    Made of alloy steel, these screws are the standard for high-strength fastening. Use them in high-load applications such as dies, presses, and heavy equipment. The deep, six-point socket keeps the hex key from slipping out and damaging the drive.
    Length is measured from under the head.
    Black-Oxide Alloy Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

    Steel Hex-Drive Flat Head Screws

    Image of Product. Front orientation. Flat Head Screws. Steel Hex-Drive Flat Head Screws.
    Our strongest hex-drive flat head screws. They're made of alloy steel, so they have nearly twice the tensile strength of other screws. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver without slipping and stripping the drive.
    Length is measured from the top of the head.
    Black-Oxide Alloy Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.
    Zinc-Plated Alloy Steel—A common choice for areas with occasional exposure to moisture.
    Standard Profile—Standard-profile heads are the most common choice for flat head screws.

    Stainless Steel Hex-Drive Flat Head Screws

    Image of Product. Front orientation. Flat Head Screws. Stainless Steel Hex-Drive Flat Head Screws.
    The most corrosion-resistant hex-drive flat head screws we offer. Made of stainless steel, they won't rust or corrode when exposed to moisture and chemicals, but they're not as strong as alloy steel. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver without slipping and stripping the drive.
    Length is measured from the top of 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.
    Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these screws won't degrade when exposed to harsh weather, salt water, and most chemicals.
    Standard Profile—Standard-profile heads are the most common choice for flat head screws.

    Fully Threaded

    Secure parts without adding much weight. These plastic screws are also nonconductive and resist chemicals and oil. The deep, six-point socket keeps hex keys from slipping out and damaging the drive.
    Length is measured from under the head.
    Nylon—The most common choice for a plastic screw, these are good for general purpose fastening. They are slippery and abrasion resistant, so they thread on smoothly and stand up to daily wear and tear.
