    Flange Nuts

    Image of Product. Front orientation. Flange Nuts. Flange Nuts.
    No need for a separate washer—these nuts have a plain flange that distributes pressure evenly for a wide variety of fastening applications. They are ideal for securing screws in oversized or irregularly shaped holes since the flange covers a larger area than standard nuts. Also known as collar nuts.
    Fiberglass
    Fiberglass—With the best strength-to-weight ratio of all our flange nuts, these hold up in high-stress applications without adding weight to your assembly. They also resist acids, solvents, oil, and salt water.
