JOY DECOR 18 Pack Matte Black Cabinet Drawer Hardware 30mm Kitchen Cabinet Knobs Drawer Pulls with Installation Screws for Dressers Kitchens Cupboard

Why I tried this knob set

A small hardware swap can make a surprising difference, so I tested a pack of JOY DECOR’s matte black knobs across a few pieces: a painted dresser, a pair of bathroom vanity doors, and a handful of kitchen drawers. I wanted something simple, modern, and consistent enough to tie spaces together without calling too much attention to itself. This 18-pack looked like a practical choice for a budget-friendly refresh.

Design and build quality

These are compact round knobs—30 mm (about 1.18 in) in diameter and 22 mm (7/8 in) tall—with a subtly concave face that improves grip. The matte black finish leans satin rather than chalky; it diffuses light nicely and resists fingerprints better than gloss. On a white vanity, the contrast is clean and understated; on a dark-stained dresser, they disappear in a good way.

Construction is lightweight metal with a hollow body. They don’t have the dense heft of solid brass or steel hardware, and if you tap one off the door, you’ll hear that familiar hollow ring. That said, the edges are clean, the seam lines are tidy, and the finish was consistent across my pack—no color shifts or texture mismatches between knobs. The underside base sits flat on the surface and didn’t rock or leave high points that could mar paint when tightened by hand.

The concave center is the nicest touch. It gives your fingers a natural place to land, which makes small pulls feel a bit more secure, especially on narrower doors where you typically pinch from the side.

In the box and compatibility

You get 18 knobs and two screw lengths per knob: an M4 x 20 mm and an M4 x 45 mm machine screw. Note: in my set, the long screws were tucked under the cardboard at the bottom of the box—easy to miss if you don’t check.

Screw length is the make-or-break detail with knobs. Here’s how these sizes shook out for me:
- 20 mm worked on thinner drawer fronts (around 1/2 in or 12–13 mm) and on a dresser with shallow pre-drilled holes.
- 45 mm was too long for most cabinet doors and drawers unless I used washers or cut the screw down.

For standard 3/4 in (19 mm) cabinet doors and drawer fronts, an M4 x 25–30 mm screw is often the sweet spot, which isn’t included here. I had a small box of spare M4s on hand; once I swapped in 25 mm screws for the kitchen drawers, installation went smoothly. If you don’t have extras, plan to pick up a handful so you’re not relying on washers to take up slack.

Installation experience

Knob installs are straightforward, but a few small choices make the difference between a tidy half-hour and an afternoon of fiddling:
- Pre-check your hole diameter. These use M4 machine screws, which like a 4–5 mm through-hole. Existing 3/16 in cabinet holes were perfect.
- Hand-tighten. Because the bodies are hollow and lightweight, I wouldn’t use a drill/driver to snug them down. A screwdriver gives you better feel and prevents stripping.
- Align consistently. A simple cardboard or plastic template keeps your placement consistent and makes a big visual difference, especially when you’re installing 18 at once.
- Protect the finish while tightening. I used a piece of painter’s tape under the screwdriver head to avoid scuffs on the face during the last quarter-turn.

On the bathroom vanity and dresser, installation was quick. On thicker kitchen fronts, I needed different screw lengths to get the bite right. Once installed, the knobs sat flush, didn’t spin, and didn’t telegraph any wobble.

Day-to-day use

Ergonomically, the concave top is what elevates these from “generic round knob.” You can hook a finger and pull without slipping, which is helpful on heavier drawers. Still, 30 mm is on the smaller side, and I notice that on deep, high-friction kitchen drawers loaded with cookware. They work, but they don’t offer the leverage of a larger 34–38 mm knob or a bar pull. For bigger, heavier drawers, I’d either use two knobs or choose a pull.

The finish holds up well against casual contact—no early chips or edge wear on my set after several weeks. In a humid bathroom, I didn’t see any discoloration or spotting, and routine cleaning with a damp cloth kept them looking uniform. Avoid abrasive cleaners or scouring pads; matte finishes can burnish to a shine if you scrub too aggressively.

Durability notes

These are designed for economy and volume, not heirloom weight. A few practical considerations:
- Don’t over-torque. You don’t need to crush the base into the wood to get a solid install. Hand-tight and a tiny dab of blue threadlocker if you’re worried about loosening over time is sufficient.
- If your cabinet paint is soft, consider a thin felt washer behind the base to prevent a witness ring as the knob beds in.
- If you have high-traffic, high-impact environments (busy rental kitchens, mudrooms where bags get snagged), a heavier, solid knob will feel more reassuring.

Within their intended scope—dressers, nightstands, bathroom and light-duty kitchen use—these performed without drama.

Aesthetics and cohesion

Uniformity is the quiet win. With 18 matching pieces across a room or two, you get a cohesive look that reads “intentional” rather than “mixed spare parts.” The matte black pairs well with nickel hinges and stainless appliances; mixing metals is fine when finishes are balanced. On shaker cabinets, these land squarely in modern-traditional territory; on flat fronts, they look pleasantly minimal.

Value

For the cost-per-piece, this set punches above its weight. You’re paying for consistency, finish quality, and volume, not premium mass. If you’re updating a rental, prepping to sell, or refreshing a room on a budget, the impact-to-cost ratio is excellent. If you want the tactile satisfaction of a solid, weighty knob, you’ll need to spend more and likely buy smaller packs.

Who they’re for

• Great for: Budget-conscious refreshes, staging, rentals, secondary spaces (laundry, guest bath), dressers and nightstands, smaller kitchen drawers.
• Maybe not for: Oversized or heavy drawers, owners seeking high-end heft or larger-diameter pulls, installs where exact screw length is critical and you don’t want to source extra M4 sizes.

Tips before you buy

• Measure your drawer/door thickness and count on picking up M4 x 25 mm or 30 mm screws for standard 3/4 in fronts. The included 20 mm and 45 mm may not cover every scenario.
• Order a simple drilling template if you’re starting fresh holes, or use a scrap jig to keep alignment perfect.
• If you’re on the fence about size, mock up a 30 mm circle with tape on a door front to visualize scale.

Pros and cons

Pros:
- Clean, uniform matte black finish
- Concave face improves grip despite compact size
- Large, consistent 18-pack for cohesive projects
- Simple, smooth edges that sit flush and protect finishes
- Excellent value for multi-room refreshes

Cons:
- Small 30 mm diameter feels modest on large or heavy drawers
- Hollow, lightweight construction lacks premium heft
- Included screws (20 mm and 45 mm) miss the common 25–30 mm middle ground
- Requires hand tightening; not ideal for aggressive installs

The bottom line

I like this set for what it is: a clean, modern, budget-friendly way to update multiple pieces at once. The finish is consistent, the grip is better than most plain rounds, and the look integrates easily with a wide range of styles. You do trade away heft, and you may need to source a couple of intermediate screw lengths for a perfect fit on standard cabinetry.

Recommendation: I recommend these knobs for cost-effective refreshes, rentals, and secondary spaces where you want a cohesive, contemporary look without overspending. If you prioritize premium weight or you’re outfitting heavy drawers you open dozens of times a day, consider a larger or solid-metal alternative. For most light-to-medium duty applications, though, this set gets the job done cleanly and affordably.
