The rectangular bead
The connection of such nuts with a wrench is non-slip, and due to the large seating surface they have, they have high friction; Therefore, by using these types of screws, you will have more resistant connections.
Hexagonal beads
Hexagonal nuts are more likely to loosen compared to square nuts; But due to having more ears, the amount of surface wear of these beads is less than square beads. Among the other advantages of these nuts compared to the square nuts, it can be pointed out that for each rotation of these nuts by the operator, an angle of 60 degrees is needed, while in the case of square nuts, this angle is 90 degrees.
Car nut
Machine nuts are produced and supplied in square and hexagonal types. These beads are the smallest types of square and hexagonal beads.
Winged vertebra
This category of beads is also called rooster beads. These nuts are designed to be opened and closed by hand, without using any tools. These beads are used to adjust the height of tables and camera bases, etc.
Load bead
Closed beads that have a round and dome-shaped surface at the end; They are attached to the ends of threaded rods or screws to prevent them from hitting other objects and body parts. These nuts are also produced in the form of long closed nuts (Acorn nut) which cover more thread surface.
Groove bead
On one side of the grooved nuts, there are a number of grooves for the pin to pass through. These pins are more resistant to vibration and impact. Installing and removing this type of nut is easier than other locking nuts.
Nylon ring
On one side of the threads of this nut, a nylon ring is installed, which is smaller than the size of the screw; because it acts like glue and makes the movement of the screw more difficult; As a result, you will have a more resistant connection with these nuts. Due to the presence of nylon polymers in the structure of the beads, it is not possible to use them at high temperatures.
