Introduction
Screws are widely used in a variety of daily applications. From cars to robots, screws are used to fasten things together, attach accessories and even aid in the repair and creation of gears. With so many uses, it is important to identify the different types and models of screws in order to choose the best one for any specific project.
Common Types of Screws
The most common types of screws are flathead (also known as slotted), Phillips head, Robertson, and hex head screws. Each type has its own special shape, drive system, and application. Depending on the application, some screws may be better suited than other types.
Flathead (or Slotted) Screws
Flathead (or slotted) screws are the most popular type of screws used in everyday life. They are used in a variety of applications such as furniture, toys, appliances, and machinery. The flathead screw has an asymmetrical flat head and a tapered tip that fits into a slot in the head of the screw. A slotted drive system is used to remove or attach most flathead screws without the need of a magnetic screwdriver.
Phillips Head Screws
Phillips head screws are some of the most widely used screws in the world. They are commonly found in furniture, appliances, office equipment, and computer systems. This type of screw has a cross-shaped indentation with a slightly rounded edge in the head of the screw that matches with the shape of a Phillips screwdriver. Unlike slotted screws, Phillips screws can be tightened or loosened with a Phillips screwdriver.
Robertson Screws
Robertson screws are also commonly used in everyday life. They are designed to provide a good balance between strength and grip in hard materials such as wood, particle board, and plastics. They have a square indentation in the head of the screw that matches the shape of a Robertson square drive bit. The square head allows for a quick connection and removal of the screw without slipping.
Hex Head Screws
Hex head screws are one of the most popular types of screws used in heavy-duty applications such as automotive and construction projects. They have a hexagonal shape in the head of the screw which allows for a secure connection to the fastener. Hex head screws are commonly used to attach large structures, secure engines, and fasten heavy machinery.
Conclusion
Knowing and understanding the different types and models of screws available is an important part of any project. With the right information and the proper tools, you can easily choose the screw that best suits your need. From slotted screws to hex head screws, there is a perfect screw for nearly any job.
