    Slotted Drive

    These screws mount flush against the outer panel's surface for low-clearance applications. Install in soft material such as aluminum and low-carbon steel with an arbor press or similar pressure tool. Screws become a part of the panel when installed, so they won't fall out and get lost. They're often used with surface mount nuts.

The screw is held to the outer panel by a retainer. Rivets not included. Install with 3/32" rivets in steel and 1/8" rivets in plastic. Length is measured from under the screw head.
    Zinc-Plated Steel—Zinc-plated steel nuts and screws are corrosion resistant in wet environments. An installation tool (sold separately) is required to install the retainer.
    Acetal—Acetal nuts and screws are chemical resistant and lightweight.
