Types of Locking Washers and Their Uses

Posted on by

What is Lock Washer?

The locking washers can be made of metal or non-metal materials. The purpose in using them is to keep nuts and bolts from vibrating or friction loose. They are many different shapes and sizes, but they all try to achieve the same goal. When properly applied, lock washers provide a shabby, basic way to keep threaded fasteners steady over a long period of time.

 

Washer dimensions can come in either imperial or metric units. If you do not have a specific size most manufacturers will be able to custom build a washer to fit your application. Washers can follow ANSI, SAE, USS, and JIS sizes as well.

 

Below, there is a list of split lock, sealing, internal tooth, external tooth, flat, and flat retaining. And I will tell you what each one is and their use.

 

  1. Split Lock – Split locks are also called helical spring lock washers. These are made out of a spring coil that cut or split. This makes it so the two ends of the coil forced outward to the mating surface. So when the washer is fastened each end of the coil will bite into the surface of the head of the screw and to the surface to which you are fastening too.

 

  1. Sealing – Sealing washers use a form of a silicone rubber that is bonded to the steel of the washer. These are made to be used with screws, bolts, and nuts. They are a simple solution to any sealing needs. They have a seal on the bottom of the washer that seals the surface of the washer face, and a seal at the top that encases the shank and under the head of the fastener making a complete seal from top to bottom.

 

  1. Internal Tooth – Internal tooth have teeth on the inner dimension of the washer and the outside of the washer is smooth. They are made for fasteners who have a smaller head. When the head is fastened into the hole the internal teeth will help grab the surface, while at the same time resisting against the force of the washer being compressed.

 

  1. External Tooth – External tooth have teeth on the outer dimension of the washer so that they can actually bite into the surface that it is put on, and the inside is still a cylindrical hole. They are designed for fasteners who have a bigger head. When the head is fastened into the hole the external teeth will help grab the surface, while at the same time resisting against the force of the washer being compressed.

 

  1. Flat – Flat washers are used for basic applications, where the hole is cot directly in the center of the washer. Standard or metric, it does not matter they can accommodate all shapes and sizes.

 

  1. Flat Retaining – These have multiple holes in them so that you can screw or bolt down the washer, and the second hole would be for running your wire to the screw or bolt.

Nuts and Washers – Choosing the Right Type for Your Project

Posted on by

Even the smallest tools and supplies play a huge role in the construction industry. Nuts and washers, for instance, are two small yet very important parts. These are forms of fastener bolts and function by securing the screws in place. Machines, furniture pieces, and other structures frequently exposed to vibrations need these fasteners. Without nuts and washers, the screws can come off and the machine will break apart. This can lead to grave damage to properties and even serious injuries.

This article will discuss the features of nuts and washers and the available types. The following information will be helpful when you are planning to start a construction project that requires screws.

Nuts are oftentimes hexagonal in shape. Hex nuts are the most common types and are used in many general-purpose products. This fastener has a threaded hole in the center. Washers, on the other hand, are simpler types of fasteners. They are usually flat and are available in different shapes and sizes. Similar to nuts, they function by fastening screws and acting as spacers. Steel and plastic washers are the most used types. Steel types help prevent deterioration of two joint metal objects due to electrical contact. Plastic washers are common in valves and faucets.

Since construction projects require the exact types of nuts and washers, you need to choose the right items. The following are some specific types of nuts and washers and their uses.

Nuts

Locknuts. This type is best suited for items that are prone to vibration. They provide resistance to the force of vibrations. They also come in different styles but most of them serve the same purpose.

Wing nuts. This nut type comes with two “wings.” These features make it easier to adjust even with the use of bare hands. This type is ideal for construction projects that need frequent tightening or loosening.

Square nuts. This type usually has a larger surface than hex nuts. This feature makes it easier to grip using wrenches. In some cases, workers weld square nuts to machineries.

Slotted nuts. People also call these castle nuts because of its resemblance to a castle tower. This is also an efficient tool in projects where vibration may take toll on the efficiency of the material. It prevents movement when you fit a pin through the slots on the nut and through the hole in the bolt.

Types of Lock Washers

Spring lock washer. This type of washer also provides efficient vibration resistance. When you want to purchase the right lock washers, you have to consider the size that you need. You have to know the minimum thickness, the inside and outside diameters.

Spherical washer. It has a male and female part. Their sections fit together and are the ideal type for dealing with misalignments.

Tooth lock washer. This type lock washer comes in different teeth types namely, internal (for a cleaner appearance), external (for best locking), internal-external (for electrical grounding), and countersunk external (for round screw heads).

Nuts and washers are usually available in your construction supply store. You can also get these materials online along with other supplies such as beam and column anchors, and concrete inserts. Search for a reliable supplier to get the best materials.
