Product Description
Black Oxide Flange Blind Nut, Single Through Hole Flange Lock Nut
Product Overview
The Black Oxide Flange Blind Nut is a high-precision industrial fastening component integrally manufactured from premium carbon steel with professional black oxide surface finishing. Featured with a unique single through blind hole structure, one end is fully closed while the other end is designed with standard threaded holes, paired with an integrated flange limiting structure. This multi-functional lock nut combines reliable locking performance, dustproof protection, anti-loosening and anti-slip advantages. Boasts stable structural rigidity, high machining accuracy and excellent wear resistance, it is a universal and durable fastener widely applied in mechanical equipment, automation tooling, hardware facilities and various industrial assembly scenarios.
Core Product Features
Premium Black Oxide Anti-Corrosion Treatment
The surface adopts fine black oxide finishing to form a dense, uniform and firm protective film. This treatment effectively isolates air, moisture and tiny corrosive substances, preventing oxidation, rust and surface discoloration during long-term service. It significantly enhances the wear resistance and environmental adaptability of the nut, extending the service life in indoor and mildly humid industrial working conditions.
Single Through Blind Hole Dustproof & Anti-Loose Structure
Different from ordinary through-hole flange nuts, the single-end closed blind hole design effectively blocks dust, impurities and water vapor from entering the thread interior. It avoids thread clogging, scale accumulation and corrosion problems, fully protects the matching screw rod end from abrasion and damage. The structure effectively prevents component loosening and falling off during equipment operation, greatly improving assembly tightness and overall structural stability.
Integrated Flange Design with Uniform Stress Bearing
Equipped with a widened integral flange disc, the nut provides a larger pressure-bearing area compared with standard nuts. It disperses fastening pressure evenly during installation, effectively avoiding indentation and damage to the workpiece surface. The anti-slip and anti-offset flange structure eliminates the need for additional gaskets, simplifying the assembly process, improving installation efficiency and strengthening the overall fastening firmness.
Precision Thread Machining for Smooth Fitting
Adopting professional precision thread rolling technology, the threads feature standard tooth shape, uniform pitch, smooth surface and no burrs or defective teeth. The threads achieve tight and smooth meshing with matched screws, supporting easy installation and disassembly. It maintains stable locking force after repeated disassembly and assembly, not easy to slip or lose efficacy, with high precision and strong compatibility for standard industrial fastener matching.
Application Scenarios
This black oxide flange blind lock nut is widely suitable for machinery manufacturing, automation equipment, precision tooling fixtures, electromechanical hardware, precision instruments and mechanical supporting facilities. It is specially applicable for structural connection parts that require dust protection, anti-vibration and anti-loosening locking, serving as an essential core fastener for equipment assembly, installation and daily maintenance.
