Square nuts from Agri Supply have several advantages over hex nuts. Square machine nuts do not become rounded off as easily with repeated usages, and square head nuts are also easier to get a tool on when you can't see the nut head. Square machine screw nuts tend to have more surface area than hex nuts and therefore are more resistant to loosening. Nut fasteners from Agri Supply are part of the more than 26,000 items we offer for farm, shop, home and garden.

Square nuts are often preferred for authentic restoration pieces. Square machine nuts were used in machines before hex nuts were invented.

Square nuts are an older style of nut head than hex nuts, but Agri Supply still carries what you need. We have square machine nuts in bags of 10 so you can have plenty on hand. Machine screw nuts are smaller so they fit on the generally smaller machine screws. Square head nuts tend to have greater surface area in contact with the bolt or screw and as such provide more resistance to loosening or tightening.

Square nuts are sometimes preferred because they are less likely to become rounded off than hex nuts. With machine nuts, square nuts are also handy because they are easier to get a tool on when you can't see the nut head. Machine screw nuts are another way we are committed to having something for everyone, from the smallest nut fasteners to major pieces of equipment. Square head nuts are often used with flat washers, which we also carry for your convenience.
