Steel Socket Head Screws with Flat Washer
 |  |
Fully Threaded | Partially Threaded |
Protect thin and soft surfaces from damage. A freely rotating washer sits between the head of these screws and your material to distribute pressure evenly. Made of alloy steel, these are 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.
