- Design and Function: Its primary advantage is a large contact surface that provides resistance against rotation. This makes it particularly effective when used in conjunction with slotted channels or T-slots, where the flat sides prevent the nut from turning as the bolt is tightened from above.
- Historical and Modern Use: It is one of the oldest nut designs. While largely replaced by the more versatile hex nut in general applications, the square nut remains essential in specific niches. It is the standard fastener for use in T-slotted structural framing, workbenches, certain types of clamps, and some traditional woodworking or blacksmithing.
- Standardization: Common standards include ANSI B18.2.2 for imperial sizes. Its design is straightforward, offering a practical and robust, if less space-efficient, fastening solution for its intended applications.
