    Steel Phillips Rounded Head Thread-Cutting Screws

    Image of Product. Front orientation. Tapping Screws. Steel Phillips Rounded Head Thread-Cutting Screws.
    Cut threads in drilled holes as you turn these screws. Because they remove material, they take less effort to install and put less stress on your workpiece than thread-forming screws. The Phillips drive handles enough torque to keep drivers from slipping and the rounded head creates a finished look.
    Length is measured from under the head.
    Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
    Black-Zinc-Plated Steel—The dark finish withstands occasional exposure to moisture while creating a finished look.

    Steel Phillips Flat Head Thread-Cutting Screws

    Image of Product. Front orientation. Tapping Screws. Steel Phillips Flat Head Thread-Cutting Screws.
    Cut threads as you drive these screws, and their beveled head sits neatly inside countersunk holes. They remove material to create threads, so they’re easier to install and put less stress on your workpiece than thread-forming screws. The Phillips drive handles enough torque to keep drivers from slipping.
    Length is measured from the top of the head.
    Black-Oxide Steel—Typically chosen for their appearance, these screws have a dark, matte coating for a finished look. They offer minimal corrosion resistance, so they're best for dry environments.
    Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

    Often used in glass-filled nylon and other tough thermoplastics, these screws create threads where thread-forming screws can’t. They cut away material as they drive to fasten without deforming the hole and have coarse threads for a sure grip. The Phillips drive handles enough torque to keep drivers from slipping and the rounded head creates a finished look. Also known as Type BT and Type 25 screws.
    Length is measured from under the head.
    410 Stainless Steel—Tougher and more wear resistant than other stainless steel screws but less corrosion resistant.
    Round—The sharply angled threads drive into plastic with less force and a lower risk of cracking than other tapping screws. The base of the threads is recessed to bite deep into material and hold tight. You can reuse these screws a few times without stripping the threads. They're comparable to PT screws.

    Drive these corrosion-resistant screws into drilled holes and they cut their own threads. Because they remove material, they take less effort to install and put less stress on your workpiece than thread-forming screws. The Phillips drive handles enough torque to keep drivers from slipping and the rounded head creates a finished look.
    Length is measured from under the head.

    Stainless Steel Phillips Rounded Head Thread-Cutting Screws for Soft Metal

    Image of Product. Front orientation. Tapping Screws. Stainless Steel Phillips Rounded Head Thread-Cutting Screws for Soft Metal.
    A wide slot at the tip cuts threads and clears chips, reducing the effort to drive these screws. They create threads in drilled holes in soft metals, such as brass, and resist rust in damp environments. The Phillips drive handles enough torque to keep drivers from slipping and the rounded head creates a finished look.
    Length is measured from under the head.

    Steel Phillips Flanged Hex Head Thread-Cutting Screws

    The combination drive lets you install screws with a Phillips driver or switch to a nutdriver or socket for more torque. Because these screws remove material, they take less effort to install and put less stress on your workpiece than thread-forming screws. The flanged head spreads the load to prevent crushing thin metal.
    Length is measured from under the flange. Head height includes the flange.
    Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
