Nuts and bolts come in a range of shapes and sizes, but of the variety of different types available, square nuts are among the most popular because of their efficiency and adaptability. Due to their wide, four-sided shape, square nuts offer greater surface contact and are resistant to loosening over time. Square nuts are often used in tandem with flat wasters to decrease the chances of damage and to strengthen the hold of fastening solutions.
