      About Square Nuts

      Square Nuts are a type of fastener commonly used in industrial and construction applications. Square Nuts are typically threaded and designed to be secured to a bolt, threaded rod, or other fasteners to create a secure connection between two pieces of material.

      Types of Square Nuts

      Square Nuts come in several sizes and shapes including square nuts with flanges, and hexagonal square nuts. Depending on the application, certain types of Square Nuts may be more suitable than others due to their different dimensions, threading patterns, or material compositions.

      How Square Nuts are Made

      Square Nuts are typically manufactured from steel alloys that can withstand high levels of stress and strain while also being corrosion resistant. Depending on the application they may be heat treated for additional strength or plated with zinc for added protection against rust.

      Industries that use Square Nuts

      Square Nuts are often used in automotive repair shops when replacing brakes or shock absorbers. They're also frequently used by construction professionals when installing decking boards or railing systems. Finally, they’re commonly used by electricians when mounting electrical boxes onto walls using square threaded rods and nuts.
