Cabinet Hinge Screw Sizes: Finding the Right Replacement Fastener
#8 × 3/4" or #8 × 1" flat-head wood screws. Door hinges use #9 × 1" for standard holes and one #9 × 3" or #10 × 3" long screw per hinge leaf to anchor into the framing stud.
You opened a cabinet door and a screw fell out — or worse, the screw is still in there but just spinning. Now you're staring at a tiny hole in a hinge leaf wondering what size screw replaces it. Good news: hinge screws are nearly universal, and the right size is probably sitting in a box at your local hardware store right now. Here's how to find it.
The Two Types of Hinge Screws (And Why They Differ)
There are two different jobs hinge screws do, and they call for two different screws:
- Short screws go into the hinge leaf holes that land on cabinet face frame or door jamb wood — they just need to hold the leaf flat. These are typically
#8 × 3/4"to#8 × 1". - Long screws (on door hinges) are the load-bearing anchors. At least one hole per leaf is aligned to hit the structural framing stud behind the jamb. These need to be
#9 × 3"or#10 × 3"to reach through the jamb into the king stud.
If your door hinge is loose and wiggling, the long screw is what's failed — and the fix is almost always to swap the stripped short screw for a 3-inch version.
Cabinet Hinge Screw Size Chart
The table below covers the most common hinge categories. Sizes are typical industry standards — always verify against your hinge's actual hole diameter before ordering a bag of 100.
| Hinge Type | Screw Gauge | Length (standard) | Head Type | Notes |
|---|---|---|---|---|
| Kitchen cabinet face-frame hinge | #8 | 3/4" – 1" | Flat (countersunk) | Most common. Fits 3/32" counterbore holes in hinge leaf. |
| Overlay / frameless cabinet hinge | #8 | 5/8" | Flat or pan | Thin panels — keep length short to avoid blowout. |
| Concealed (Euro/cup) hinge | 3.5mm × 16mm | 16mm | Pan (Rafix/Confirmat) | NOT a standard wood screw — use Hettich/Blum spec screw. |
| Interior door hinge (3.5") | #9 | 1" (standard) + 3" (stud) | Flat | One 3" screw per leaf into the stud carries the door weight. |
| Exterior door hinge (4") | #12 | 1.5" (standard) + 3" (stud) | Flat | Heavier door, larger gauge. Security note: all holes should anchor into framing. |
| Piano (continuous) hinge | #8 | 1/2" – 3/4" | Flat or oval | Hole spacing ~2–3". Use oval head for a finished look. |
European-style cup hinges (Blum, Hettich, Grass) do NOT use standard wood screws. Their mounting plates use Rafix or Confirmat-type machine screws — typically 3.5 × 16 mm. Using a standard #8 wood screw in these holes will strip the hole and void the adjustment mechanism. Match to the hinge manufacturer's spec sheet.
How to Identify Your Hinge Screw Size
You have a hinge and the screw is stripped, missing, or broken. Here's the fastest path to the right replacement:
Method 1: Measure the Existing Screw
If you have a working screw from the same hinge, measure it with calipers:
- Shank diameter across the unthreaded shoulder (just below the head). This gives you the gauge number. A #8 shank is
0.164"(4.16 mm); a #10 shank is0.190"(4.83 mm). - Length from the underside of the head to the tip. For a flat-head screw, measure from the top of the head to the tip (the head is counted in the length).
Identify Your Screw Gauge Instantly
Enter the shank diameter in our free identifier tool and it will tell you the exact #-gauge or metric designation.
Open Identifier →Method 2: Measure the Hinge Hole
Hinge leaf holes are sized for specific gauges. The counterbore (the cone-shaped recess around the hole) tells you the gauge:
- Counterbore diameter ≈ 5/16" (8 mm): #8 screw
- Counterbore diameter ≈ 3/8" (9.5 mm): #10 screw
- Counterbore diameter ≈ 7/16" (11 mm): #12 screw
No calipers? Use a coin or pencil trick. A standard pencil eraser is 6.5 mm across — close to the #8 screw hole but slightly smaller than a #10 hole. If the pencil eraser drops through the counterbore with a gap, you likely have a #10 or larger.
Method 3: Look Up the Hinge Manufacturer's Spec
Brand-name hinges (Stanley, Baldwin, Schlage, SOSS, Blum) list the required screw in their spec sheets. Search "[brand] [hinge model] spec sheet screw size." Most PDF spec sheets are freely available and show the exact gauge and length.
Fixing a Loose or Stripped Hinge
If the hinge is wobbly because a screw hole is stripped, your options in order of permanence:
Option 1: Longer Screw (Best Fix, Usually)
Replace the stripped screw with a longer one — typically going from #9 × 1" to #9 × 3" so it bites into the stud behind the jamb. This is the fix a carpenter would do. The screw needs to hit fresh wood, not the same stripped hole.
On a door jamb hinge, one hole per leaf is specifically positioned to hit the king stud. Look for the hole that lines up closest to the center of the jamb — that's your stud hole. Always use the 3" screw in that specific position, not as a random swap.
Option 2: Wooden Toothpick and Glue (Same-Size Screw Fix)
If you need to keep the same screw position (e.g., the screw is stripped but you can't use a longer one), fill the hole:
- Remove the screw.
- Coat 2–3 wooden toothpicks with wood glue and push them into the hole.
- Break them off flush and let the glue dry for 1 hour.
- Drive the original-size screw back in — it will bite into the fresh wood.
Option 3: Move the Hinge (Last Resort)
If the hole is too damaged to hold any repair, shift the entire hinge up or down by 1/8"–1/4" on the jamb, then chisel a new mortise and drill fresh pilot holes. This is a full rehang but guarantees solid mounting.
What to Buy at the Hardware Store
For a standard interior door or cabinet hinge replacement, you want:
- Cabinet hinges:
#8 flat-head coarse-thread wood screws, 1" length. Phillips or square drive. A box of 100 costs ~$6 and will last years. - Door hinges (standard holes):
#9 flat-head wood screws, 1" length. - Door hinges (stud-anchor screw):
#9 or #10 flat-head wood screws, 3" length. Buy 1 per hinge — one per leaf needed at that specific stud-aligned hole.
If you're buying at a big-box store, look in the door hardware or fastener section. Packages labeled "hinge screws" are almost always #9 × 1" with the flat-head profile — confirm the gauge matches your hinge holes before buying.
Metric Cabinet Hinges
European-manufactured kitchen cabinets (common in IKEA, many imported flatpack brands) may use metric hinge screws. The most common are:
| Metric Size | Imperial Equivalent | Common Use |
|---|---|---|
| 3.5 × 16 mm | ~#6 × 5/8" | Blum/Hettich cup hinge mounting plates |
| 4.0 × 25 mm | ~#8 × 1" | European face-frame hinges, drawer glides |
| 5.0 × 40 mm | ~#10 × 1.5" | Heavy frameless cabinet door hinges |
If your cabinet is European-made and the screws measure in whole millimeters (3.5, 4.0, 5.0 mm shank), buy metric fasteners rather than trying to force an imperial #8 or #9 into a metric hole. The diameter difference is small but the thread pitch is different — an imperial screw will cross-thread.
Recommended Tool
Digital Caliper — 6" / 150mm
The fastest way to measure any screw shank diameter and confirm your gauge. A quality stainless steel digital caliper reads to 0.01 mm and eliminates guessing — essential for matching metric and imperial hinge hardware.

- What size screws do standard cabinet hinges use?
- Most cabinet face-frame hinges use
#8 × 3/4"or#8 × 1"flat-head coarse-thread wood screws. The hinge leaf hole diameter tells you the screw gauge — measure it with calipers or use our identifier tool. - What size screws do door hinges use?
- Standard interior door hinges (3.5") use
#9 × 1"screws for typical holes and one#9 × 3"screw per hinge leaf that anchors into the stud. Exterior doors (4" hinges) often step up to#12 × 1.5"for the standard holes. - Are hinge screws a special thread or standard?
- Most hinge screws are standard coarse-thread wood screws — not special. A #8 flat-head wood screw from any hardware store fits. European concealed/cup hinges are the exception: they use metric machine screws.
- Can I use a longer screw to fix a loose door hinge?
- Yes — this is the standard repair. Replace the worn screw with a 3"
#9or#10wood screw so it reaches the stud behind the door jamb. Don't put the same gauge in a stripped hole without filling it first with wooden toothpicks and wood glue.
