    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.
    Highly Corrosion-Resistant Black-Oxide 316 Stainless Steel—Combines a finished appearance with the rust resistance of 316 stainless steel. Even if the coating wears off, these screws will hold up in just about any environment, including salt water and most chemicals.
    Standard Profile—Standard-profile heads are the most common choice for flat head screws.
    Undercut Profile—About a third thinner than standard heads, the undercut profile fits into shallow holes in thin material. The thin head also has more threading on the shaft, so they're often used to keep short screws from coming loose.

    Stainless Steel Phillips Flat Head Screws

    Image of Product. Front orientation. Flat Head Screws. Stainless Steel Phillips Flat Head Screws.
    These screws are made of stainless steel, so they won't rust or corrode when exposed to moisture and chemicals. The Phillips drive has a cross-shaped opening in which a driver fits snugly for easy alignment. With four contact points, they withstand more torque than slotted drives, but drivers slip when you apply too much force.
    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.
    Black-Oxide 18-8 Stainless Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They won't rust in wet and outdoor environments, but they don't hold up to the harsh chemicals that 316 stainless steel can.
    Standard Profile—Standard-profile heads are the most common choice for flat head screws.
    Undercut Profile—About a third thinner than standard heads, the undercut profile fits into shallow holes in thin material. The thin head also has more threading on the shaft, so they're often used to keep short screws from coming loose.

    Mil. Spec. Stainless Steel Phillips Flat Head Screws

    Image of Product. Front orientation. Flat Head Screws. Mil. Spec. Stainless Steel Phillips Flat Head Screws.
    Manufactured and tested to meet strict U.S. military specifications for material and construction. These screws are made of stainless steel, so they won't rust or corrode when exposed to moisture and chemicals. The Phillips drive has a cross-shaped opening in which a driver fits snugly for easy alignment. With four contact points, they withstand more torque than slotted drives, but drivers slip when you apply too much force.
    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.
    Black-Oxide 18-8 Stainless Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They won't rust in wet and outdoor environments, but they don't hold up to the harsh chemicals that 316 stainless steel can.
    Standard Profile—Standard-profile heads are the most common choice for flat head screws.

    Steel Phillips Flat Head Screws

    One of the most common drive styles. Phillips drives have a cross-shaped opening in which a driver fits snugly for easy alignment. With four contact points, they withstand more torque than slotted drives, but drivers slip when you apply too much force.
    Length is measured from the top of the head.
    Zinc-Plated 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.

    Sealing Stainless Steel Phillips Flat Head Screws

    Keep out dust and contaminants while locking in air and fluid. These screws have a rubber O-ring under the head that compresses to form a tight seal as you tighten them. Made of stainless steel, they won't rust or corrode when exposed to moisture and chemicals. The Phillips drive has a cross-shaped opening in which a driver fits snugly for easy alignment. With four contact points, they withstand more torque than slotted drives, but drivers slip when you apply too much force.
    These screws are reusable as long as the rubber O-ring is intact and undamaged. 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.
    Buna-N O-Ring—These seals won't swell or soften when they touch oil, grease, or fuel. However, they will break down if exposed to synthetic lubricants.
    Silicone Rubber O-Ring—Withstand a wider range of temperatures than Buna-N and Viton® seals without becoming brittle. However, these seals degrade when exposed to oil, grease, and fuel.
    Standard Profile—Standard-profile heads are the most common choice for flat head screws.
    Undercut Profile—About a third thinner than standard heads, the undercut profile fits into shallow holes in thin material. The thin head also has more threading on the shaft, so they're often used to keep short screws from coming loose.

    Plastic Slotted Flat Head Screws

    Image of Product. Front orientation. Flat Head Screws. Plastic Slotted Flat Head Screws.
    These plastic screws are lightweight, nonconductive, and naturally resistant to rust. Use them to attach panels and covers to electronics and automated equipment. With only two contact points, the slotted drive is the most basic drive style. The slot can't withstand much torque, so it's best to hand-tighten them instead of using power tools.
    Length is measured from the top of the head.
    Nylon—The most common plastic flat head screws, these are good for general purpose fastening. They are slippery and abrasion resistant, so they thread in smoothly and stand up to daily wear and tear. Nylon will swell and weaken when exposed to moisture, so these screws are best for dry environments.
    Standard Profile—Standard-profile heads are the most common choice for flat head screws.

    Mil. Spec. Steel Phillips Flat Head Screws

    Image of Product. Front orientation. Flat Head Screws. Mil. Spec. Steel Phillips Flat Head Screws.
    Manufactured and tested to meet strict U.S. military specifications for material and construction. Phillips drives have a cross-shaped opening in which a driver fits snugly for easy alignment. With four contact points, they withstand more torque than slotted drives, but drivers slip when you apply too much force.
    Length is measured from the top of the head.
    Cadmium-Plated 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.

    Stainless Steel Slotted Flat Head Screws

    Image of Product. Front orientation. Flat Head Screws. Stainless Steel Slotted Flat Head Screws.
    The most corrosion-resistant slotted flat head screws we offer. Made of stainless steel, they won't rust or corrode when exposed to moisture or chemicals. With only two contact points, the slotted drive is the most basic drive style. The slot can't withstand much torque, so it's best to hand-tighten them instead of using power tools.
    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.
    Standard Profile—Standard-profile heads are the most common choice for flat head screws.
    Military Specification—These screws are manufactured and tested to meet strict U.S. military standards for material and construction.
