pro, CR-10, and many similar printers that never had a V6 style hotend installed. That makes this a fit for printers running their original hotend rather than ones already upgraded to a V6 or V6 clone hotend, which use a different thread pattern entirely. Buyers should check their printer's stock hotend type before ordering, since an MK8 nozzle will not thread into a V6 style heater block, and the two designs are not interchangeable despite superficial similarity.
Sorting and using a mixed metal set
With dozens of nozzles across several sizes and three metals, keeping track of what is what after opening the box takes some organization, since hardened steel and stainless steel nozzles can look similar to the eye once removed from packaging. A simple approach is to sort by size and metal into a labeled tray or small parts box immediately after unboxing, rather than trying to identify nozzles later by appearance alone. The bundled cleaning tools are useful for routine maintenance regardless of nozzle material, letting a partially clogged nozzle get cleared with the needles before reaching for a full swap.
Where quality expectations should sit
A set at this scale is priced for volume and spares, not for chasing the tightest possible tolerances of a boutique single nozzle. The brass and stainless nozzles are generally reliable for everyday printing, while the hardened steel nozzles in a bundled set like this may not match the wear resistance of a premium branded hardened nozzle sold on its own, since hardening processes and steel quality can vary between budget bundles and specialist brands. For someone printing abrasive filament occasionally, that is a reasonable tradeoff. For heavy, daily abrasive filament use, a dedicated premium hardened nozzle may hold its bore size longer.
Who this set fits
This kit suits owners of MK8 hotend printers who want a broad range of nozzle sizes and materials on hand without shopping around for each one separately, along with basic cleaning tools included at no extra cost. It is a good match for anyone who experiments with different filament types, since having brass, stainless, and hardened steel on hand means the right nozzle is already available rather than back ordered. It is a weaker match for V6 hotend owners, since the thread will not fit, and for anyone who wants the absolute best wear resistance from their hardened nozzles specifically, where a dedicated single brand option may perform better.
Frequently asked questions
Will these nozzles fit a V6 style hotend?
No. These are MK8 threaded nozzles, which fit stock Ender 3, Ender 3 Pro, and CR-10 style hotends, not V6 or V6 clone hotends that use a different thread pattern.
How do I tell the hardened steel nozzles apart from the stainless ones?
They can look similar once unpackaged, so sorting them by size and metal into a labeled tray right after opening the box is the easiest way to avoid mixing them up later.
Are the hardened steel nozzles in this set as good as premium hardened nozzles?
They should handle occasional abrasive filament fine, but budget bundled hardened nozzles may not match the wear resistance of a dedicated premium hardened nozzle used heavily with abrasive materials.
Does the set include cleaning tools?
Yes, sets like this typically bundle tweezers, a wrench, cleaning needles, and a brush alongside the nozzles for routine maintenance and clearing minor clogs.
