Amazon Basics Interior Door Hinge, Rounded, 3.5 x 3.5 Inch, Satin Nickel - Pack of 18

Why I swapped an entire house of hinges

I recently spent a weekend refreshing the hardware in a 90s-era home—doorknobs, latches, and, critically, hinges. Rather than hunt down individual pairs, I went for an 18-pack of Amazon Basics 3.5-inch interior hinges in satin nickel. The goal was straightforward: consistent finish across the house, smooth operation, and a simple retrofit without reshaping every mortise. After installing them on a dozen interior doors, here’s how they performed and what to expect.

What you get

• Eighteen 3.5 x 3.5-inch rounded-corner hinges, steel with a satin nickel finish
• 108 matching screws (six per hinge)
• Standard interior hinge proportions for typical 1-3/8-inch-thick doors

Nothing fancy in the box—just uniform hardware ready for a bulk swap. The satin nickel finish is even and low-sheen, pairing well with most brushed or matte door hardware.

Design and build quality

These are plain-bearing, steel hinges targeted at interior doors. Out of the box, the knuckles were aligned, the leaves were flat, and the finish was consistent across all units. The rounded corners are the key design choice: they make retrofits easy if your existing mortises are already radiused. If you’re coming from square-corner hinges, you’ll either need to round the mortise corners or choose a square-corner alternative.

The satin nickel coating has the right amount of grain to hide fingerprints and minor scuffs. It isn’t flashy, but it looks clean and contemporary once installed. I checked for slop at the pivot and found only a hair of lateral play—typical for non–ball bearing hinges and acceptable for interior duty. The pins seated snugly, and rotation felt smooth without gritty spots or tightness.

Installation: fast if you prep correctly

I replaced hinges on each door one at a time without removing the door from the frame—top hinge first, then middle, then bottom. This keeps alignment intact and avoids wrestling a door solo.

A few tips from the install that will make your life easier:
- Match your hinge size and corner style. 3.5 x 3.5 refers to the size of the open hinge. These worked perfectly for standard interior doors but won’t fit 4-inch exterior mortises.
- Check mortise depth. These leaves sat flush in the existing mortises. If yours sit proud, a few passes with a chisel or router depth stop solves it. If they recess below flush, shim with card stock or veneer to maintain a proper reveal.
- Use pilot holes. The supplied screws bit cleanly into both jambs and stiles once I predrilled with a properly sized bit. Skipping pilot holes on older jambs is asking for a split.
- Consider reinforcement. For heavier solid-core doors, I like to replace one top-hinge screw on the jamb side with a longer screw that anchors into the stud. The screws included are standard interior length; they held well on hollow-core doors and light solids, but reinforcement improves long-term sag resistance.

Across the house, hole spacing lined up with existing mortises, and the rounded corners sat neatly. I didn’t have to enlarge or shift any holes. All screws were properly threaded and finished; I didn’t encounter stripping or head deforming when using a hand driver and a clutch-controlled drill.

Performance and feel

Once installed, the doors swung freely and quietly. There’s no self-closing or detent behavior—just a predictable swing that stays where you leave it, assuming your door and jamb are plumb. On a couple of older frames with a slight bow, I used the standard tricks to tune the reveal: swapping in a thin shim behind a leaf or slightly bending a leaf with a hinge adjuster to nudge the alignment. The hinges accepted those adjustments without binding.

Over the following weeks, operation remained smooth. No squeaks emerged, and the pins didn’t walk upward under use. If you do encounter a squeak down the road, a drop of light oil on the knuckle seam will quiet it; plain-bearing hinges benefit from occasional lubrication in high-use areas.

Finish durability

Satin nickel is a practical choice for interior hardware. It hides smudges, resists minor wear, and blends with a wide range of lever and knob finishes. I installed these in bedrooms, bathrooms, and closets; the finish hasn’t marred from incidental contact with rings or belts near the hinge edge. No flaking or discoloration showed up during installation, even when I had to back screws out and re-seat them. For bathrooms with regular steam, they’ve stayed clean—no early rust spots or pitting.

Fit and compatibility notes

• Size: 3.5 x 3.5 inches is the standard for most interior doors in North America. If your existing hinges measure 4 inches, these aren’t a match.
• Corner style: These are rounded. If your door and jamb were cut for square corners, plan to either round the mortise corners or select square-corner hinges to avoid extra work.
• Door weight: Ideal for hollow-core and lighter solid-core interior doors. For heavy, tall solid-core doors, I prefer ball-bearing hinges for longevity and effortless swing.
• Pin style: The pins seated securely and didn’t drift during use. I didn’t need to remove them for this install and can’t comment on ease of removal.
• Clearances: With the leaves sitting flush, gaps around the door stayed even. If your door rubs at the latch side after swapping, check for mortise depth mismatches or sag; hinge shims or a longer anchoring screw usually corrects it.

Value

Buying hinges in bulk is where this pack shines. Per hinge, the cost is hard to beat, and more importantly, the quality is consistent across the entire lot. If you’re rehabbing an entire home, a rental unit, or multiple rooms, the uniform finish and dimensions make the job predictable. You won’t get the ultra-tight tolerances or silky action of premium ball-bearing hardware, but for standard interior use, these deliver reliable performance at a sensible price.

Where these hinges make the most sense

• Whole-home refreshes where you need consistent finish and fit on many doors
• Rental turnovers and light renovation work with tight timelines
• Upgrades from dated brass to a modern satin nickel look without re-routing mortises
• Projects where you want pre-matched screws and a straightforward install process

Where I’d look elsewhere

• Heavy solid-core or oversize doors that see constant high-traffic use—ball-bearing 3.5-inch or even 4-inch hinges will run smoother for longer
• Historic doors with square-corner mortises if you’re trying to avoid any chisel or routing work
• Exterior doors—use appropriately rated, larger, and more robust hinges for that application

The bottom line

These Amazon Basics hinges did exactly what I needed: uniform fit, smooth swing, and a clean satin nickel finish across a whole house, without surprise rework. Installation was uneventful—in the best way—and the included screws were sufficient for a secure set. They’re not premium architectural hardware, and there’s a touch more play than you’d find on high-end ball-bearing hinges, but for interior doors they’re solid, quiet, and dependable.

Recommendation: I recommend these hinges for anyone updating multiple interior doors who wants a budget-friendly, consistent, and straightforward solution. They’re a practical pick for standard-weight doors, especially if your mortises are already cut for rounded corners. If you’re dealing with heavy doors or need square corners, choose hardware tailored to those demands; otherwise, this pack is a reliable, no-fuss upgrade.
