Tanbupu 200Pcs 9 Sizes Nylon Plastic Hole Plugs 1/5" 1/4" 5/16" 3/8" 1/2" 5/8" 3/4" 7/8" 1"Round Hole, Flush Type Panel Knockout Locking Plugs,Screw Covers for Furniture Cabinet Insert End Caps

What this kit is for

I keep a small stash of finishing bits for tidying projects—felt pads, cable clips, and lately, this Tanbupu hole plug kit. It’s a simple idea: snap‑in nylon plugs that fill exposed holes so the surface looks finished again. Think cabinet screw holes after you move a hinge, the unused knockout on an appliance panel, or a rogue pass‑through in a countertop that no longer needs a cable. The plugs sit flush, install by hand, and disappear into the background.

What’s in the kit

The kit is a 200‑piece assortment in nine diameters, all in white with a matte, frosted finish. The spread covers common sizes from 1/5 inch up to 1 inch, with a heavy emphasis on the smaller end. The approximate breakdown in my set matched the listing: more of the 1/5 inch and fewer of the larger 3/4 to 1 inch pieces. That distribution makes sense—small screw holes are common, big panel knockouts are rare.

Each plug has a thin cap with a slight edge chamfer and a flexible set of retaining “teeth” that grip the wall of the hole. The design is the same across sizes, just scaled up. The nylon is RoHS‑compliant, and the molding quality on my kit looked clean: flat caps, no sharp flashing, and consistent edge detail.

Installation: as easy as it should be

The installation process is straightforward:

• Measure the hole. Calipers are ideal; a drill bit shank or a known screw size works in a pinch.
• Pick a plug that’s equal to or up to about 0.5 mm larger than the hole. Slight interference is your friend—it ensures a snug snap.
• Press the plug in by hand. For larger sizes, I sometimes seat the first tooth, then press around the circumference to work the rest in.
• If a plug is stubborn, a touch of soapy water or a quick warm‑up with a hair dryer makes the nylon a bit more compliant.

On painted cabinets and appliances, the plugs seated flush without marring the finish. In unfinished hardwood, breaking the sharp edge of the hole with a light chamfer helps the cap sit perfectly flat. Removal is easy if you plan for it: I align one cap edge with a small notch or seam, then use a plastic spudger to lever it back out. The teeth do their job well; repeated removal will eventually fatigue them, but this is a finishing component, not a serviceable fastener.

Fit and finish

Visually, the matte white blends nicely with most factory‑white appliances and vinyl trim; it’s not glossy, which is good—the plugs don’t catch the eye. In cabinets, the frosted cap reads as “stock” rather than a patch. On wood furniture, the color contrast is obvious, so you’re choosing tidy and reversible over invisible. If you’re trying to color‑match, paintable wood filler or a dowel is still the better route.

Dimensional consistency is solid. The smaller plugs snap in with a satisfying click and resist finger pressure once seated. Larger sizes (3/4 inch and up) require firmer pressure and benefit from a very clean, round hole. On thin sheet metal or plastic panels, the teeth grab decisively; on dense hardwood, the grip depends on the accuracy of the hole diameter.

Real‑world use

I’ve used this kit in a handful of contexts:

• Reversing a mini‑fridge door left four visible screw holes. The 1/4 inch plugs were a perfect friction fit and disappeared against the white enamel.
• A camper countertop had an old cable pass‑through I no longer needed. A 1 inch plug tidied it instantly—no sawdust, no epoxy, just a snap.
• After rearranging shelving in a closet, the exposed bracket holes in a melamine panel took 5/16 inch plugs cleanly, making the panel look new again.
• On a white vinyl fence rail with prior screw holes, the plugs sat flush and stayed put. For outdoor use, I treat these as cosmetic rather than structural; time will tell with UV exposure, but the nylon has held up well so far in a shaded area.

None of those jobs needed tools or adhesive. The result is “designed, not hacked”—which is exactly what these plugs are for.

Where the kit shines

• Convenience and breadth: The nine sizes cover most household and light‑shop needs without a run to the store or a special order.
• Clean, flush finish: The caps sit flat and don’t telegraph a repair from a distance.
• Quick, reversible fix: If you need to reopen a hole later, you can. No sanding, no filler to chip.
• Good material choice: Nylon is forgiving, doesn’t shatter, and grips well across a range of hole wall thicknesses.

Limitations to keep in mind

• Color is fixed: This set is white only. It’s great for appliances, trim, vinyl, and painted surfaces; it’s not the answer for stained wood or black equipment unless you’re okay with contrast.
• Metric holes can be tricky: The assortment is in imperial sizes. For 5 mm or 6 mm factory holes, you may be between sizes. Slight interference is fine; too tight risks deforming a thin panel.
• Not for structural or watertight sealing: These are cosmetic. They’re not gaskets and they won’t hold load. In wet environments, water can still migrate around the cap.
• Thickness matters at extremes: On very thick hardwood (3/4 inch), the teeth have less “spring” room. A precise hole helps. Conversely, on extremely thin sheet metal, use care not to bend the panel while pressing in larger plugs.

Quality notes

Out of 200 pieces, I found a couple with tiny molding nibs on the underside. They still seated flush, but I binned them into the “shop” pile rather than “visible furniture” pile. That’s expected with injection‑molded consumables, and the overall consistency is better than I typically see at this price point.

The cap thickness hits a nice middle ground: thin enough to disappear, thick enough not to flex if someone brushes a hand past it. The retaining teeth are symmetric and don’t leave marks on painted surfaces when installed straight.

Tips for best results

• Measure twice, trial once: If you’re between sizes, start with the smaller plug; if it’s loose, step up one.
• Clean the hole edge: A quick deburr with a countersink or utility blade improves fit and keeps paint from lifting.
• Match sheen: On glossy finishes, a tiny wipe of a non‑greasy plastic conditioner can slightly increase the sheen to match. Test first.
• Keep a size card: I labeled a small card with each plug size and taped one plug to it. It makes future matches quicker.
• For outdoor installs: Use in shaded or sheltered spots if possible. Nylon is tough, but prolonged UV can chalk un‑stabilized plastics over time.

Value

As an assortment, the kit makes sense. Buying individual packs by size is cheaper per piece only if you know exactly what you need and will use dozens of the same diameter. For general shop and home use, I prefer having the spread on hand. The cost per fix is low, and the time savings is real.

The bottom line

I like this Tanbupu hole plug kit because it does a humble job well. The sizes cover the common cases, the material feels right, and the result looks intentional. It won’t replace filler or dowels where you need a stain‑grade repair, and it won’t weatherproof a hole, but for quickly making unused openings disappear—especially on white appliances, cabinetry, vinyl, and painted trim—it’s the right tool in the drawer.

Recommendation: I recommend this kit for homeowners, handypeople, and light‑shop users who want a fast, clean way to cover holes without tools. It’s especially worth it if you handle varied projects and don’t want to chase individual sizes. If you need color matching beyond white or require watertight or structural plugs, look elsewhere; otherwise, this is an easy, effective fix that pays for itself the first time you reach for it.
