    Coupling Nuts

    Image of Product. Front orientation. Coupling Nuts. Coupling Nuts.
    Also known as extension nuts, these are commonly used to connect lengths of threaded rod and join threaded parts.
    Low-Strength Steel
    Rated Grade 2 or lower, these are about half as strong as medium-strength steel coupling nuts. Use them with threaded rods that have a comparable strength rating to avoid stripping threads during installation.
    Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.
    Black-Oxide Steel—A dark, matte coating creates a finished look. Nuts offer minimal corrosion resistance, so they're best for dry environments.

    Brass
    Brass—With a warm, polished look, these nuts are often chosen for their appearance. Similar to 18-8 stainless steel, brass is corrosion resistant enough to stand up to wet environments. It is also softer than other metals, so it's easier to thread together.

    Fully

    Threaded

    The smallest standoffs we offer. These press into unthreaded holes to create permanent connections without welding, tapping, or installing extra hardware. The raised splines prevent rotation, and a recessed head clinches material for a strong hold. A through hole allows installation from one side, making them ideal for compact electronics like laptops and handheld devices.
    Wear-Resistant 400 Series Stainless Steel—These standoffs can grind against metal surfaces without denting or scratching. More corrosion resistant than steel.

    High-Profile Hex Nuts

    Image of Product. Front orientation. Hex Nuts. High-Profile Hex Nuts.
    Slightly taller than standard-profile hex nuts, these have a larger gripping area so your wrench or socket won't slip off as you tighten them. They're often used in vehicles and machinery where fasteners can be difficult to reach.
    Low-Strength Steel
    Rated Grade 2, Class 6, or lower, these nuts are about half as strong as medium-strength nuts. They are suitable for light duty fastening applications, such as securing access panels. Use them with screws that have a similar strength rating to avoid stripping threads during installation.
    Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.
