Xujinsongg Cam Lock Nuts and Cam Screws, 110 Pcs Cam Locks for Furniture Connecting Cam Lock Fittings, 3 in 1 Cam Connector Bolt Fittings Fasteners Hardware Parts for Drawer Dresser Cabinet

Why I keep this kit in my toolbox

Flat-pack day used to mean a hunt through junk drawers for a spare cam lock or two. After one too many builds stalled by a stripped cam or a missing connector, I started keeping a dedicated cam fastener kit on hand. The Xujinsongg cam lock kit has become the one I reach for. It’s a straightforward, no-frills assortment of cam nuts, cam screws, and plastic expansion anchors that covers the majority of the “I’m one piece short” and “this cam just exploded” scenarios that come with ready-to-assemble furniture.

What you get

The kit includes 110 pieces in a segmented plastic organizer:

• 10 cam nuts (11.5 x 10.5 mm)
• 15 cam nuts (11.5 x 12 mm)
• 10 cam nuts (15 x 11 mm)
• 15 cam nuts (15 x 13 mm)
• 30 cam screws
• 30 plastic expansion nuts (anchors)

The sizes address two common cam diameters (approximately 11.5 mm and 15 mm) in two heights each, which covers a wide swath of desks, dressers, cabinets, and bookcases. The 30 cam screws are the standard machine-threaded style that mate with those nuts, and the plastic expansion anchors are handy when a pre-drilled hole starts to wallow out and won’t hold a screw securely.

Build quality and design

Most cam hardware shipped with budget furniture is pot metal with soft screws that chew up under modest torque. The screws in this kit are alloy steel with crisp threads; they seat easily and resist rounding under a driver. The cams themselves feel dense and machine-cleaned with well-defined slots, and the fine thread engagement is noticeably smoother than the crumbly, gritty feel I often get from bundled hardware.

I also appreciate the “no drama” cams: they lock with a firm, positive quarter-turn without the skipping or sudden give that invites over-tightening. That’s partly down to the thread finish and partly to the tight fit of the cross-slot. It sounds minor, but a clean, consistent cam action speeds a build and reduces the chances of crushing particleboard around a poorly fitted connector.

The plastic expansion nuts are generic, but effective. They’re not miracle workers, yet they give stripped holes a second life and hold better than trying to reuse an over-loosened screw in raw chipboard.

In use: repairs and assembly

I’ve used this kit for three jobs so far:

• Replacing two disintegrated cams during the assembly of a budget bookcase. The original cams cracked at the slot; the 15 x 13 mm replacements from this kit dropped in and locked cleanly. No drama, and the shelf is still tight weeks later.
• Completing a dresser build that arrived one cam short. The 11.5 x 12 mm cam from the kit matched the pre-drilled housing perfectly and the supplied screw mated without binding.
• Tightening a wobbly cabinet where a panel screw kept spinning. I drilled the hole slightly, pressed in one of the expansion anchors, and re-drove a screw. It snugged up nicely and held after a dozen door cycles.

Across those uses, I didn’t run into any quality red flags. Threads were consistent, the driver slots didn’t deform, and the screws didn’t mushroom with normal torque. The cams also sat flush in their pockets, which helped keep panels aligned during assembly.

Fit and compatibility

Cam hardware looks universal, but there’s more variation than most people expect. The kit’s four cam nut sizes cover a lot of common patterns, especially in flat-pack cabinets, dressers, and shelving. Two notes from my experience:

• The diameter matters more than the height for initial fit. If a cam spins freely in the pocket, you’re in the wrong diameter (usually 11.5 vs. 15 mm). Height differences (11 vs. 13 mm) change how far the screw tip engages and can affect clamping force, but a 1–2 mm difference will often still work in a pinch.
• The cam screws included are a sensible “middle” length for most panels. They worked in every case I tried. If you’re dealing with unusually thick tops or very thin side panels, you may still need different screw lengths.

One limitation is labeling. The compartments aren’t individually marked by size. Out of the box, I measured and labeled each section with a fine marker so I wouldn’t be second-guessing mid-build. Not required, but it saves time.

Tips for best results

A few practices have made this kit even more useful:

• Test-fit with calipers or a quick ruler check. Matching cam diameter to the pre-drilled pocket prevents chatter and loosening.
• Don’t over-torque. Cams are for clamping, not crushing. Turn until snug and stop; the fine threads in this kit make it easier to feel that point.
• Keep the screw perpendicular. If the pilot angle is off, the cam will fight you and feel like it’s not engaging. Back out, realign, and try again.
• If a hole is sloppy, use the expansion anchor. Drill a clean hole, tap in the anchor, and re-drive the screw; it spreads the load in chipboard.
• Mark your organizer. Labeling by size avoids guesswork, especially if you’re helping someone else mid-assembly.

Where it falls short

No kit will cover every furniture brand or every quirky fastener spec. A few nitpicks:

• Size coverage is broad but not exhaustive. I ran into one oddball cam pocket that was between the supplied sizes. I finished the job with a different connector style. That’s an edge case, but worth noting.
• No length options for cam screws. The included screws are the common size, and they worked in my projects, but it would be nice to have short and long variants in the same organizer.
• Labeling could be better. Clear size markings on each compartment would make the kit friendlier to novices.
• No instructions. If you’ve never used cam fasteners, there’s no quick-start card. A simple diagram showing cam orientation and screw alignment would prevent most beginner mistakes.

None of these are deal-breakers, but they set expectations. This is a practical assortment, not a master set that guarantees a match for every piece of furniture on the market.

Who it’s for

• DIYers who assemble a few pieces of flat-pack furniture a year and want insurance against missing or fragile hardware.
• Landlords or facilities folks who regularly tighten up dressers and cabinets between tenants.
• Anyone repairing budget furniture where a single failed cam can otherwise sideline a build.

If you’re a pro cabinetmaker working on custom joinery, you’re unlikely to touch cam fasteners. For the rest of us dealing with particleboard, veneered MDF, and mass-market kits, this is exactly the kind of box that saves an afternoon.

The bottom line

The Xujinsongg cam lock kit does the simple things well: decent alloy-steel screws, clean cam nuts that lock without drama, and enough sizes to solve most missing or broken fastener headaches. The plastic expansion anchors extend the life of tired panels, and the organizer keeps everything ready for the next repair.

I’d like clearer labeling and a bit more breadth in screw lengths, and I accept that edge-case sizes won’t be covered. But the fundamentals—fit, material quality, and everyday utility—are solid.

Recommendation: I recommend this kit to anyone who assembles or repairs flat-pack furniture more than once in a blue moon. It’s an inexpensive way to prevent stalled builds, replace fragile stock hardware with sturdier parts, and keep common sizes on hand. It won’t match every cam pocket under the sun, but for typical desks, dressers, cabinets, and shelving, it’s a reliable, time-saving addition to a home toolbox.
