When working with a creality cr 20, maintaining a flat print surface across repeated print jobs is often the most tedious hurdle hobbyists encounter. The standard plastic adjustment dials and loose factory coil springs frequently loosen during the high-speed vibrations of the Y-axis carriage, leading to detached base layers and uneven first-layer squish. Installing the Creality Metal Leveling Nuts upgrade kit offers a straightforward physical fix designed to combat bed drift by swapping weak stock parts for rigid machined aluminum dials and heavy-duty die springs.

In this review, we examine whether this hardware bundle permanently solves recurring creality cr 20 bed leveling drift. We cover the thirteen included components, inspect the mechanical tolerances, explore the installation process, and evaluate how the stiffer spring tension holds your calibration steady over extended print sessions. We also explore the utility of the included brass extruders, weigh this mechanical upgrade against modern automated platforms, and answer critical setup questions so you know exactly what to expect before picking up your tools.

What You Get With the Creality Metal Leveling Nuts

Tackling Print Bed Drift on the Creality CR 20

Bed drift occurs when standard mechanical fasteners back out under repetitive motion. The print surface of the CR 20 moves back and forth along its aluminum extrusion on eccentric rollers, subjecting the build plate to constant micro-vibrations and thermal changes. When stock components are loose, these vibrations gradually twist factory adjustment wheels, throwing off clearance between the bed surface and the hotend tip. Upgrading to creality yellow die springs significantly increases upward force against the mounting bed carriage, creating friction that keeps the hardware firmly locked in place.

The engineering difference between standard wire coils and yellow flat-wire die springs lies in compression resistance. Yellow die springs feature a rectangular wire cross-section that resists lateral shifting while supplying much higher tension across its 20mm length than standard circular wire springs. By applying higher static pressure between the heated aluminum bed plate and the lower carriage bracket, the springs eliminate subtle wobbling. This tension ensures that once you find the sweet spot during calibration, the mechanical alignment remains stable over dozens of printing hours.

When you pair that spring stiffness with red aluminum thumbscrews, adjusting the platform becomes considerably more consistent. Factory plastic wheels flex under finger pressure, often making small rotational corrections imprecise and difficult to gauge. The 60mm aluminum wheels provide a solid, unyielding surface that translates every slight turn directly into vertical movement. For users managing remote setups with accessories like the creality wifi box, eliminating manual bed drift means fewer aborted prints and less need to physically intervene between scheduled jobs.

Installation Process and Hardware Fit

Executing a creality cr 20 spring replacement is an accessible project, but it requires patience and orderly disassembly. You begin by fully loosening each existing adjustment wheel until the fasteners release from the four corner carriage bolts. Once the heated platform is lifted clear of the lower carriage, the stock springs slip off the studs. The listing indicates that users simply take off the old components and put on the new nuts and springs, making the mechanical swap an unchallenging direct replacement for the stock parts.

When sliding the 8mm by 20mm yellow springs onto the corner carriage bolts, you immediately notice the firmer spring rate. Because these springs compress with greater resistance, compressing all four corners down evenly takes steady, two-handed pressure during the initial thread engagement. The 60mm wide-diameter creality cr 20 bed leveling nuts make catching the threads much easier on the fingers. Their knurled outer perimeter provides ample hand grip, allowing you to wind each corner downward until the springs sit roughly fifty percent compressed.

After mounting all four corners, the final step involves setting your physical Z-axis endstop and working through a standard four-corner tramming routine. Because the yellow die springs are slightly stiffer than factory coils at rest, your initial bed height might sit a millimeter higher than before. Verifying that the nozzle does not dig into your print surface when homing the printer is essential before executing your first test print. Once the initial tramming is complete, the increased tension ensures the screws hold their positions through aggressive acceleration and high-speed infill moves.

Extruder Maintenance and Included Nozzles

Alongside the bed hardware, this thirteen-piece accessory bundle includes five standard 0.4mm brass nozzles. Over weeks of running abrasive or filled filaments, brass nozzles suffer bore enlargement and tip wear, degrading print precision, stringing resistance, and layer consistency. Bundling fresh extrusion tips directly with bed hardware gives owners an immediate way to handle a routine creality cr 20 nozzle replacement without hunting down separate parts from different vendors.

The included nozzles feature the standard 0.4mm orifice diameter that balances print speed with fine detail across typical layer heights between 0.12mm and 0.28mm. Because the listing does not specify thread pitch or heat break compatibility beyond the broad machine compatibility list, these nozzles follow the standard MK8 style geometry typical of Creality hotends. When performing nozzle swaps, always remember to heat the hotend block up to working temperature before final tightening to prevent plastic leakage around the heat break threads.

Having multiple replacement nozzles on hand ensures you can quickly refresh your extrusion path whenever you experience a stubborn filament clog or notice uneven line widths. While high-performance printers like the creality k2 pro incorporate sophisticated hardened steel quick-swap assemblies, classic machines rely on these standard threaded brass units. Keeping five fresh spares in your workshop drawer makes keeping the machine running smoothly both simple and predictable.

Evaluating Bed Rigidity and Hardware Value

Looking closely at the underlying creality cr 20 specs, the printer relies on a traditional cantilevered bed assembly that moves across the Y-axis. This moving-bed design makes rigid physical retention hardware far more critical than on CoreXY platforms where the build plate only drops vertically along the Z-axis. Factory plastic wheels can warp over time due to radiant heat radiating from the underside of the bed heater, which gradually reduces tension on the adjustment bolts.

The machined aluminum construction of these red dials eliminates heat-related warping entirely. Aluminum handles high temperatures without losing rigidity or warping around the central threaded brass insert. Furthermore, the knurled rim delivers reliable finger traction, letting you make adjustments of a quarter-turn or less with precision. When undertaking broader creality cr 20 upgrades, replacing the bed leveling running gear is widely considered the foundational first step toward establishing baseline reliability.

Although automated leveling sensors can compensate for a slightly tilted bed digitally, they work best when the physical bed is already mechanically trammed as flat as possible. Letting software constantly compensate for massive tilt angles can introduce subtle dimensional distortions along the vertical axis of your finished parts. Investing in stable mechanical retention means any auto-leveling routine has less tilt to correct, resulting in cleaner vertical walls, reliable first layers, and square corners on functional prints.

Is the Creality Metal Leveling Nuts Worth It

If you are frustrated by having to re-tram your machine before every long print, this simple hardware set provides outstanding practical value. Asking whether the creality cr 20 leveling kit worth it comes down to how much you value your setup time. For everyday makers who simply want to send a file to the printer and walk away with confidence that the first layer will stick, the extra holding tension of the die springs and the durable build of the aluminum thumbscrews solve an annoying operational pain point.

Beginners and intermediate hobbyists will appreciate how easily this kit installs without requiring permanent frame modifications, soldering, or firmware changes. You do not need to recompile Marlin or configure custom sensor offsets to reap the benefits of this upgrade. In under twenty minutes of basic hand-tool assembly, you can strip away the weakest links in the bed mounting assembly and install components built to withstand heavy daily printing.

However, if you are seeking a push-button, hands-off calibration system, understand that this hardware kit does not turn a manual machine into a fully automated CoreXY platform. You must still execute the initial four-corner leveling process manually using a piece of paper or a feeler gauge. For those operating a busy workshop alongside other tools such as the creality falcon 2 40w, spending a few minutes to install these physical parts eliminates regular print failures and keeps your printer running without constant supervision.
