JM Hardware® Hex Flange Nut

Flange Nuts have flat and serrated designs designed to act as an integrated, non- spinning washer, eliminating the need for a separate washer. Serrated flange nuts are fabricated with a built in serrated washer that resist loosening due to vibration.

Flange nuts have a washer-like base to distribute pressure over a greater surface area and ensure the fastener stay tight. They are commonly used in manufacturing assembly lines where operations are speeded by using a single fastener instead of a nut and washer.
