Hexagonal Slotted Nuts Features and Installation and Removal MethodsIndustry Solutions

A hexagon-slotted nut is a standard fastener with many uses and can play an essential role in various mechanical equipment and structures. Its unique design has many advantages that can meet the needs of different fields.

Slotted nuts can be classified into different types according to their usage and structural characteristics: standard slotted nuts, high-type slotted nuts, thin-type slotted nuts, locking slotted nuts, etc. These various types of slotted nuts have their characteristics and scope of application, and users must choose according to the specific requirements of reasonable choice.

①, the number of slots:

≤M39: 6 slots

M42~M68: 8 slots

M42~M68: 8 slots ≥M72: 10 slots

②, Cotter pin length for reference only

③, Material:

a) Steel, performance grade: d < 5mm: as per agreement; 5mm ≤ d ≤ 39mm: 6,8,10; d > 39mm: as per agreement. Standard DIN EN ISO 898-2

b) Stainless steel, performance classes: d ≤ 20mm: A2-70; 5mm < d ≤ 39mm: A2-50; d > 39mm: as per agreement. Standard DIN EN ISO 3506-2

c) Non-ferrous metals, performance classes: CuZn = copper-zinc alloy. Standard DIN EN 28839

① With galvanic coating according to DIN EN ISO 4042, it is essential to ensure that nuts with tolerance class 6H do not fall below the zero line. Depending on the required layer thickness, a larger essential dimension than that in the H-position must be selected. A larger essential dimension can impair the stripping strength of the screw-nut connection.

② If strength classes other than those in this standard are required in exceptional cases, e.g., other strength classes, these must be selected by the relevant standards.

③ Deviating from DIN EN ISO 898-2, the minimum hardness 272 HV 30 is sufficient for property classes 8 and 10, even for nuts with a fine thread.

Hexagon Slotted Nuts High Torque Capacity

Hex-slotted nuts are uniquely designed with six corners and slots that provide higher torque capacity, effectively preventing the nut from loosening under vibration or force. Compared to conventional hexagon nuts, hexagon slotted nuts rely on the design of the deep slots to provide a more robust resistance force, making the fastener fixing more robust and reliable.

Hexagon slotted nuts are easy to install and remove

Another feature of hexagon-slotted nuts is their ease of disassembly. Conventional nuts are difficult to disassemble after tightening, mainly when used on equipment that often needs to be adjusted or replaced. If the bolts need to be disassembled frequently, it will be easier to use hexagon-slotted nuts.

Due to its unique design, the hexagon slotted nut is straightforward to install and remove. This type of nut can be easily rotated and secured using a wrench with the appropriate hexagonal jaws. Compared to other kinds of nuts, hexagon-slotted nuts can be installed and removed faster and easier, saving time and human resources and avoiding errors in the application process.

1. Use a slotted wrench to disassemble slotted nuts: Slotted nuts are difficult to disassemble due to their unique structure, which requires specialized tools. Among them, the notched wrench is a more common disassembly tool. The method of use is as follows:

1.1 Choose a suitable slot wrench. To ensure smooth disassembly, the wrench should be selected according to the actual size of the slotted nut.

1.2 Hold the handle of the slot wrench and insert it into the slot of the slotted nut.

1.3 Turn the slotted wrench clockwise or counterclockwise until the slotted nut is removed.

2. Use a slotted screwdriver to disassemble the slotted nut: The slotted screwdriver is also a standard tool for disassembling the slotted nut and is used as follows:

2.1 Select the appropriate slot screwdriver, which should be based on the slot width of the slotted nut to select the screwdriver.

2.2 Slowly insert the slotted screwdriver into the slot of the slotted nut; never use too much force to avoid damaging the internal threads.

2.3 Rotate the slotted screwdriver until the slotted nut is removed.

Hexagon Slotted Nuts Uses and Application Industries

Hexagon-slotted nuts can also be used as anti-loosening nuts. In mechanical equipment and structures, fasteners are easy to lose due to long-term vibration and load, affecting the regular operation of mechanical equipment. The unique design of hexagon slotted nuts gives them high anti-loosening ability, which can effectively prevent the fasteners from loosening and improve the service life and safety of the equipment.

Hexagon-slotted nuts can also be used to adjust the degree of fastener tightness. By tightening or loosening the nut, the tightening strength of the connectors can be adjusted to meet the needs of different working conditions. This is particularly important in the maintenance and commissioning of mechanical equipment and can be easily adjusted and corrected to improve the operational efficiency and performance of the equipment.

Hexagon-slotted nuts are also characterized by easy installation and removal. Due to their unique hexagonal shape, they can be conveniently operated with tools such as wrenches. This makes them more convenient and efficient in compact spaces or where frequent disassembly is required.

As an essential fastener, the hexagon slotted nut is irreplaceable in mechanical equipment and structures. Its unique design and multiple functions of securing, loosening, adjusting, and installing provide convenience to engineers and technicians in various industries. Whether in automobile manufacturing, aerospace, construction, or daily life, hexagon-slotted nuts are indispensable, bringing convenience and safety to our lives and work.

Hexagon-slotted nuts can be used in a variety of high-pressure environments. This is because they provide an extra locking force to keep fasteners strong in these environments. This type of nut also offers good coverage and high corrosion resistance for long-term stability in harsh environments. As a result, hexagon-slotted nuts are often one of the best choices for applications that must withstand heavy loads, high pressures, and varying temperature environments.

1. Machinery Manufacturing: Hexagon slotted nuts are widely used in machinery manufacturing. They can be used to install various equipment and machines and to splice and repair heavy machinery, such as pressure vessels and steel bridges.

2. Aerospace: Hexagon-slotted nuts are also widely used in aerospace equipment. Its superior anti-loosening performance makes it a necessary component of aviation engineering for engine fixing, aircraft decoration, and electronic equipment installation.

3. Automobile manufacturing: Hexagonal slotted nuts are an essential standard component. They can be used in automobile engines, chassis, transmission systems, and body connections to ensure the safety and reliability of the car.

With the advantages of anti-loosening and easy disassembly, hexagon-slotted nuts have many applications in machinery manufacturing, aerospace, automobile manufacturing, and other fields. Understanding its essential functions and uses is necessary for engineering design and maintenance. Hexagon slotted nuts are fasteners that provide higher torque capacity, ease of installation and removal, and suitability for various high-pressure environments. If you need a high-performance fastener for your application, hexagon slotted nuts are the product to choose from—Juxin Fasteners, Email:adelajonly@gmail.com,www.juxinfasteners.com.
