Slotted nuts, especially hexagonal slotted nuts, are fasteners with special designs. The following is a detailed introduction to slotted nuts:
1, Definition and Characteristics
Slotted nuts are mainly designed to be machined above hexagonal nuts, allowing them to be used in conjunction with threaded bolts with holes and split pins to prevent relative rotation between the bolt and nut. Its characteristics include:
1. Superior anti loosening performance: By inserting the split pin, the nut can be effectively prevented from loosening in vibration or impact environments, improving the reliability of the connection.
2. Complex external structure: Due to the need to machine grooves above the nut, its external structure is relatively complex, and the degree of deformation during molding is large, so special attention needs to be paid during the production process.
2, Type and specifications
1. Type: Slotted nuts mainly refer to hexagonal slotted nuts, but there may also be other types of slotted nuts.
2. Specifications: There are various specifications for slotted nuts, with common diameters ranging from M2 to M100. Specific specifications can be selected according to actual needs. In addition, slotted nuts are divided into coarse and fine teeth, as well as different product grades (such as A grade, B grade, etc.).
3, Materials and Applications
1. Material: Slotted nuts can be made of various materials, such as stainless steel, quick cut steel, stainless iron, copper, aluminum, etc. Slotted nuts made of different materials are suitable for different usage environments. For example, stainless steel slotted nuts have good corrosion resistance and are suitable for humid or corrosive environments.
2. Application: Slotted nuts are widely used in applications that require vibration or impact, such as vehicles, mechanical equipment, building structures, and other fields. In the field of vehicles, slotted nuts are commonly used to secure the front and rear axles of vehicles, ensuring a stable connection between the frame and tires.
4, Assembly and use
1. Assembly method: When assembling slotted nuts, it is necessary to first thread the threaded bolt with holes through the connecting piece, and then tighten the slotted nut onto the bolt. Next, insert the split pin into the slot of the slotted nut and pass it through the hole of the screw to secure the slotted nut.
2. Precautions for use:
When choosing slotted nuts, appropriate specifications and materials should be selected according to actual needs.
During the assembly process, it should be ensured that the diameter of the split pin matches the groove width and depth of the slotted nut to ensure proper fixation.
During use, the fastening of the connecting parts should be checked regularly. If looseness is found, it should be tightened or damaged slotted nuts should be replaced in a timely manner.
5, Standards and specifications
The production and use of slotted nuts usually follow certain standards and specifications. For example, in China, the use of slotted nuts is common in standards such as GB6178-6181. In addition, there are corresponding standards and specifications internationally that regulate slotted nuts.
Overall, slotted nuts are a type of fastener with superior anti loosening performance, widely used in various situations that require vibration or impact resistance. When selecting and using slotted nuts, appropriate specifications and materials should be chosen according to actual needs, and corresponding standards and specifications should be followed for assembly and use.
