Product Description

The Flat Bottomed Large Plate Flange Nut is a meticulously engineered fastener that flawlessly merges the distinctive traits of flat-bottomed design, expansive plate, and flange structures. This innovative nut is extensively employed across diverse fields such as machinery, construction, and automotive manufacturing. Below is an in-depth exploration of its structural features, performance advantages, application scenarios, as well as guidelines for selection, installation, and maintenance.

Structural Characteristics

Flat Bottom Design: The nut's base is thoughtfully crafted to be flat, providing a generously smooth contact area with the connector's surface. This design effectively distributes pressure, mitigating localized stress concentrations, thereby reducing potential surface damage. Consequently, it enhances the stability of connections, ensuring that precision instruments and equipment maintain their surface integrity during nut installation without succumbing to excessive localized pressure.

• Large Plate Structure: The nut's top features a disc-shaped structure that significantly enlarges the contact area between the nut and tools such as wrenches. This design enhances the ease of installation and disassembly, especially in confined spaces or when high torque is necessary. For instance, in automobile engine compartments, where space is at a premium, these large flange nuts allow maintenance personnel to swiftly operate tools, facilitating efficient maintenance.

Flange Section: The nut's midsection elegantly extends outward to form a flange, often adorned with meticulously distributed holes or protrusions. These holes serve as installation points for positioning pins or auxiliary positioning anchors for other connection structures, refining positioning accuracy and reinforcing the connection strength between nuts and connectors. The protrusions augment friction with the connecting piece's surface, safeguarding against loosening in vibrating environments.

Performance Advantages

High Strength Connection: This specially constructed nut guarantees uniform stress distribution under substantial loads, thereby ensuring the connection's reliability and stability. In heavy machinery assembly, such as the integration of crucial components in large cranes, flat-bottomed flange nuts are invaluable in assuring the equipment's resilience against immense tensile and compressive forces, preventing loosening during operation.

Outstanding Anti-Loosening Performance: The snug fit between the flange and the connecting piece's surface, coupled with potential anti-loosening mechanisms like anti-loosening teeth or locking washers, effectively counters vibration and impacts. This greatly diminishes the risk of nut loosening. In railway track fixations, where vigorous vibrations occur during train operations, the flat-bottomed large plate flange nuts excel in meeting the stringent anti-loosening demands.

Exceptional Corrosion Resistance: Tailored materials and advanced surface treatments, like stainless steel or galvanizing and nickel plating, ensure robust corrosion resistance. This adaptability renders them ideal for harsh environments laden with humidity and corrosive gases. In marine engineering, where equipment endures prolonged seawater exposure, selecting suitable materials and surface treatments guarantees the nuts' long-term stability and operational reliability.

Application Scenarios

Mechanical Manufacturing: Employed in various machine tools and transmission equipment, they facilitate the secure connection and fixation of vital components, ensuring operational accuracy and stability. For instance, in the correlation between the spindle box and the bed of a CNC machine tool, flat-bottomed flange nuts deliver unwavering fastening force, enabling the spindle's high-precision operation.

Construction Engineering: Utilized for connecting and securing myriad components in expansive steel structures, bridges, and other monumental constructions, these nuts play a crucial role in ensuring the structural integrity and longevity of such edifices.
