TDCHINGES 30 Pack Rounded Satin Door Hinges Brushed Nickel 3.5 Inch Interior 3 1/2 Inch 5/8" Radius Corners Iron Bifold Silver Residential Bed Room Hinge for Doors Hardware Controls House Decor Accessories

Why I reached for these hinges

I had a whole-house hardware refresh on my plate: swap dated brass hinges for a clean, modern satin nickel, keep the doors in place, and avoid fiddly re-mortising. I picked up the TDCHINGES 3.5-inch rounded hinges in the 30-pack to handle bedrooms, bathrooms, closets, and a few built-ins. The short version: they did exactly what I wanted—standard fit, clean look, smooth motion—without turning the project into a weekend-long wrestling match.

Build and finish

These are full-mortise, plain-bearing hinges with 5/8-inch radius corners, six screw holes per leaf, and removable pins. The leaves feel properly flat and consistent, not wavy or bowed, and the barrels line up true out of the box. The satin nickel finish is even and low-sheen—no glittery sparkle, just that soft brushed look that hides fingerprints well. Across my pack, color tone and grain direction matched, so doors in the same hallway didn’t end up looking mismatched.

They’re plain-bearing, not ball-bearing, which is what you want for most interior 1-3/8-inch doors. If you’re hanging heavy solid-core slabs or commercial doors that see serious traffic, ball-bearings are worth considering. For standard residential doors, these plain bearings run quietly and predictably.

One small note: there was a very light protective oil at the knuckles on a few pieces. Wiping with a microfiber cloth before install kept it from touching paint. It’s common and not a defect—just something to do first.

Sizing and fit

If your doors are prehung with 3.5-inch hinges and 5/8-inch radius corners (very common on interior doors), these drop right in. The hole pattern matched the legacy hinges in my case, so I didn’t need to fill or re-drill. The leaves sat flush in the existing mortises without rocking, and the barrel projection was close to my originals. On one slightly out-of-square frame, I adjusted the reveal by loosening all three hinges, nudging the door in place, and retightening—standard fare when you modernize older houses.

A reminder on sizing:
- 3.5-inch is typical for 1-3/8-inch interior doors.
- 4-inch hinges are more common on 1-3/4-inch doors.
- The 5/8-inch radius corners matter. If your mortises are square- or 1/4-inch-radius, you’ll need to round or square accordingly. A corner chisel or a hinge template/router jig makes that painless.

Installation experience

I swapped hinges one leaf at a time with the door in place: back out three screws on the jamb leaf, swap, then do the door leaf—no shims, no lifting. It’s the least disruptive method and keeps alignment in the ballpark from the start.

Included screws were color-matched and I appreciated that the pack had both standard and a few longer screws. I used the longer screws on the top hinge into the stud to add a bit of sag resistance, especially on the heavier doors. Threads are clean, heads fit a standard Phillips bit, and the finish didn’t flake under the driver.

Installation tips that helped:
- Pre-drill pilot holes if you’re going into hardwood or old jambs—saves screw heads and your patience.
- Use the right bit and fresh tips to avoid cam-out on the last quarter turn.
- If old holes are stripped, toothpicks and wood glue still work magic. Let it cure before driving new screws.
- Paint ridges in mortises keep hinges “proud.” A sharp chisel or a card scraper cleans that up fast.
- Replace hinges top and bottom first, then do the middle. If the door shifts, loosen all three, center the reveals, and snug them up in sequence.

As for the pins: they’re removable. Tap from the bottom with a small punch or nail set. That’s useful if you want to pull a door without touching screws, or if you’re painting.

Performance and feel

Once installed, the doors swung quietly and returned to neutral without dragging the jamb. There’s a slightly damped feel to the motion—no gritty scrape, no binding. I didn’t need lubricant out of the box, but a drop of dry lube at the knuckle never hurts down the line.

The manufacturer notes up to 270 degrees of rotation. In practice, most interior doors will hit trim or knobs long before that. Still, it means the leaves can fold flat on themselves without stressing the knuckle, which is handy on bench applications, shutters, or where doors need to swing fully clear.

Weight-wise, these are not feather-thin. I didn’t measure with calipers, but compared to the older budget hinges I pulled, these felt at least as stout. I didn’t see leaf deflection under normal use, and screw hole tooling was clean—no burred edges to catch.

Use cases beyond doors

• Built-ins and wardrobes: The low-sheen finish looks right at home and resists the smudgy look some polished finishes get.
• Utility doors and light shutters: Full mortise, smooth motion, and removable pins make them versatile.
• Sheds or outbuildings: If sheltered and not in a humid/salty environment, they’ll last fine. For exposed exterior use, I’d step up to stainless or at least a corrosion-rated hinge.

The 30-pack format is ideal for a whole-house refresh. With three hinges per door, you can do ten doors and still have a few spares for future projects.

Small drawbacks and caveats

• Plain bearing limits: For heavy solid-core or high-use commercial doors, ball-bearing hinges wear longer and run smoother under load.
• Corner radius mismatch: If your existing mortises are square or 1/4-inch radius, plan for a bit of fitting. Not a flaw—just a compatibility detail to confirm before ordering.
• Protective oil residue: Wipe hinges before install so you don’t mark fresh paint or primed jambs.
• Not security-pin hinges: For outswing doors, choose a hinge with non-removable pins or security tabs. For interior use, these are perfect as-is.

Durability and maintenance

After install, I cycled each door repeatedly and listened for chatter or squeak—none. A month in, still quiet. Plain bearings can dry out over years; a tiny touch of silicone or PTFE lube at the knuckle fixes that in seconds. The satin nickel finish has held up to fingerprints and the occasional bump from a vacuum or laundry basket without scratching or discoloration.

If you’re mixing these hinges with hardware from multiple brands, note that “satin nickel” can vary slightly in tone across manufacturers. Within this pack, the finish was consistent; just compare to your levers and strike plates before committing to a whole-house swap.

Value and packaging

Buying hinges one or two at a time adds up fast. This bulk pack brought the per-hinge cost down to a very palatable number, and I didn’t need to make multiple runs when I discovered one extra closet door I’d forgotten. The hinges arrived protected, and the finish was unblemished across the lot.

Practical checks before you start

• Confirm: 3.5 x 3.5 inches, 5/8-inch radius corners.
• Count: three hinges per standard interior door.
• Tools: #2 Phillips, hand screwdriver for final snug, small punch for pins, chisel or corner chisel if you need to match radii.
• Prep: wipe hinges to remove any light oil; vacuum mortises; test one door before committing to the rest.

Recommendation

I recommend these TDCHINGES 3.5-inch rounded hinges for interior door updates, especially whole-home projects where consistency, fit, and cost matter. They install cleanly into standard 5/8-inch radius mortises, run quietly, include color-matched screws (with a few longer ones that are genuinely useful), and the satin nickel finish looks tidy without drawing attention. They’re not the choice for heavy-duty or exterior, but for typical residential doors they hit the right balance of quality and value. If your mortise radius matches and you want a straightforward, reliable hinge in bulk, this pack is an easy yes.
