DIFFERENCE BETWEEN BOLT AND SCREW
Bolts and screws are two types of fasteners that are commonly used in construction, manufacturing, and DIY projects. Although they may seem similar, there are some key differences between bolts and screws. In this article, we will discuss the main differences between bolts and screws.
Thread Type
One of the main differences between bolts and screws is their thread type. Bolts have a full thread that runs from the head to the end of the shank. This means that the threads cover the entire length of the bolt. Screws, on the other hand, have a partial thread that only covers a portion of the shank, typically the lower half.
Head Shape
Another key difference between bolts and screws is their head shape. Bolts have a hexagonal head that requires a wrench or socket to tighten or loosen. This type of head provides a more secure grip and is less likely to strip than other types of heads. Screws, on the other hand, have a variety of head shapes, including flat, round, pan, and oval. Some screws also have a recessed head that can be tightened or loosened with a screwdriver.
Application
Bolts and screws are used for different applications. Bolts are typically used in situations where a strong and secure connection is needed. They are commonly used in construction, automotive, and machinery applications. Screws, on the other hand, are used in a wider variety of applications, including woodworking, metalworking, and electronics. They are also commonly used in household applications, such as attaching hinges and door handles.
Length
Bolts are generally longer than screws. This is because bolts are designed to pass through two or more components and be secured with a nut on the other side. Screws, on the other hand, are designed to be screwed directly into a material without the need for a nut. This means that screws are typically shorter than bolts.
Thread Pitch
The thread pitch of bolts and screws is also different. The thread pitch refers to the distance between the threads. Bolts generally have a coarser thread pitch than screws, which means that they are able to provide a more secure grip. Screws, on the other hand, have a finer thread pitch, which allows them to be inserted more easily into materials.
In conclusion, bolts and screws are both important fasteners that are used in a variety of applications. While they may look similar, there are several key differences between them, including their thread type, head shape, application, length, and thread pitch. Understanding these differences can help you choose the right fastener for your specific project or application
