    Partially Threaded

    Our most vibration-resistant stainless steel screws. To lock them in place, secure a wire (sold separately) through a hole in their head. These screws won't loosen in moderate to heavy vibration. Their deep, six-point socket keeps hex keys from slipping out and damaging the drive.
    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 screws can.

    Our most vibration-resistant steel socket head screws. To lock them in place, secure a wire (sold separately) through a hole in their head. These screws won't loosen in moderate to heavy vibration. Made of alloy steel, they're some of our strongest screws. Their deep, six-point socket keeps hex keys 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.
