Non-standard Stepped High-Strength Steel Hex Head Screws with Phillips Drive

High-Strength Steel Hex Head Screws with Phillips Drive.

When clearance for a wrench is limited, these screws have a Phillips drive so you can install them with a screwdriver. With a tensile strength of 160, 000 psi, they are stronger than Grade 8 screws and can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. The cadmium plating provides good corrosion resistance to salt water. Screws meet NAS (National Aerospace Standards) specifications for material and construction. Length is measured from under the head.

Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine threads are closely spaced to prevent loosening from vibration.
