    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.

    Operating with less backlash (play) than Precision Acme Lead Screws and Nuts, these provide increased nut life and more reliable movement in automated systems. Also known as single-start and self-locking lead screws and nuts, they have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won’t unexpectedly move when the lead screw is at rest. All components are corrosion resistant for use in harsh environments. To ensure compatibility, select components that have the same thread type, thread size, and number of thread starts.

    Acetal—Acetal nuts have good wear and corrosion resistance.
    Wear-Compensating Spring—Flange nuts with wear-compensating internal O-ring or wear-compensating spring maintain a tight fit even when their threads begin to wear. They resist backlash to maintain accuracy over time, which is important in positioning applications such as 3D printing and robotics.
    Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

    Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start. Operating with less backlash (play) than Metric Precision Acme Lead Screws and Nuts, these lead screws and nuts provide increased nut life and more reliable movement in automated systems. To ensure compatibility, select components that have the same thread size and number of thread starts.

    Acetal—Acetal nuts have good wear and corrosion resistance.
    Wear-Compensating Internal O-Ring—Flange nuts with wear-compensating internal O-ring maintain a tight fit even when their threads begin to wear. They resist backlash to maintain accuracy over time, which is important in positioning applications such as 3D printing and robotics.
    Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

    Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start. Operating with less backlash (play) than Precision Acme Lead Screws and Nuts, these lead screws and nuts provide increased nut life and more reliable movement in automated systems. All components are corrosion resistant for use in harsh environments. To ensure compatibility, select components that have the same thread type, thread size, and number of thread starts.

    Body

    With a plastic seal and closed body, these rivet nuts add threads to sheet metal while keeping out water and dust. Install them in wet environments on surfaces that protect equipment, such as fuse box housings. They help maintain an enclosure’s IP68 rating for protection from water submersion and airborne dust.
    Install these nuts in a drilled or punched round hole using a rivet nut tool. Choose an air- or battery-powered tool for faster installation or to install many different nut sizes. Length is measured from under the flange.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these nuts resist rust and mild chemicals.

    Seal out contaminants and resist torque. These rivet nuts have a PVC foam seal beneath the flange so liquids and gases won't leak between the nut and surrounding material. The ribbed body keeps them from spinning out, even if you frequently tighten or loosen screws.
    Install these nuts in a drilled or punched round hole using a rivet nut tool. Choose an air- or battery-powered tool for faster installation or to install many different nut sizes. Length is measured from under the flange.
    Lightweight Aluminum—At one-third the weight of steel or brass, use these nuts in applications with strict weight limits, such as robotics and aerospace parts. They resist rust almost as well as stainless steel but aren't as strong.

    Body

    Flat sides keep these hex-shaped nuts from spinning out, while a plastic seal and closed body keep out debris and shield screws. Install them in wet environments on surfaces that protect equipment, such as fuse box housings. They help maintain an enclosure’s IP68 rating for protection from water submersion and airborne dust.
    Install these nuts in a drilled or punched round hole using a rivet nut tool. Choose an air- or battery-powered tool for faster installation or to install many different nut sizes. Length is measured from under the flange.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these nuts resist rust and mild chemicals.

    These rivet nuts install with the twist of a screw and seal out moisture. Their narrow legs collapse into a flange that holds the nut in place without crushing your material. The PVC-coated flange prevents water and other liquids from seeping through holes and corroding threads or damaging internal components. Use a power-driven rivet nut tool for fast installation. Also known as jack nuts.
    Zinc-Plated Steel—A step up from plain steel, the plating withstands occasional exposure to moisture.
