Square Nuts, #10-24, Zinc Plated Steel 10 Pack, Prime-Line, Mfr#: 9192524

Square nuts are similar in function to hex nuts, but are 4-sided instead of 6-sided. This shape increases the contact surface, which can help to prevent loosening in certain applications. They are sometimes used in tight spaces since the square shape allows them to be tightened using pliers. Another application is use in metal channels.
