Brass-Tip Socket Head Screws
 |
 |
Protect surfaces from scratches and gouges. The brass tip on these screws is softer than other metal-tipped screws, so it won't damage hard plastic or soft metal, such as aluminum. If you need an even softer tip, choose nylon. The body of these screws is alloy steel, so they're still strong enough to hold components without wearing down. The deep, six-point socket on these screws 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.
