    Self-Aligning Flange Nuts

    Clamp workpieces that aren't perfectly parallel to the mounting surface. Also known as spherical collar nuts, these have a curved base and washer that fit snugly together and swivel to compensate for slight misalignment. Nuts distribute pressure evenly as they tighten to prevent damage to the part.
    Height includes the nut and the washer.

    Black-Oxide Steel—Typically chosen for their appearance, these nuts have a dark, matte coating that creates a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

    Fasten together unaligned parts and keep screws in place. The threaded hole within these press-fit nuts shifts up to .01" in any direction, so you can fasten together thin panels with off-center holes. The irregularly shaped threads tightly grip screws to prevent them from loosening or backing out under vibration.

    Help screws pass through perfectly every time. These nuts float inside a rectangular retainer that shifts and tilts to compensate for misalignment. A pilot tip locates the hole, and the retainer holds the nut in place during welding.
    Steel with Steel Retainer—Best for dry environments since moisture will create rust. Weld them to steel surfaces.
    Zinc-Plated Steel with Steel Retainer—A step up from a plain steel nut, the zinc plating on these nuts withstands occasional exposure to moisture. Weld them to uncoated steel surfaces.
    Zinc-Plated Steel with Aluminum Retainer—Both the nut and retainer can withstand occasional exposure to moisture. Weld them to aluminum surfaces.
    18-8 Stainless Steel with Stainless Steel Retainer—Suitable for outdoor use, both the nut and its retainer resist rust from water and mild chemicals. Weld them to stainless steel surfaces.

    Self-Aligning Key-Locking Threaded Inserts for Soft Metal

    Align threads with off-center parts. These inserts have floating threads that shift slightly so you can insert screws at a slight angle as you fasten two parts together. They're comparable to Keensert inserts.
    To install, drill and tap a hole in your material. Then, thread the insert onto the installation tool and screw it into the hole. Place the tool over the keys and hit it with a hammer to drive them in.
    Standard Wall—Stronger than thin-wall inserts, these are your go-to choice for threading most holes.
    Thin Wall—Use these inserts near the edge of workpieces or wherever you only have space for a small hole. They're also lighter than standard and extra-thick wall inserts for applications with strict weight limitations.
    High-Strength Cadmium-Plated Alloy Steel—These inserts have the strength to stand up to high-pressure applications and a plating that helps screws thread in smoothly.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.
