Product Applications

Product Description

 

First, the main functions and uses
Connection function: The main purpose of the nut is to connect more than two objects. By wrapping a nut around a bolt or screw, two objects can be firmly joined together and are suitable for different materials such as metal, wood, and plastic.
Quick Disassembly: The nut is designed so that the attached parts can be easily and quickly disassembled, making it easy to repair or replace the parts, saving time and money.
Adjust the tightness: By rotating the nut, you can adjust the tightness of the bolt or screw, thus changing the tightness of the connection, which is very useful for machines and devices that require regular maintenance.
Anti-loosening function: The nut can be tightly locked on the bolt or screw, preventing the connector from loosening in vibration or movement, ensuring the safety of the machine and device.
Load distribution: The nut can distribute the load, evenly distribute the load along the bolt or screw, reduce the impact of load excursion, and make the structure more stable.
II. Classification and Characteristics
There are many ways to classify nuts, and here are the main classification methods and corresponding characteristics:

Classification by material:
Carbon steel nut: a common nut material, suitable for general mechanical fastening.
Stainless steel nuts: strong corrosion resistance, suitable for wet, corrosive environments.
Non-ferrous metal nuts: such as copper nuts, which have the characteristics of corrosion resistance, high temperature resistance, strong thermal and electrical conductivity, etc., and are widely used in faucets, valves, electrical switches, mold injection molding and other fields.

Classification by shape:
Hexagon nut: Hexagonal in shape, it is the most common type of nut and is easy to tighten and loosen with tools such as a wrench.
Hexagonal Cap Nut: The end of the external thread is not exposed, and the top surface is in the shape of a cap, which is suitable for occasions where the external thread needs to be hidden.
Welded nut: There is a raised part on the support surface, which can be welded on the steel plate for use, and the connection fastening effect is good.
Slotted nut: groove the surface of the nut for use in specific occasions, such as with screw holed bolts and cotter pins to prevent the bolt from rotating relative to the nut.
Special shape nuts: such as four-jaw nuts, screw-in safety nuts, eyebolt nuts, etc., suitable for fastening needs in specific occasions.
Classification by function:
Self-locking nut: It can be self-locking by friction to prevent loosening caused by vibration and other reasons.
Anti-loosening nut: It has an anti-loosening function and is achieved through different mechanisms (such as mechanical anti-loosening, riveting anti-loosening, friction anti-loosening, structural anti-loosening, etc.).
Lock nuts: such as root nuts, locknuts, etc., which are used for locking needs in specific occasions.
Anti-theft nut: designed with anti-theft function, such as the internal thread is slotted and equipped with balls and special plastic inner bushing, etc
