The three basic types of fasteners are screws, bolts, and nails. These fasteners are commonly used in construction, woodworking, and various other applications. Here’s a brief overview of each type:

Screws: Screws are threaded fasteners that require a rotational motion to drive them into a material. They have a pointed end and a threaded shaft. Screws are often used to hold two or more objects together by creating a secure connection.

Bolts: Bolts are similar to screws but differ in their usage. Unlike screws, bolts do not have a pointed end and are typically used with a nut to create a secure connection. Bolts have a threaded shaft and require a wrench or spanner to tighten them. They are often used in applications that require higher load-bearing capacity and where disassembly may be necessary.

Nails: Nails are simple, cylindrical fasteners with a pointed end and a head. They are typically made of metal and are used to secure objects by being driven into a material, usually wood or other soft materials.

These three basic types of fasteners each have their specific applications and provide different levels of strength, durability, and ease of use. It’s important to choose the right type and size of fastener based on the material and purpose of your project to ensure a secure and reliable connection.
