    Stainless Steel Button Head Torx Screws

    Image of Product. Front orientation. Rounded Head Screws. Stainless Steel Button Head Torx Screws.
    Our most corrosion-resistant button head Torx screws. The button head looks similar to a pan head, but it's lower and more compact, taking up less space. With a deep six-lobe opening, the Torx drive prevents your driver from slipping and stripping the drive. Also known as star drives, they withstand more torque than slotted, Phillips, and hex drives.
    Length is measured from under the head.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don't hold up to the harsh chemicals that 316 stainless steel can.

    The most commonly used hex nuts, these are suitable for fastening most machinery and equipment.
    Low-Strength Steel
    Rated Grade 2, Class 6, or lower, these nuts are about half as strong as medium-strength nuts. They are suitable for light duty fastening applications, such as securing access panels. Use them with screws that have a similar strength rating to avoid stripping threads during installation.
    Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.
