    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.
    Corrosion-Resistant Stainless Steel
    18-8 Stainless Steel—The choice for wet and outdoor environments, these nuts resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
    Highly-Corrosion-Resistant 316 Stainless Steel—The most corrosion-resistant stainless steel coupling nuts we offer, these hold up in just about any environment. They won't degrade from exposure to weather, salt water, and most chemicals.

    Stack male-threaded components and create a clean, flush connection between them. To securely tighten standoffs, grip the flat sides of the hex body with a wrench.
    Corrosion-Resistant 18-8 Stainless Steel—The choice for wet and outdoor environments, these standoffs resist rusting. They're strong enough for most jobs, but won't withstand stress as well as steel.
    Zinc-Plated Carbon Steel—Best for dry environments since moisture will cause these standoffs to rust.
    Lightweight Aluminum—One-third the weight of steel, these standoffs are commonly used in applications with weight limitations. They resist rust as well as stainless steel, but they're not as strong.

    Lightweight, nonconductive, and naturally rust-resistant. Screw these standoffs onto male-threaded panels and equipment covers to separate, position and connect other male components.
    Nylon 6/6—Lightweight and stand up to daily wear and tear. Nylon swells and weakens when exposed to moisture, so these standoffs are best for dry environments.

    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.
