Usos & Funciones
The core uses and functions of these nuts revolve around providing secure, anti-loosening fastening and auxiliary connection:
-
Secure Fastening: Lock and fix bolts, studs, or other threaded components to prevent loosening caused by vibration, load changes, or long-term operation.
-
Space-Saving Installation: The thin-type design enables fastening in narrow or confined spaces where standard-sized nuts cannot fit.
-
Precision Adjustment: Fine-thread structure allows for micro-adjustment of the fastening position, ensuring high-precision assembly requirements.
-
Auxiliary Connection: As coupling nuts (also called “joining nuts”), they can connect two externally threaded components end-to-end to extend the length of the threaded connection or transfer loads between them.
-
Corrosion Protection: El 304 stainless steel material protects the fastening structure from corrosion, ensuring stable performance in harsh environments.
Key Features
-
Premium 304 Stainless Steel Material: Possesses excellent corrosion resistance, rust resistance, and oxidation resistance, suitable for both indoor and outdoor environments, including mild corrosive scenarios.
-
Fine-Thread Design: Small thread pitch ensures precise meshing with fine-thread bolts/studs, enhancing fastening stability and enabling micro-adjustment.
-
Thin-Type & Flat Profile: Significantly thinner than standard nuts, minimizing the axial space occupied after installation, ideal for compact equipment and narrow installation areas.
-
Hexagonal Structure: Facilitates easy tightening and loosening with common tools (p.ej., wrenches), improving assembly efficiency.
-
Anti-Loosening Performance: The locking design (depending on the specific type, such as friction locking or mechanical locking) effectively prevents self-loosening under dynamic loads and vibration.
Ventajas
-
Superior Corrosion Resistance: 304 stainless steel outperforms carbon steel nuts in resistance to moisture, químicos, and atmospheric corrosion, extending the service life of the fastening system.
-
Space-Saving Efficiency: The thin-type design solves the fastening problem in confined spaces, expanding the application range of the nuts.
-
High Precision & Stability: Fine-thread structure ensures tight meshing, reducing the risk of gaps and displacement, and maintaining stable fastening performance for long periods.
-
Versatile Compatibility: Compatible with most standard fine-thread bolts, studs, and threaded components, enabling wide application across different industries.
-
Durable & Bajo mantenimiento: High material strength and wear resistance reduce the frequency of replacement and maintenance, lowering long-term operational costs.
