    Stainless Steel Cheese Head Slotted Screws

    Image of Product. Front orientation. Rounded Head Screws. Stainless Steel Cheese Head Slotted Screws.
    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.
    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.

    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.

    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.

    Corrosion-Resistant Stainless Steel
    18-8 Stainless Steel—The choice for wet and outdoor environments, these nuts resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
    Black-Oxide 18-8 Stainless Steel—Typically chosen for their appearance, these nuts have a dark, matte coating to create a finished look. They resist rust in wet and outdoor environments, but won'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 nuts 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 nuts will hold up in just about any environment, including salt water and most chemicals.

    Heat-Set Threaded Inserts for Plastic

    Standard

    Profile

    Create a secure base for fasteners in plastic, including brittle 3D printed parts. Press these inserts into straight holes that have been drilled, printed, or molded into plastic. Then, heat them with a soldering tip to melt the surrounding material. As the plastic cools, it fuses to the sharp, diagonal ridges around the inserts, which prevents them from being twisted or pulled out. The interior is fully threaded, so you can access the threads from both sides of a through hole. Also known as Chevron and headed inserts.
    Brass—Conductive and nonmagnetic, these inserts are useful for electrical applications. They resist moisture but aren't as strong as steel inserts.

    Fully

    Threaded

    The smallest standoffs we offer. These press into unthreaded holes to create permanent connections without welding, tapping, or installing extra hardware. The raised splines prevent rotation, and a recessed head clinches material for a strong hold. A through hole allows installation from one side, making them ideal for compact electronics like laptops and handheld devices.
    Wear-Resistant 400 Series Stainless Steel—These standoffs can grind against metal surfaces without denting or scratching. More corrosion resistant than steel.
