Kitchen cabinet knobs are functional hardware components used for furniture, kitchen cabinet doors, and drawers, playing a crucial role in daily opening, closing, and transmitting force from the user's hand. This product is made from a single piece of SUS304 or SUS316 stainless steel and features a solid cylindrical structure. Compared to traditional stamped or hollow knobs, this model achieves high dimensional accuracy through CNC precision machining.  The surface can be finished with a brushed or polished treatment, maintaining surface uniformity and fingerprint resistance even under frequent use.

1. Stable Material

These kitchen cabinet knobs are made of SUS304 or SUS316 stainless steel, with stable nickel and chromium content.  Their corrosion resistance has been tested to withstand salt spray for over 72–96 hours. Compared to ordinary carbon steel knobs, they are less prone to pitting or oxidation in humid and greasy environments, maintaining consistent structural performance over long-term use.

2. Precise Dimensions

The knob has a top diameter of approximately Φ20mm, a base diameter of approximately Φ13mm, and a total height of approximately 17mm, with a dimensional tolerance controlled within ±0.05mm. This proportion, based on ergonomic testing, reduces the hand torque required for a single opening, improving the operational stability of drawers and cabinet doors during repeated use.

3. Surface Treatment

The knobs are available in brushed and mirror-polished finishes. The brushed texture depth is controlled within the 0.3–0.5μm range, effectively reducing the visibility of fingerprints. The polished version has a surface roughness Ra≤0.8μm, meeting the long-term display requirements for metal finishes in high-end kitchens.

4. Structural Strength

The knob body has a solid structure, and tensile testing shows a single-point load capacity exceeding 80N, making it resistant to deformation under high-frequency pulling. Compared to hollow structures, the anti-loosening performance is significantly improved, and the threaded connection remains stable during long-term use, reducing maintenance frequency.

5. Consistent Processing

Using CNC turning and integrated molding technology, the consistency of height, diameter, and thread depth is ensured for every batch of kitchen cabinet knobs. This avoids visual height inconsistencies during mass assembly, making them suitable for large-scale cabinet projects or customized kitchens with strict uniformity requirements.

1. Home Kitchen Cabinets

These kitchen cabinet knobs can be used on both wall and base cabinet doors in home kitchens, compatible with common door panel thicknesses of 16–22mm. The single-point fixing method simplifies the installation process and maintains a stable feel during frequent daily use.

2. Drawer Systems

When applied to kitchen drawer fronts, the size and force distribution of these knobs have been tested to meet the demands of repeatedly opening fully loaded drawers. The solid structure resists loosening under long-term load conditions, making them suitable for kitchen environments with high storage density.

3. Custom Cabinets

In custom kitchen projects, these kitchen cabinet knobs are easy to match with different door panel materials, including solid wood, plywood, and painted panels. The metal surface treatment allows for a consistent style with the overall hardware system, reducing the risk of design conflicts.

4. Renovation Projects

In kitchen renovation projects, these kitchen cabinet knobs can directly replace existing knobs without modifying the door panel structure. The standardized thread design fits common mounting holes, helping to shorten construction time and control renovation costs.

Q: What thickness of cabinet doors are these kitchen cabinet knobs suitable for?

A: These knobs are designed to fit common kitchen cabinet door thicknesses of 16–22mm, and the screw length has been verified to cover mainstream door panel specifications. For doors of special thicknesses, stable installation can be achieved by replacing the matching screws.

Q: What are the differences between SUS304 and SUS316 for kitchen use?

A: SUS316 contains molybdenum, which gives it superior corrosion resistance compared to SUS304, making it suitable for high-humidity or coastal environments. In typical household kitchen environments, SUS304 is sufficient for long-term stable use.

Q: Are there significant differences in maintenance between brushed and polished surfaces?

A: Brushed surfaces show fingerprints and minor scratches less easily, making them suitable for high-frequency use. Polished surfaces have a brighter visual effect, but require regular cleaning to maintain their luster.

Q: Do the knobs loosen easily after installation?

A: These kitchen cabinet knobs use a solid structure and standard threaded connection. Under correct installation conditions, they can withstand over 10,000 opening cycles and are not prone to loosening during long-term use.

Q: Does this knob support size or surface customization?

A: The knob height, diameter, or surface treatment can be adjusted according to project requirements, meeting different cabinet design schemes while ensuring structural strength. This is especially suitable for bulk customization projects.
