The NRH 8601-80 Spring Flush Hinge is a premium self-closing hinge made of high-quality 304 stainless steel. Built with an integrated rebound spring mechanism, this hinge enables automatic door closing after opening, realizing hands-free rebound and keeping doors normally closed. Adopting vibratory polished finish, the surface is smooth, burr-free and wear-resistant, delivering excellent anti-rust and anti-corrosion performance. Suitable for cabinet doors, equipment enclosures, electrical boxes and outdoor cabinet doors, it ensures smooth operation, stable elasticity and long service life in frequent opening and closing scenarios.
The built-in high-toughness torsion spring maintains stable rebound force without loosening or fatigue after long-term use. Flush mounting design is easy to install with strong load-bearing capacity, perfectly matching wooden doors, metal doors and industrial equipment door panels.
Product Spotlight: NRH 8601-80 Self-Rebound Flush Hinge
NRH 8601-80 304 stainless steel spring flush hinge features precise integral forming and professional vibratory polishing treatment. The self-closing spring structure automatically rebounds to close the door tightly, effectively preventing dust, moisture and accidental opening. Smooth rotation without jamming, stable load-bearing and durable performance, ideal for indoor, humid and outdoor harsh environments.
Technical Specifications & Core Features
Precision engineered for strength and utility, the hinge is defined by these key attributes and reinforced by the 8 series collective advantages:
- Detachable (Lift-Off) Design – The removable stainless steel pin enables instant separation of door or panel from the frame without loosening any screws. Perfect for frequent maintenance or modular logistics.
- High-Grade 304 Stainless Steel Construction – Leaves, shaft, and rivet are all 304 SS, providing excellent rust and corrosion resistance suitable for outdoor, marine, and food processing environments.
- Substantial Load Rating – Rated for 14kg load capacity (reference value for a pair of hinges installed longitudinally), robust enough for server cabinets, electrical enclosures, and industrial guard doors.
- Vibratory Polished Surface Finish – Achieves a consistent semi-matte texture that improves cleanability, reduces friction, and enhances corrosion protection while eliminating burrs.
- Inherited 8-Series Robust Engineering
- Stainless Steel Shaft – Smooth rotation, wear-resistant and rust-free.
- Rivet-Fixed Anti-Detachment – The hinge pin is permanently riveted, preventing accidental pull-out even under heavy vibration.
- Quiet Low-Gap Operation – Tight tolerances reduce lateral movement and metal-to-metal noise, ensuring silent running.
- Uniform Force Holes – Optimised hole pattern distributes stress evenly across the mounting surface for secure fixing.
- Thickened Heavy-Duty Leaf – 2mm leaf thickness provides extra rigidity for high-cycle applications and heavier doors.
Precise Dimensions & Mounting Specifications
Engineered for seamless integration into standard and custom enclosures, the hinge features exact measurements and countersunk holes for flush screw installation.
- Overall Length (L): 75 mm
- Overall Width (W): 49.7 mm
- Leaf Thickness: 2.0 mm – robust load transfer
- Mounting Holes (per leaf): 4 x φ5.4 mm through holes with φ9.2 mm counterbores – compatible with M5 flat head screws for a flush, obstruction-free surface.
- Detach Mechanism: Removable hinge pin (tool-free extraction).
- Surface Treatment: Vibratory Polished – fine matte finish, easy to clean, highly resistant to fingerprints and corrosion.
The generous counterbores ensure flat head screws sit below the leaf surface, avoiding interference with internal components and granting a professional, industrial-grade appearance.
