    Steel Phillips Hex Head Screws

    No wrench, no worries. If there isn't enough room to turn these screws with a wrench, slip a screwdriver into their Phillips drive. When using a wrench or socket, the head's six flat sides prevent slipping and rounding off the drive.
    Length is measured from under the head.
    High-Strength Fastener—Commonly used to fasten components in valves, pumps, motors, and other high-stress applications. These screws have a tensile strength of 125,000 to 160,000 psi.
    Cadmium-Plated Steel—The plating reduces friction between the screw and your mounting surface to prevent sticking when you tighten or loosen screws. It also creates a barrier against rust.

    Threaded

    Secure rotating parts subjected to vibration, such as the wheels on carts and hand trucks. A cotter pin (not included) slides through the hole in the shank of these screws to keep nuts from loosening. They hold stronger than screws with threadlocker and lockwashers, but they aren’t recommended for high-vibration applications because prolonged stress can shear the pin. The head's six flat sides keep wrenches and sockets from slipping and rounding off the drive.
    Length is measured from under the head.
    Medium-Strength Fastener—Your go-to screws for fastening most machinery and equipment. They have tensile strengths from 90,000 to 120,000 psi.
    Cadmium-Plated Steel—The plating reduces friction between the screw and your mounting surface to prevent sticking when you tighten or loosen screws. It also creates a barrier against rust.

    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.
    Cadmium-Plated Alloy Steel—The plating reduces friction between the screw and your mounting surface to prevent sticking when you tighten or loosen them. It also creates a barrier against rust.
    Military Specification—Manufactured and tested to meet strict U.S. military standards for material and construction.

    Steel Cup-Tip Set Screws

    Image of Product. Front orientation. Set Screws. Steel Cup-Tip Set Screws.
    Made of alloy steel, these screws are strong enough to hold components without wearing down. The tip has thin edges that dig into surfaces for a secure hold. They often lock gears, pulleys, and other transmission components onto shafts.
    Cadmium-Plated Alloy Steel—The plating reduces friction between the screw and your mounting surface to prevent sticking when tightening and loosening. It also creates a barrier against rust.
    Military Specification—These screws are manufactured and tested to strict U.S. military standards for material and construction.

    Mil. Spec. Steel Hex-Drive Flat Head Screws

    Image of Product. Front orientation. Flat Head Screws. Mil. Spec. Steel Hex-Drive Flat Head Screws.
    Manufactured and tested to meet strict U.S. military standards for material and construction. These screws are 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.
    Cadmium-Plated Alloy Steel—The plating reduces friction between the screw and your mounting surface to prevent sticking when you tighten or loosen them. It also creates a barrier against rust.
    Standard Profile—Standard-profile heads are the most common choice for flat head screws.
