    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.
    Zinc-Plated Brass—Typically chosen for their warm, polished look, these standoffs are suitable for outdoor, low-stress applications. The zinc plating resists corrosion, but brass is softer than other metals, so these standoffs may deform under high stress.

    Threaded Rods

    Image of Product. Front orientation. Threaded Rods. Threaded Rods.
    Anchor, connect, or hang components in a wide variety of applications, from mounting I-beams to suspending light fixtures.
    Low-Strength Steel
    With a tensile strength of 50,000 psi or 60,000 psi, these rods are often used to suspend light fixtures, cable trays, and conduit from ceilings. They're about half the strength of medium-strength steel rods. To avoid stripped threads during installation, make sure your nuts are also low-strength steel.
    Zinc-Plated Steel—The most common choice for areas with occasional exposure to moisture.
    Steel—Best for dry environments since moisture will cause these rods to rust.

    Stainless Steel
    More corrosion resistant than steel rods and comparable in strength to low-strength steel.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these rods resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
    Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these rods won't degrade when exposed to harsh weather, salt water, and most chemicals.

    Lightweight, nonconductive, and naturally rust-resistant. Screw these standoffs onto panels and equipment covers to separate, position and connect components. To securely tighten standoffs, grip the flat sides of the hex body with a wrench.
    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.
