Lock Nut

What is a nut ?

A nut is a type of fastener with a threaded inner diameter. It is used to join two or more metal or wood parts. Nuts are usually made of metal, but they can also be made of plastic or other materials. Nuts are usually tightened by hand or with a wrench. In some cases, nuts may be welded or glued to their mating surfaces.

What are nuts used for?

Nuts are most commonly used to secure bolts or screws. They can also be used to connect other types of fasteners, such as washers. Nuts can also be used on their own, without bolts or screws. In this case, they are often used to plug the ends of threaded rods.

Where and when are nuts used?

Nuts are used in a wide variety of applications, both industrial and domestic. They are found in machinery, on mechanical parts, furniture, and even toys. 

How do I use a nut?

Using a nut is a relatively simple process, but there are a few things to watch out for. First, make sure the nut you use is the right size for the bolt or screw you are attaching it to. Next, align the nut with the bolt or screw so that the threads line up.

What are the different types of nuts?

At 123Bearing, we only sell lock nuts for clamping sleeves. They can be SKF, INA, RHP, SPIETH or generic 123Bearing brand nuts for clamping sleeves.

Apart from this type of nut, there are many other categories of which here is a non-exhaustive list:

  • Hexagonal nut : The hexagonal nut is the most common type of nut. It is used in many applications, including machinery and furniture. It is usually tightened by hand or with a wrench.
  • Square Nut : The square nut is similar to the hex nut, but has a square shape. It is used in the same applications as the hex nut.
  • Slotted Nut : The slotted nut has a slot on top that allows it to be tightened or loosened with a screwdriver. It is often used in applications where a wrench cannot be used.
  • Locknut : A locknut is a locking nut with an integral washer. The washer is designed to rotate freely until the nut is tightened, at which time it locks the nut in place. This prevents the nut from loosening due to vibration or other forces. Locknuts are often used in applications where reliability and safety are paramount, such as in aerospace and automotive applications.
  • Wing Nut : A wing nut is a type of fastener with a threaded hole and two wings that protrude from the sides.
  • Nylstop Nut : A nylstop nut, also known as a lock nut, is a type of lock nut with a nylon insert. The insert locks the nut in place and prevents it from loosening. The lock nut is often used in applications where reliability and safety are paramount, such as aerospace and automotive.
  • T-Nut : This part has a unique shape that allows it to be inserted into a T-slot.

There are many brands that manufacture nuts, such as: SKF, INA, RHP, which are sold on our site.

How to choose the right nut?

When choosing a nut, there are several things to keep in mind. First, consider the size of the bolt or screw you are using, as well as the inside diameter of your nut. Next, consider the material the nut will be made of. You also need to pay attention to the thread direction of the corresponding screw (left-handed or right-handed thread).
