Stainless Steel Hex Head Screws
 |  |
Fully Threaded | Partially Threaded |
Won't rust or corrode when exposed to moisture and chemicals. These screws have a head with six flat sides to keep wrenches and sockets from slipping and rounding off the drive.
Length is measured from under the head.
Highly Corrosion-Resistant High-Strength Bumax 88 Stainless Steel—Comparable in strength to Grade 5 steel and as corrosion resistant as 316 stainless steel. These screws are commonly used in demanding applications, such as marine environments and chemical processing.
