Why I swapped my whole house to these hinges

I recently replaced every interior hinge in a mid-2000s house with a 30-pack of TDCHINGES 3.5-inch matte black hinges. The goal was basic: update the look from aging brass, tighten up a few sagging doors, and do it without overspending. After living with the new hinges for several weeks, I’m impressed by how straightforward the upgrade was and how consistently these budget-friendly hinges performed.

What you’re getting

• 30 full-mortise, 3.5 x 3.5-inch hinges with 5/8-inch radius corners
• Plain bearings (not ball-bearing)
• Removable pins (tapped out from below)
• Six screw holes per leaf
• Matte black finish
• A full set of color-matched screws, including several longer screws per hinge set

The 30-pack is just right for a typical home if you’re running three hinges per door—think roughly 10 standard interior doors. The inclusion of longer screws is more than a convenience; they’re invaluable for pulling a door back into alignment and anchoring hinges more securely to the framing.

Build quality and finish

The hinges are iron with a matte black coating that reads as contemporary without looking glossy or cheap. In my box, the finish was uniform across all pieces—no dings, no thin spots. It’s not the ultra-textured “architectural” matte you find on premium hardware, but it’s consistent and good-looking installed. The pin heads and knuckles align neatly, and the edges are clean with no burrs.

A note worth planning for: several hinges had a light protective oil from the factory. If you’re installing against white or freshly painted jambs, a quick wipe-down with a microfiber cloth and a bit of mineral spirits or denatured alcohol prevents smudges. It’s a small step that keeps the finish looking crisp.

Fit and compatibility

These are standard 3.5-inch residential interior hinges with a 5/8-inch radius. If your existing doors are mortised for square-corner or 1/4-inch radius hinges, you’ll need to adjust the mortises. Most newer pre-hung interior doors use 5/8-inch radius corners, so for those, this is a direct swap.

The hole pattern matched every door and jamb I encountered. I was able to replace hinges without rehanging doors—swap one hinge at a time, top to bottom, and everything lines up. The leaf thickness is in line with typical builder-grade hardware, so reveals didn’t change meaningfully. On one older solid-core door, I did use a hinge bender to add a hair more clearance at the latch side, but that was a house-settling issue, not a hinge tolerance problem.

Installation experience

Installation was refreshingly uneventful. Here’s what worked well:

• Replace one hinge at a time with the door closed. This avoids fighting gravity and keeps reveals consistent.
• Pre-drill pilot holes for the longer screws, especially into the jamb/stud side. It reduces the chance of splitting or cam-out.
• Use at least one long screw on the top hinge into the stud. It’s a simple upgrade that prevents door sag over time.
• Keep your driver bit fresh. The black-coated screw heads look great, but like any painted/phosphate finish, they’ll show a slip of the bit.

The pins are removable: tap a small nail or punch into the hollow end from below to drive them out. This is handy for painting, transporting doors, or pinning two leaves together during alignment checks. Because the pins are removable and there’s no non-removable security feature, these are not suited for outward-swing exterior doors from a security standpoint.

Performance and day-to-day use

Once installed, the hinges operate quietly and smoothly. Plain-bearing hinges don’t have the silky “float” of a ball-bearing hinge on heavy doors, but for most hollow-core and standard-width solid-core interior doors, I had no noise or sticking. After several weeks of daily use, no squeaks. If one develops eventually, a drop of dry PTFE or silicone lubricant at the knuckle usually fixes it.

Swing is typical of interior butt hinges. The marketing claims 270 degrees, but in a real doorway you’ll be limited by casings and walls long before that. The leaves will fold flat against each other if free, but plan for normal interior door travel.

The finish has held up to hands, bags, and casual bumps without chipping. The matte texture is fingerprint-friendly—it hides smudges more than it invites them. On a test piece, I did manage to mark the finish by intentionally slipping a driver bit across a screw head; under normal use, the screws and hinge leaves have stayed presentable.

Where these make sense—and where they don’t

These hinges shine in whole-home refreshes, rental turnovers, and light to medium-duty interior applications. They’re a strong match for:

• Hollow-core and standard solid-core interior doors
• Quick updates from bright brass or nickel to a contemporary matte black
• Projects where you want consistent fit and a value pack with all the screws you need

They’re not the right pick if you need:

• Ball-bearing hinges for heavy, oversized, or high-traffic doors
• Fire-rated or spring hinges for code-specific locations
• Exterior-grade hardware with non-removable pins and corrosion-resistant materials
• Square-corner or 1/4-inch radius replacements without mortising work

Small snags and how I addressed them

• Protective oil residue: Wiped each hinge before install; no more smudges on white jambs.
• Slightly out-of-true framing: Used the included long screws to pull the jamb true at the hinge locations; a hinge bender fine-tuned door-to-jamb reveals.
• Old stripped screw holes: Toothpicks and wood glue, let cure, then drive screws. Rock solid.
• One stiffer knuckle: Worked the hinge a few times off the door and added a drop of dry lube. Smooth afterward.

None of these were dealbreakers or unusual for a project involving existing doors and frames.

Practical tips for a clean install

• Verify your mortise radius. These are 5/8-inch radius; check an existing hinge with a template or a coin (a quarter is close to 1/4-inch radius for quick comparison—not exact, but a useful sanity check).
• Label hinges as you unpack. Keep pairs together; it speeds up a whole-house swap.
• Use the long screws strategically. Top hinge into the stud, and one long screw per middle/bottom hinge if a door needs persuasion.
• If you’re switching finishes, plan to touch up paint around the leaf outline—different leaf corners can reveal old finish lines.

Value

Price-wise, the per-hinge cost in this 30-pack is hard to beat, especially once you add up the included screws. You’re paying for a reliable, standard-spec hinge with a widely appealing finish, not premium bells and whistles. For most interior doors, that’s exactly what you want.

The bottom line

TDCHINGES 3.5-inch matte black hinges deliver the fundamentals: consistent sizing, a clean modern finish, smooth operation, and a complete hardware kit that simplifies installation. They’re a practical way to refresh a whole home without fighting with odd hole patterns or flimsy leaves, and they include small but meaningful touches—like long screws—that help correct common door issues during the swap.

Recommendation: I recommend these hinges for interior residential projects where you want a cohesive matte black look, predictable fit, and solid day-to-day performance at a reasonable cost. If you’re hanging unusually heavy doors or need specialty features (ball bearings, fire rating, non-removable pins), look elsewhere. For everything else, this 30-pack is a dependable, budget-friendly choice that installs easily and looks the part.
