How door and cabinet hardware is made
Indian hardware comes in three broad kinds. Cast brass knobs, pulls and lever handles are sand cast or forged, then machined, polished and lacquered or plated. Zinc die-cast and stamped steel pieces, including most hinges and tower bolts, are pressed or cast in volume and then plated or powder coated. Hand-forged iron hardware is heated and shaped on an anvil: strap hinges, latches, hooks and pulls with a hammered texture, finished in black powder coat, paint or wax.
Aligarh district in Uttar Pradesh has "Locks & Hardware" as its One District One Product, and its ODOP page lists hardware fittings. For hand-forged hardware we have found no official cluster source, so we name no town. TradeStat shows FY2025-26 exports, which are provisional, of US$75.9 million for hinges (HS 830210), US$211.4 million for fittings for buildings (830241) and US$65.0 million for fittings for furniture (830242).
Hardware is usually fitted to doors, drawers or cabinets made somewhere else, often to another country's sizes. That is why measurement matters more than looks.
What we check on door and cabinet hardware
| Check | How it is checked | What fails |
|---|---|---|
| Thread standard | Thread gauge on knob and pull fixings: 8-32 UNC for US cabinet work against metric M4, a common mix-up | Metric threads in a US order, or the reverse; screws will not engage |
| Screw length and count | Screws measured against the door or drawer thickness in the order; screws per pack counted | Screws too short to reach, or so long they mark the front; short count |
| Hole centres | Pull centre-to-centre measured with a gauge, against metric (such as 96 or 128 mm) or inch sizes in the order | Pull will not fit pre-drilled doors |
| Hinges | Leaf size, knuckle alignment, pin fit and play; door-hinge holes countersunk for the screw head; static load hung where the order sets one | Hinge binds or drops, screws sit proud, leaf bends under load |
| Lever handles | Spring return to level, play at the rose, spindle size and length for the door thickness | Handle droops, wobbles or the spindle is wrong for the lock |
| Hooks | Static weight hung for a set time; wall plate and screw holes checked | Hook bends or the plate cracks |
| Finish | Each piece compared with the approved finish panel in daylight; pieces from different lots laid side by side; cross-cut tape test on coatings | Shade differs between lots or between handles and hinges in one set; coating lifts |
Hand-forged iron hardware: agreeing what variation is allowed
Buyers choose hand-forged pulls and hinges because no two are identical. That makes the specification harder, because "handmade look" is not a measurement. Before production, agree limits in writing: the range of length and width, hammer texture density, twist count on twisted pulls, and the colour of the finish. Keep signed boundary samples, one at each limit.
At inspection we sort pieces against those boundary samples. Fixing points must not vary, even when the shape does: hole centres, thread size and screw seating are measured on every sampled piece. We also run a hand along edges and hook tips for burrs left by the forge, and look at waxed or lightly coated iron for rust starting in the hammer marks. For bathroom hooks and towel rails, see wall-mounted bathroom accessories, which covers their load and fixing kits.
Common defects in door and cabinet hardware
| Defect | Why it matters | Class |
|---|---|---|
| Sharp burr on a pull, hook tip or hinge edge | Cuts hands | Critical |
| Hinge or hook fails under the agreed load | Door or load falls | Critical |
| Lead in coating or substrate above the limit on children's furniture hardware | Illegal for children's products in the US | Critical |
| Wrong thread standard or hole centres | Cannot be fitted | Major |
| Finish shade differs between lots or within a set | Mismatched kitchen or door suite | Major |
| Lever handle does not return to level | Looks broken, wears the lock | Major |
| Short screw count | Customer cannot install | Major |
| Small polishing marks, slight texture variation within limits | Appearance only | Minor |
Standards and rules for door and cabinet hardware
- EN 1935 covers single-axis hinges. It is on the European Commission's list of harmonised standards for construction products, so hinges sold for fire or smoke doors need a declaration of performance and CE marking. Ask for the declaration and the notified body certificate. See CE and UKCA marking.
- EN 1906 covers lever handles and knob furniture; EN 15570 covers the strength and durability of furniture hinges, and EN 15338 of drawer slides and other extension elements.
- ANSI/BHMA A156.9 covers US cabinet hardware, including hinges, knobs, pulls, catches and drawer slides, in grades; A156.1 covers butts and hinges for doors.
- CPSIA. Hardware on children's furniture is part of a children's product: lead content and lead in paint limits apply. See CPSIA children's products and children's furniture.
- California Proposition 65 for lead in brass knobs, pulls and handles. See Prop 65.
Cycle and corrosion tests are lab work; we pull and seal samples through lab testing coordination.
Packing, transit and your purchase order
Polished brass scratches against itself, so each piece should be bagged or wrapped separately. Sets should be packed per door or cabinet with their screws in a sealed bag, so the installer finds everything in one box. Forged iron needs dry packing and VCI paper. When hardware ships inside furniture, we check it is fitted or packed in the right carton; see furniture inspection.
Put these in your purchase order:
- Drawing with size, hole centres, thread standard and screw length for the door or drawer thickness.
- Material, finish, finish panel and coating thickness.
- For hand-forged items, written limits of variation and signed boundary samples.
- Load for hinges and hooks, and any EN or BHMA grade with its test report.
- For fire doors, the declaration of performance; for children's furniture, lead test reports.
- Screw count per set, packing per set, labels and carton marks.
