Before diving into nyloc nuts, we need to know about locknuts. So, what is a locknut?
A locknut is a threaded fastener with locking capabilities. It is designed in such a way that it resists loosening under vibration and/or torque.
There are many types of lock nuts. One example is a Nylon-insert lock nut or nyloc nut.
What is a Nyloc Nut?
Nyloc nut gets its name from Nylon-insert lock nut. Because it is a type of friction lock nut with an inserted nylon collar for friction, placed towards the top of the nut.
It is also called a polymer insert lock nut or elastic stop nut. The nylon insert locks the nut against the screw. This happens because of the friction caused by the nut turning against the thread.
It consists of a nylon insert within the head, reducing the inner diameter of the nut. This insert deforms elastically to lock the bolt into place.
A nyloc nut utilises the elastic deformation of the insert to stay in shape against torque or external shock. It can retain its locking abilities up to 121 C (250 F).
Advantages of using Nyloc Nuts
The most important benefit of using nyloc nuts is that they are unaffected by vibrations. This makes them perfect to use as lock nuts. Especially in places that experience more external shocks.
The nylon insert provides an increased grip between the nut and the bolt. As a result, it lasts longer and is harder to unlock.
Due to the placement of the nylon, they can completely lock out moisture. This securely seals the bolt in place.
Where are Nyloc Nuts used?
It is the ideal locking nut in applications where the vibrations can loosen or undo the nut. Nyloc nuts can also be used to seal the bolt thread against water, oil, and other liquids. Some of the applications of nyloc nuts are:
- Computers
- Furniture
- Medical equipment
- Elevators
- Construction
- Vehicles
- Light poles
- Railroad equipment
Precautions
Firstly, before using a nyloc nut, it is important to check the nylon insert for damage. If the insert is damaged, it will affect the locking capability of the nut.
The insert also makes the nut sensitive to temperature and chemicals, as compared to nuts with only metal components. This implies that nyloc nuts work only up to a certain temperature.
It is not advised to reuse nyloc nuts. This is mainly because their efficiency decreases with every use. It is the nylon insert that retains damage over time.
Nyloc nut requires the use of a tool for installation. But the rotation speed must be kept in check as it might overheat and damage the nylon insert.
Summing Up
There are many types of locking nuts and nyloc nuts are one type. They use a nylon insert for their locking mechanism. This insert prevents the nut from loosening.
The nylon restricts its use in applications with high temperatures and certain chemical industries. Although, it provides a seal against liquids and gases.
Nyloc nuts are used widely in various industries for different applications. They generally last longer and are more reliable. Visit www.bhavyaindustries.com to get the best quality nyloc nuts and other products at reasonable prices.
