    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.

    These slotted cheese head screws won't rust or corrode from moisture and chemicals. They have a narrow profile, so they sneak past flanges and raised surfaces without snagging. With only two contact points, the slotted drive can't withstand much torque, so it's best to hand-tighten them.
    Length is measured from under the head.
