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.


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.Lag screws for wood


Spring lock washer. This type of washer also provides efficient vibration resistance. When you want to purchase the right spring lock washer, 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 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 screwheads).

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.
