A square nut
is a type of fastener with a square-shaped hole in the center. It is commonly used in conjunction with a threaded bolt or screw to secure two or more objects together. The square shape of the nut prevents it from rotating when tightened, providing a more secure connection compared to regular nuts, which can easily loosen over time.
Square nuts are often used in construction, woodworking, and various mechanical applications. They can be made from different materials such as steel, stainless steel, brass, or nylon, depending on the specific requirements of the project. Square nuts are available in various sizes and thread types to match the corresponding bolts or screws.
To use a square nut, you typically insert it into a pre-drilled or pre-tapped hole and thread a bolt or screw through it. As you tighten the bolt or screw, the square nut locks into place, preventing it from spinning and ensuring a tight connection between the objects being fastened.
Overall, square nuts provide a reliable and durable fastening solution, particularly in applications where vibration or movement could cause traditional nuts to come loose.
