NRH 8403-38 Small Stainless Steel Hinge | SUS 304 for Instrument Cases & Panels

NRH 8403-38 Stainless Steel Butt Hinge - SUS 304, Vibratory Finish, 38mm Compact Size

The NRH 8403-38 is a precision‑engineered, compact stainless steel butt hinge designed for applications where space is limited but reliability cannot be compromised. Expertly crafted from SUS 304 stainless steel with a smooth vibratory finishing, this hinge delivers excellent corrosion resistance, durability, and a clean professional look. Weighing only 12g yet capable of supporting a 98N (10kg) bearing load, it is the perfect solution for lightweight doors, lids, and access panels on precision equipment.

The hinge measures 38mm in length and 30mm in width (material thickness: 0.8mm), with 4x Ø3.4mm mounting holes for accurate and secure screw installation. Its all‑stainless construction ensures smooth, consistent, and wobble‑free swinging motion over time.

The NRH 8403-38 is manufactured by NRH Box Hardware - a trusted industry leader since 1996 - under an ISO 9001:2000 certified quality management system. Regarding international compliance (SGS, REACH, RoHS, SVHC), these standards can be supported based on customer requirements and applicable costs - please contact us for specific certification needs. We offer flexible OEM and ODM services to meet your specific design requirements.

Primary Applications - Small Scale & Precision

• Small instrument and device cases: Housings for portable meters, sensors, communication devices, and field test kits
• Electrical and electronic enclosures: Access doors on small control boxes, modular panels, terminal boxes, and network device casings
• Precision cabinetry and furniture: Doors for laboratory cabinet drawers, display case components, and high‑end model enclosures
• Light‑duty industrial panels: Inspection covers and small doors on machinery or equipment

How It Works - Simple Pivot Mechanism

As a classic butt hinge, it operates on a simple and reliable pivot mechanism. The two interlocking leaves, made of SUS 304, are joined by a central pin. One leaf fastens to the moving panel (door or lid), the other to the stationary frame. The pin acts as the rotational axis, allowing for a smooth, consistent, and wobble‑free swinging motion for opening and closing. The stainless steel construction ensures this action remains reliable over time, even in demanding environments.
